Endurance Sole PU Resin is a polymer having a urethane segment repeating structural unit made by reacting an isocyanate with a polyol. Compared with ordinary rubber soles, polyurethane soles have the characteristics of light weight and good wear resistance. The polyurethane sole is made of polyurethane resin as the main raw material, which solves the problems that the domestic plastic bottom and the recycled rubber bottom are easy to break the bottom and the rubber bottom is easy to open. By adding various additives, the polyurethane sole has been greatly improved in terms of wear resistance, oil resistance, electrical insulation, antistatic and acid and alkali resistance. The author researched the use of new processing technology, molding process and design, the safety performance of the shoes is more stable, and the wearing is beautiful and comfortable, durable.

China Endurance Sole PU Resins were originally used only for everyday wear, and extended to work shoes and protective safety shoes as impact resistance, perforation resistance and slip resistance improved. Currently, 15% of the world’s safety shoes are made of polyurethane soles. In the future, sports shoes and casual shoes were successfully developed. Nowadays, sports shoes are already high-tech products. Because of the variety of sports, the requirements for sports shoes are different. In order to enable athletes to fully develop their abilities, sports shoes can not be ignored. Polyurethane soles have a promising future in gymnastics, track and field, and ball. At present, polyurethane soles are constantly improving, focusing on wet aging, low temperature performance and light stability. In short, the microporous polyurethane sole is a promising product.

1. Sole PU Resin Liquid usually form various bubbles in the production, with elasticity, light weight, wear resistance, folding resistance, oil resistance, chemical resistance, corrosion resistance, etc., PU shoe material with microporous polyurethane elastomer Soft, comfortable to wear, warm, flexible, shockproof and non-slip.

2. Polyurethane sole is divided into encryption type and foaming type. The encrypted polyurethane bottom is very light, moderate in hardness and hardness, hand-made, wear-resistant and wear-resistant, easy to maintain, and it is not easy to open the bottom. The foamed polyurethane has a small amount of ingredients and is naturally soft, but it is not wear-resistant and is not easy to open. Once it is opened, it cannot be repaired.

3. China Sole PU Resin Liquid are widely used in the production of casual shoes, sports shoes, work shoes, sandals, travel shoes, men’s and women’s leather shoes, protective shoes, etc. Adhesives are used to bond the polyurethane sole and the shoe upper, because of the lightness. Therefore, the degumming rate is lower than the rubber bottom. .

4. Polyurethane sole is divided into high school and low end. The high-density polyurethane sole has strict requirements from formula to process to production. After the shoes are shipped, they have a shelf life of up to 5 years. The shoes with such soles are mostly high-end shoes, and the price is relatively high. The shoes produced by these soles are all rubber-padded shoes. The polyurethane sole used in the middle and low grade shoes has a shelf life of about half a year. These soles are not adhesive tapes. They are seams, but the durability of the soles is not as good as the former. The durability is not as good as the former. It will rupture like tofu.

The White Sole PU Resin is very light, the glue rate is better than the rubber bottom and the beef bottom, and the comfort is better than the rubber bottom and the beef bottom.

Polyurethane base, good dimensional stability, long storage life; excellent wear resistance, flexural resistance; excellent shock absorption, anti-slip performance; better temperature resistance; good chemical resistance. However, the bottom of the polyurethane is divided into two types: the encrypted polyurethane base and the foamed polyurethane base.

The foamed polyurethane density is lower than that of the encrypted polyurethane base. The foamed polyurethane base is softer than the encrypted polyurethane. The foamed polyurethane base weight is also lower than that of the encrypted polyurethane base. To be lighter, the cost of the foamed polyurethane base is also half the cost of the encrypted polyurethane base. The gloss of the foamed polyurethane base is not as bright as that of the encrypted polyurethane; the foamed polyurethane bottom is not as durable as the encrypted polyurethane.

The wear resistance of the Pale Yellow Sole PU Resin is 5 times that of the ordinary rubber sole, and the wear resistance of the foamed polyurethane bottom is one-half of that of the ordinary rubber sole.

Foamed polyurethane soles are used in the manufacture of medium and low-grade leather shoes, sports shoes, high-end leather shoes, sports shoes, travel shoes, etc.

PU Resin For Women Casual Shoes, collectively known as polyurethane, is a general term for macromolecular compounds containing repeating carbamate groups in the backbone. It is formed by the addition of an organic diisocyanate or a polyisocyanate with a dihydroxy or polyhydroxy compound. The polyurethane macromolecule may contain, in addition to the carbamate, a group such as an ether, an ester, a urea, a biuret or an allophanate. Depending on the raw materials used, there are products of different nature, generally polyester and polyether. Can be used in the manufacture of plastics, rubber, fiber, rigid and flexible foams, adhesives and coatings. Polyurethane is an emerging organic polymer material. It is known as the “fifth largest plastic” and is widely used in construction, automotive, light industry, textile, petrochemical, metallurgy, electronics, national defense, medical, for its excellent performance. Machinery and many other fields.

In 1937, Professor Otto Bayer of Germany first discovered that polyurethanes were obtained by PU Resin For Casual Shoes of polyisocyanates with polyol compounds. Based on this, they entered industrial applications. In the United States and the United States, the manufacturing technology of polyurethane resins was obtained from Germany in 1945 to 1947. Industrialization has begun. In 1955, Japan introduced polyurethane industrial production technology from Bayer Corporation of Germany and DuPont Company of the United States. At the end of the 1950s, China’s polyurethane industry began to take off, and it has developed rapidly in the past 10 years.

Since the groups contained in the macromolecule of the Low-Hardness Shoe Sole PU Resin are all highly polar groups, and the macromolecule also contains a polyether or a polyester soft segment, the polyurethane has the following characteristics:

1 high mechanical strength and oxidation stability;

2 PU Resin For Casual Shoes has high flexibility and resilience;

3 has excellent oil resistance, solvent resistance, water resistance and fire resistance.

Polyurethane has a wide range of uses due to its many excellent properties.

Polyurethane is mainly used as polyurethane synthetic leather, polyurethane foam, polyurethane coating, polyurethane adhesive, urethane rubber (elastomer) and polyurethane fiber. In addition, polyurethane is also used in civil engineering, address drilling, mining and petroleum engineering to block water, stabilize buildings or subgrades; as paving materials, for runways in sports fields, indoor floors of buildings, etc.

The Low-Hardness Shoe Sole PU Resin is very light, the glue rate is better than the rubber bottom and the beef bottom, and the comfort is better than the rubber bottom and the beef bottom.

Polyurethane base, good dimensional stability, long storage life; excellent wear resistance, flexural resistance; excellent shock absorption, anti-slip performance; better temperature resistance; good chemical resistance. However, the bottom of the polyurethane is divided into two types: the encrypted polyurethane base and the foamed polyurethane base.

The Medium-Density Shoe Sole PU Resin density is lower than that of the encrypted polyurethane base. The foamed polyurethane base is softer than the encrypted polyurethane. The foamed polyurethane base weight is also lower than that of the encrypted polyurethane base. To be lighter, the cost of the foamed polyurethane base is also half the cost of the encrypted polyurethane base. The gloss of the foamed polyurethane base is not as bright as that of the encrypted polyurethane; the foamed polyurethane bottom is not as durable as the encrypted polyurethane.

Switzerland, Taiwan, Thailand, the Netherlands, Turkey, the United Arab Emirates and the United Kingdom. A total of 11,455 professionals from 49 countries and regions were attracted to visit and negotiate business. The number of visitors has increased by 14.91% compared to 2015. The international audience reached 375 people.

Starting from 2016, the leather shoe material exhibition was held at the same time as the finished shoe exhibition was held in the same place. The name of the exhibition was updated to the International Shoes Exhibition in New Delhi, India. The exhibition covered more extensive content and attracted more professional exhibitors to visit.

According to reports: the old-fashioned developed countries and regional consumer markets have become saturated and stable after years of development market demand, and the subsequent development potential is not enough. Asian and Central American countries such as India, China, Indonesia, Brazil and other countries have a large population and good economic development, and become the most potential consumer market in the future footwear market.

Polyurethane Prepolymer For Shoe Sole has many advantages: low density, soft texture, comfortable and light to wear; good dimensional stability, long storage life; excellent wear resistance, flexural resistance; excellent shock absorption, anti-slip performance; better temperature resistance Good chemical resistance and so on. Polyurethane is mostly used in the manufacture of high-grade leather shoes, sports shoes, travel shoes and so on.

It is divided into wet and dry methods. It is a polymer solution system with transparent or slightly turbid appearance. The solid content is about (30-35)%, which means that (65-70)% is solvent. Simply say that 1 ton of slurry contains (650-700) kilograms of solvent. For dry processes, it contains so much toluene and methyl ethyl ketone. The amount of toluene is larger because of the better solubility of toluene. In other words, it contains 650-700 kg of pure DMF. Therefore, for the slurry, the price changes of toluene and DMF greatly affect the cost of the slurry, which is very simple.

Polyurethane And Isocyanate For Shoe Sole slurry is used as a coating to prepare polyurethane synthetic leather and artificial leather. Polyurethane synthetic leather has soft and natural luster, soft handfeel and strong leathery appearance. It has excellent mechanical properties such as excellent adhesion to substrates, abrasion resistance, flexing resistance, anti-aging, and anti-fungal properties. It has the advantages of good cold resistance, breathability, washing, convenient processing and excellent price. It is the most ideal substitute for natural leather. It is widely used in clothing, shoes, luggage, furniture, sports and other industries. It is an alternative to the field of dermis application, and it can also be applied to areas where the dermis is not applicable. The dermis market is very susceptible to animals (bovine, sheep, pigs, etc., mad cow disease).

Dry Polyurethane Slurry – In the process of application, the solvent in the slurry is evaporated by heating and evaporation. The solvent is mostly made of toluene and methyl ethyl ketone. The solvent evaporated cannot be recycled, which not only pollutes the environment, but also causes no The necessary waste.

Wet polyurethane slurry – because the process is to extract DMF with water (because DMF and water have unlimited solubility), it is more environmentally friendly, and the synthetic leather produced has good moisture permeability and breathability. Soft, full, light, and more natural leather style and appearance, so the development speed is amazing.
