Polyurethane or isocyanate polymer. Polyurethane is an elastomer between plastic and rubber. Its excellent and unique comprehensive properties are not available in ordinary plastics and rubber. It is a polymer material. Polyurethane is an emerging organic polymer material, known as the "fifth largest plastic", and is widely used in many fields of the national economy because of its excellent performance. Product application fields include light industry, chemical industry, electronics, textile, medical care, construction, building materials, automobiles, national defense, aerospace, aviation, etc. Let’s take a look at pu polyurethane products and features as well as the application scope of pu polyurethane.
Introduction to polyurethane
Polyurethane material is the abbreviation of polyurethane, and its English name is polyurethane, which is a polymer material. Polyurethane is an emerging organic polymer material, known as the "fifth largest plastic", and is widely used in many fields of the national economy because of its excellent performance. Product application fields include light industry, chemical industry, electronics, textile, medical care, construction, building materials, automobiles, national defense, aerospace, aviation, etc.
PU polyurethane products and features
Features: Polyurethane elastomer has wear resistance, chemical corrosion resistance, tensile strength, high elasticity, high pressure load resistance, and wear resistance strength High, shock-absorbing, tear-resistant, radiation-resistant, high strength, high load-bearing and shock-absorbing buffering and other good properties. At the same time, it has a wide hardness range, from Shore A10-100. Currently, there are products exceeding Shaw A100 and above. It has superior shock-absorbing and shock-absorbing cushioning pads. It is more impact-resistant than metal springs and does not damage the mold.
Main products:
1. Polyurethane plates, rods and tubes.
2. Industrial accessories: casings, flexible couplings, oil seals, etc., industrial glue sticks, papermaking equipment, printing, chemical industry, wood processing equipment, various mechanical materials, various hardware mold springs wait.
