Polyurethane Elastomer (PU Elastomer for short) is a polymer material with excellent elasticity, wear resistance, corrosion resistance, anti-aging, anti-skid, sound insulation and flame retardancy. Polyurethane elastomers are divided into two types, one is two-component and the other is one-component.
MDI series is a kind of polyurethane elastomer, and its main raw material is MDI (4,4'-diphenylmethane diisocyanate). The characteristics of MDI series polyurethane elastomers are mainly determined by raw materials and formula ratios.
Advantages and characteristics of polyurethane elastomer MDI series:
1. Excellent wear resistance and high elasticity: MDI series polyurethane elastomers have extremely high elasticity, can well adapt to various human body shapes and the surface of objects, and can provide durable wear resistance for long-term use.
2. Waterproof and chemical corrosion resistance: MDI series polyurethane elastomers have a wide range of applications and can be used in underwater and corrosive environments.
3. Excellent temperature resistance: MDI series polyurethane elastomers can be used in a wide temperature range and can well withstand the influence of extreme temperatures.
4. Good flame retardant performance: MDI series polyurethane elastomer is a kind of flame retardant material, which can be used to make fireproof products.
5. Simple manufacturing process: MDI series polyurethane elastomers have good processing performance and can be processed into products of various shapes by injection molding, casting, coating and other methods.
