What are the advantages of polyurethane elastomers

Polyurethane elastomer has excellent comprehensive properties, and its modulus is between that of general rubber and plastic. It has the following properties:
1. High strength and elasticity, polyurethane elastomer can maintain high elasticity in a wide range of hardness (as low as Shore A10, as high as Shore D90);
2. Under the same hardness, the bearing capacity is higher than other elastomers;
3. Excellent wear resistance, its wear resistance is 2~10 times that of natural rubber;
4. Excellent grease and chemical resistance;
5. Polyurethane elastomer has excellent UV resistance, oxidation resistance, ozone resistance, radiation resistance, weather resistance and other properties;
6. Excellent fatigue resistance and vibration resistance, suitable for high frequency deflection applications;
7. High impact resistance; good low temperature flexibility; generally no plasticizer can achieve the required hardness, so there is no problem caused by plasticizer migration;
8. Using specially formulated polyurethane, it can withstand high temperature of 150⁰C;
9. The molding process is diverse and simple, and the processing and mold costs are low.

Polyurethane elastomer
Compared with metal materials, the characteristics of polyurethane elastomers are:
1. Lightweight;
2. Low noise;
3. Wear resistance;
4. Low processing cost;
5. Strong corrosion resistance;
Compared with plastics, polyurethane elastomers are characterized by:
1. Not brittle;
2. Elastic memory;
3. Good abrasion resistance;
Compared with rubber, polyurethane elastomers are characterized by:
1. Better wear resistance;
2. More resistant to cutting and tearing;
3. Higher carrying capacity;
4. Can be transparent or translucent;
5. Better chemical and weather resistance;
6. Wider hardness range;
7. Various processing methods, lower mold and processing costs;
8. Greener, healthier and more energy efficient;
