2、 Application characteristics of thermoplastic rubber sebs-yh533
Yh-533 has the highest molecular weight among linear SEBS, excellent mechanical properties under high filling and complete double InP network formed when blending with pp. it is mainly used for blending products. Yh-533 has good mechanical properties and oil filling performance. Yh-533 is mainly used as the basic material of blended elastomer, such as various coating materials, sealing strips, anti vibration materials, road sign paint, reinforcement of other elastomers, toughening and modification of plastics, etc. Yh-533 can be blended with most plastics during processing, and different plastics have different effects on the properties of its final products. For example, when powdered PPO is added to yh-533 blend, the phase separation of styrene and butadiene is strengthened, and the temperature resistance, mechanical properties, rigidity and surface smoothness of the elastomer are significantly enhanced; Add an appropriate amount of α- The copolymer of methylstyrene and propylene * * * does not stick to the surface of the product. |
