Description
[technical field]
The present invention relates to a kind of TPE, the TPE Alloy And Preparation Method of particularly a kind of xylon and SEBS.
[background technology]
Thermoplastic elastomer TPE (Thermoplastic Elastomer) is a kind of snappiness with rubber, high strength, high resilience, but have the feature of injection moulding processing again, have environment-protecting asepsis safety, durometer level is wide, good tint permanence is arranged, soft-touch, weathering resistance, fatigue resistance and temperature tolerance, processing characteristics is superior, need not vulcanize, can recycle and reduce cost, both can the quadric injection mould moulding, with body material coating and bondings such as PP, PE, PC, PS, ABS, also moulding separately.
Thermoplastic elastomer had both had the processing characteristics of thermoplastics, had the physicals of vulcanized rubber again, was the advantage combination of plastics and rubber advantage.Thermoplastic elastomer is capturing the manor that only belongs to vulcanized rubber originally without restraint.Over year, the fast development of electronic apparatus, communication and automobile industry has driven the high speed development in thermoplastic elastomer city surplus in the of nearly ten.
TPE can be divided into two big classes: segmented copolymer (styrene resin, copolyester, urethane and polymeric amide), and thermoplastic elastomer blend and alloy (TPO and Thermoplastic Vulcanizate), wherein SEBS (styrene-ethylene-butylene-styrene segmented copolymer) and SBS (styrene-butadiene-styrene block copolymer) just belong to segmented copolymer.But the xylon alloy that does not also occur a kind of SEBS at present.
