HIGH PERFORMANCE GRADE THERMOPLASTIC POLYETHER-ESTER ELASTOMER
Thermoplastic polyether-ester elastomer are block copolymers
consisting of a hard segment of polyester and a soft segment based
on polyether or polyester.among which, polyether soft segment and
non crystalline polyester comprise amorphous phase while polyester
hard segment partly crystallizes to form crystal domain as physical
crosslink point.
Thermoplastic polyether-ester elastomer combines the desirable
elasticity of rubber and the strength of engineering plastics.
Compared with rubber, it shows better processing properties and
longer service life. The soft segment endows elasticity for
thermoplastic polyether-ester elastomer and makes it act like
rubber while the hard segment endows processing properties to make
it just like plastics. In contrast to engineering plastics,
thermoplastic polyether-ester elastomer exhibits same good strength
but better flexibility and dynamic mechanical properties.
High performance grade SUNPRENE® thermoplastic polyether-ester
elastomer exhibit high structural strength, favorable melt
strength, good resistance to creep, impact, flex fatigue and
abrasion, outstanding toughness, resilience and good dimensional
stability. They have flexibility at low temperatures; and good
retention of properties at elevated temperatures. The use
temperature ranges from －50℃～＋180℃. In addition, the grades could
resist the corrosion caused by some industrial chemicals, oils and
solvents.
