HIGH PERFORMANCE GRADE TEEE MATERIAL
TEEE materials 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.
TEEE material 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 TEEE and makes it act like rubber
while the hard segment endows processing properties to make it just
like plastics. In contrast to engineering plastics, TEEE exhibits
same good strength but better flexibility and dynamic mechanical
properties.
High performance grade SUNPRENE® TEEE material 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.
