Samyang Corporation TRIEL®
TRIEL®, a thermoplastic polyester elastomer(TPC-ET,TPEE,COPE) offers significant chemical resistance, thermal resistance, weatherability, and low temperature flexibility.
TPC-ET is a block copolymer composed of PBT hard segment and aliphatic ether ester soft segment. Having the same chemical structure as PBT, the hard segments is also known as PBT-Elastomer. PBT hard segment, a crystalline polymer, affects physical properties by forming crystalline in a polymer and produces mechanical strength like an engineering polymer. PTMG(Poly tetra methylene glycol) is used for aliphatic ether ester soft segment which gives flexible characteristics of rubber. TPC-ET is mainly composed of PBT. The higher the content of soft segment is, the lower TRIEL®’s hardness becomes. TRIEL®’s lowest possible hardness is approximately 28D(82A). TRIEL®’s rheological properties portray behaviors similar to that of engineering plastics. Changes in melt viscosity by processing method and sheer force resemble crystalline polymer.
Samyang Corporation retains TPV (Thermoplastic Vulcanizates) that covers the TPC-ET’s shortcomings such as high density and materialization of low hardness.
With its excellent properties, TRIEL® is mainly applied to automotive materials since automotive materials require long term mechanical performance and a wide range of thermal properties. TRIEL® is used in CVJB(Constant Velocity Joint Boots) which is crucial to a vehicle operation and requires flexural fatigue resistance. TRIEL® is supplied to various OEM companies and its outstanding properties are being recognized. TRIEL® has been adopted for use in rack & pinion steering boots and bellows based on its great thermal properties and toughness. Recently, Samyang Corporation entered air intake ducting area by developing a duct material which is used in airducts system. Damper boots protects the suspension from dirt, rocks, and other debris on the road. Having excellent thermal resistance, durability and compression set at high temperature, TRIEL® helps the damper boots to maintain their function from repeated suspension compression. TRIEL® is widely used in Korean OEM makers’ damper boots. Furthermore, TRIEL® offers a range of solutions for applications in airbag covers, a bush, boots, tube & hose and in numerous other situations demanding exceptional combination of chemical, thermal, electrical and mechanical characteristics.
With high adhesion to PC, PC/ABS, COPE materiel is widely used in double injection. By compounding SBS and SEBS, Samyang Corporation developed double adhesive material with PA6, PA6.6, and glass fiber reinforced PA.
When TPC-ET is applied to automotive & electronic cables, fiber, and films, halogen-free flame retardant chracteristics are often requested. TRIEL® can meet your needs. Halogen-freeflame retardant TPC-ET is generally limited in various applications due to degradation in tensile strength and tensile strain. But, samyang's TRIEL® minimized these shortcomings.
