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.

About us

Company details

Samyang Group launched a holding company system in November 2011 to separate the manufacturing division and the investment division. These divisions enhance the transparency of corporate governance and corporate value. The holdings company, Samyang Holdings, has Samyang Corporation and other companies as subsidiaries. Samyang Holdings focuses its capabilities on specialist business areas by establishing a governance structure that enables a speedy and professional decision making, based on each business group's characteristics and by boosting its competitiveness

Since 1924, when Chairman Kim Yeon-su established Samyang Corporation to reward Korea by fostering industries, the Samyang Group has continuously solidified its operation through the philosophies of middle-of-the-road principled management and trust management. Samyang completed Ulsan's first modern factory, a sugar manufacturing plant, in 1955, and a polyester fiber plant in Jeonju in 1969, thereby contributing greatly to Korean nationals supply of clothes and food. Thereafter, Samyang expanded into the chemical, food, medical, industrial material, PET bottle and trade businesses. Embracing its vision of becoming a company of "Ingredients that Add Value to Life", Samyang is growing in the chemical, food, medicine, and new business fields.

Under the scheme, Samyang will continue its growth in the three key fields of chemicals, food, and medicine through the strategy of selection and concentration. Also, Samyang will secure market leadership through innovation and will foster new businesses as its new growth engines.
