Hytrel杜邦TPEE HTR8667--The following is a brief introduction toTPEE thermoplastic elastomer, and more details about HytrelHTR8667and TPEE materials originally manufactured by DuPont.Welcome to inquire!
杜邦TPEE HTR8667--Elastomer TPEE plastic material can be regardedas the third generation of synthetic material. This is because TPEEmaterial is a block copolymer material composed of semi crystallineor glass thermoplastic resin and relatively soft elastomer.Therefore, in terms of performance, it not only has the highelasticity of rubber, At the same time, it also has the proprietarythermoplastic processing performance of thermoplastic resin. Thestructural feature of TPEE is that two different vertical segmentsand comparative segments are composed of chemical bonds. The resinsegment can form a physical cross-linking phenomenon by virtue ofthe force between the chain segments, while the rubber segment is ahigh elastic chain segment with great free rotation ability, Theresin and rubber segments are automatically arranged and connectedin an appropriate order. The structural characteristics andcrosslinking state of polymer chains like this have reversibility.Usually, thermoplastic elastomers will show a series of physicaland mechanical properties such as the strength, elasticity anddeformation characteristics of vulcanized rubber at roomtemperature. If they are at higher temperature, The physicalcrosslinking of the resin segment will also show reversible changeswith the change of temperature, which obviously shows theprocessing characteristics of TPEE thermoplastic materials.
杜邦TPEE HTR8667--TPEE plastic material has very good tensilestrength and elasticity. At the same time, its wear resistance andfatigue resistance are also very good. It is worth mentioning thatit is also very easy to dye and color. It can be directly carriedout whether injection molding or extrusion molding. There are noother special processes. It is very good and cheap, Special plasticelastomer materials with such properties are mostly used to makevarious rubber products, synthesize modifiers of various resinmaterials, and can be used as adhesives. In addition, some asphaltmodifiers, such as TPEE, will show immeasurable plasticity with thechange of temperature environment, They have high hardness and goodwear resistance. The most important thing is that they have goodelasticity. This is the outstanding performance advantages ofelastomer materials such as TPEE. After tests, it is found thatelastomer plastic materials have very excellent underwater soundabsorption materials, and their sound absorption performance willbe affected by curing temperature, chain extender content and otherparameters to a certain extent, However, if the filler is added tochange its structure, it can further improve the underwateracoustic performance of elastomer materials.
