1. Definition of thermoplastic elastomer
Thermoplastic elastomer is a kind of environment-friendly and low-carbon composite material with rubber properties (high elasticity, compression and permanent deformation, etc.) and plastic processing properties (simple process).With rubber is a kind of high elasticity, high resilience, but also has the characteristics of injection molding processing, environmental non-toxic safety, wide range of hardness, and excellent color, texture soft, weathering resistance, fatigue resistance and low temperature resistance and processing performance is superior, no cure, can be recycled to reduce costs, either the secondary injection molding, and the PP/PE/PS/PC/ABS matrix materials such as coated adhesive, also can separate molding.
2. TPE, for all of the thermoplastic elastomer referred, namely contains the TPR/TPU/TPV/TPEE/TPO/TPAE.
3.TPR is the name of users in Taiwan and even in Asia. The first person to use SBS synthetic modification to make a rubber, this rubber for thermoplastic, is thermo-plastic Rubbe, TPR.
4. TPV for PP and EPDM blend of dynamic vulcanized elastomer, TPV can, in fact, as a class of TPO, just because of its special dynamic vulcanization system, gives its good comprehensive performance: TPV solvent resistance, high temperature resistance and mechanical strength will be better than that of SEBS system TPE, TPR, TPV is currently the most successful and widely used rubber blending elastomer, as a result, the TPV listed separately.
5.TPU, thermoplastic polyurethane.It is made of MDI containing NCO functional group and POLYOL and 1.4bg containing OH functional group by extruding and mixing.Therefore, it is widely used in extrusion, flow, calendering, dissolving into solution resin and other processing methods. It is a plastic material often used by the plastic processing industry. Its products cover the range of industrial applications and civil necessities.TPU has a transparent appearance and a hardness of 65A~80D.
