热塑性弹性体(TPE)一种有弹性的聚合物,该材料的机械性能主要与材料本身的硬度(范围可从邵氏A到邵氏D)和在不同的环境或工作条件下的特性有关。TPE材料可以分为很多种。

一、聚醚嵌段酰胺(PEBA)

它是一种的先进的聚酰胺弹性体,具有良好的性能,如弹性,柔韧性,低温恢复性,耐磨性和耐化学性等。适用于高科技产品方面的应用。

二、苯乙烯类热塑性橡胶(SBS,SEBS)

它是一种苯乙烯类热塑性聚合物。SBS和SEBS弹性体最常用于生产各种需要弹性,柔软触感和美观的产品。它们适合用于为特定产品而设计的定制配方中。与SBS相比,SEBS在某些特定应用中表现更好,因为它更好地抵抗紫外线的氧化作用,其工作温度甚至可达120°C;SEBS可以通过包覆成型技术和热塑性塑料(PP,SAN,PS,ABS,PC-ABS,PMMA,PA)混合,以满足美观或功能性方面的设计需求。

它是属于聚酯(聚酯TPU)和聚醚(聚醚TPU)族的聚合物。它是一种具有很高的抗撕裂性,耐磨性和耐割性的弹性体。)。产品硬度可以从邵氏70A到70D。此外,TPU还有出色的回弹性,即使在极端的温度下也能保持良好的特性。

四、热塑性硫化橡胶(TPV)

该聚合物的组成包括弹性体硫化橡胶(或交联的硫化橡胶)。这种硫化/交联过程使得TPV具有优异的热塑性,弹性和柔韧性等特点。

Thermoplastic elastomer (TPE) an elastic polymer whose mechanical properties are mainly related to the hardness of the material itself (which can range from shaw A to shaw D) and its properties in different environments or operating conditions。 TPE materials can be divided into many types。

I。 polyether block amide (PEBA)

It is an advanced polyamide elastomer with good properties such as elasticity, flexibility, low temperature recovery, wear resistance and chemical resistance. Applicable to the application of high-tech products.

Styrene thermoplastic rubber (SBS, SEBS)

It is a styrene thermoplastic polymer. SBS and SEBS elastomers are most commonly used to produce a variety of products that require flexibility, soft touch and aesthetic appearance. They are suitable for use in customized formulations designed for specific products. Compared with SBS, SEBS performs better in certain applications because it is better able to resist uv oxidation and its operating temperature can even reach 120°C. SEBS can be mixed with thermoplastics (PP, SAN, PS, ABS, pc-abs, PMMA, PA) through envelop molding technology to meet aesthetic or functional design requirements.

Thermoplastic polyurethane (TPU)

It is a polymer belonging to the polyester (polyester TPU) and polyether (polyether TPU) families. It is an elastomer with high tear resistance, abrasion resistance and cut resistance. The product hardness can be from shaw 70A to 70D. In addition, the TPU has excellent resilience and maintains excellent properties even at extreme temperatures.

4。 Thermoplastic vulcanized rubber (TPV)

The polymer comprises elastomer vulcanized rubber (or crosslinked vulcanized rubber). This vulcanization/crosslinking process gives TPV excellent thermoplastic, elastic and flexible properties.
