TPE材料的密度是多少:
1、 TPE材料的密度有大有小,也分為有填充物以及一些無填充物,tpe材料是由SEBS基材與其他混合物共混而成的彈性體顆粒,所以tpe的密度越大,填充物就越多。
2、 TPE材料有用進(jìn)口的原材料制作,也有國產(chǎn)的原材料制作,進(jìn)口和國產(chǎn)2者之間的密度都會(huì)有所不同,正常的密度在0.92~0.98之間。
3、 TPE材料的密度可以在0.84~2.0調(diào)整,通常注塑用的TPETPR軟性材料比重在0.9~1.25左右,一些特殊的TPETPR比重小或者超高。比重提升,可降低產(chǎn)品成本,但材料的拉伸強(qiáng)度及彈性,耐磨性均會(huì)有所下降,具體選擇哪種比重的材料要看產(chǎn)品要求。
