TPE材料與哪些材料相似?
1、PVC的優(yōu)點(diǎn):軟膠PVC彈性良好;耐老化、耐酸堿性優(yōu)良;并且PVC成本較為低廉;可快速注塑加工成型。
PVC的不足:含有毒鹵素元素氯,氣味大;可能含有毒塑化劑及重金屬;燃燒可能釋放致癌物質(zhì)二噁英;低溫易變脆,彈性差;存在變形。
2、硅膠的優(yōu)點(diǎn):耐高溫(200~250℃);手感爽滑;高彈性,變形小;無氣味,環(huán)保無毒;耐老化,耐弱酸堿;較容易通過食品級LFGB橄欖油測試及FDA177.2600正己烷測試。
硅膠的不足:成型周期較長;材料不能回收再次使用;包覆成型性較差.
3、橡膠的優(yōu)點(diǎn):高耐磨;回彈性,抗撕裂性好;變形小;機(jī)械性能好;耐高溫;耐腐蝕。橡膠的不足:加工工序多,生產(chǎn)周期長;物料不能回收再使用;材料氣味大,環(huán)保性堪憂;
4、TPE和TPU都屬于軟性材料,都具有良好的橡膠彈性.相比較而言,TPE在觸感的舒適度方面更為,TPU則更多的呈現(xiàn)優(yōu)異的彈性和強(qiáng)度.較低硬度的產(chǎn)品(如30A以下),需選用TPE,可以起到防滑緩沖減震回彈的效果.而對于較高硬度(80A以上)的要求彈性好的產(chǎn)品,用TPU才能勝任。
