style="text-indent:25px">pp塑膠原料具有良好的耐熱性，制品能在100℃以上溫度進(jìn)行消毒滅菌，在不受外力的條件下，150℃也不變形。脆化溫度為-35℃，在低于-35℃會(huì)發(fā)生脆化，耐寒性不如聚乙烯。對(duì)于pp塑膠原料玻璃化溫度的報(bào)道值有一18qC, OqC, 5℃等，這也是由于人們采用不同試樣，其中所含晶相與無(wú)定形相的比例不同，使分子鏈中無(wú)定形部分鏈長(zhǎng)不同所致。pp塑膠原料的熔融溫度比聚乙烯約提高40一50%，約為164一170℃, 100%等規(guī)度pp塑膠原料。但在室溫和低溫下，由于本身的分子結(jié)構(gòu)規(guī)整度高，所以沖擊強(qiáng)度較差。pp塑膠原料突出的性能就是抗彎曲疲勞性，俗稱百折膠。</p><p
