5℃等，這也是由于人們采用不同試樣，其中所含晶相與無定形相的比例不同，使分子鏈中無定形部分鏈長不同所致。聚丙烯的熔融溫度比聚乙烯約提高40一50%，約為164一170℃, 100%等規(guī)度聚丙烯熔點(diǎn)為176℃。聚丙烯的化學(xué)穩(wěn)定性很好，除能被濃硫酸、濃硝酸侵蝕外，對其它各種化學(xué)試劑都比較穩(wěn)定，但低分子量的脂肪烴、芳香烴和氯化烴等能使聚丙烯軟化和溶脹，同時(shí)它的化學(xué)穩(wěn)定性隨結(jié)晶度的增加還有所提高，所以聚丙烯適合制作各種化工管道和配件，揭陽文具膠帶膠芯定做價(jià)格，防腐蝕效果良好，揭陽文具膠帶膠芯定做價(jià)格。制作膠帶膠芯的原材料pp塑料：為減少內(nèi)應(yīng)力及變形，應(yīng)選擇高速注射，但有些等級(jí)的PP和模具不適用。揭陽文具膠帶膠芯定做價(jià)格</p><div
