Celcon MC270-HM Ticona Acetal (POM) Copolymer is a high modulus, mineral coupled acetal copolymer. It utilizes a higher additive level to provide significant improvement in produc
 

POM是一種堅韌(ren)有(you)(you)(you)彈性(xing)(xing)(xing)的(de)材(cai)(cai)(cai)料(liao)，即使(shi)在低(di)溫下仍(reng)有(you)(you)(you)很好(hao)的(de)抗蠕變(bian)特性(xing)(xing)(xing)、幾何穩(wen)定性(xing)(xing)(xing)和抗沖擊特性(xing)(xing)(xing)。POM既有(you)(you)(you)均聚(ju)(ju)物(wu)(wu)材(cai)(cai)(cai)料(liao)也有(you)(you)(you)共(gong)(gong)聚(ju)(ju)物(wu)(wu)材(cai)(cai)(cai)料(liao)。均聚(ju)(ju)物(wu)(wu)材(cai)(cai)(cai)料(liao)具有(you)(you)(you)很好(hao)的(de)延展強(qiang)度(du)、抗疲勞強(qiang)度(du)，但不易于加工。共(gong)(gong)聚(ju)(ju)物(wu)(wu)材(cai)(cai)(cai)料(liao)有(you)(you)(you)很好(hao)的(de)熱穩(wen)定性(xing)(xing)(xing)、化(hua)學穩(wen)定性(xing)(xing)(xing)并且易于加工。無(wu)論均聚(ju)(ju)物(wu)(wu)材(cai)(cai)(cai)料(liao)還是共(gong)(gong)聚(ju)(ju)物(wu)(wu)材(cai)(cai)(cai)料(liao)，都是結晶性(xing)(xing)(xing)材(cai)(cai)(cai)料(liao)并且不易吸收水分。POM的(de)高(gao)結晶程度(du)導致它(ta)有(you)(you)(you)相當高(gao)的(de)收縮率，可高(gao)達到2%~3.5%。對于各(ge)種不同的(de)增強(qiang)型材(cai)(cai)(cai)料(liao)有(you)(you)(you)不同的(de)收縮率。
