Clear transparent sheet made from thermoplastic copolyester . it offers extreme clarity and light transmission in combination with high gloss . polyester petg sheet has very good impact resistance , even at low temperatures , and is approved for food contact applications 公司自創(chuàng)建以來就本著“以市場為向?qū)?,以科技為動力,以?chuàng)新求發(fā)展,以質(zhì)量求生存的經(jīng)營理理念,樹立了良好的商業(yè)信譽。
The flame retardancy and the comprehensive performance of polyesters were improved . the reactive flame retardant used is 2 - carboxyethl ( phoyl ) phosphinic acid ( cepp ) , and the layered silicate selected is organic montmorillnite ( o - mmt ) . when the contents of cepp and o - mmt are 3wt % , respectively , loi value of the copolyester / montmorillnite composite reaches 32 % 當阻燃劑和蒙脫土的含量均達到3時,復合材料的限氧指數(shù)可達32以上,阻燃劑和蒙脫土表現(xiàn)出良好的協(xié)同阻燃作用,同時復合材料在熱穩(wěn)定性能以及結(jié)晶性能等方面也有所改善。
Copolyester forms when modifications are made to polyesters, which are combinations of diacids and diols. For example, by introducing other diacids, such as isophthalic acid (IPA), or other diols, such as cyclohexane dimethanol (CHDM) to the polyester polyethylene terephthalate (PET), the material becomes a copolyester due to its comonomer content.
