PVC processing aid attention

Weifang Yaxing Chemical Co.,Ltd | Updated: Jan 04, 2017

Different physical properties of PVC processing additive and PVC processing aid, using the methods are different, PVC processing aid products is divided into processing modifier and impact modifier. To improve impact properties for the purpose of using of the product known as impact modifier.
Processing PVC processing aid in PVC processing performance improvement as the main objective, it is usually caused by methyl acrylic acid methyl ester and methyl acrylate and acrylate graft copolymer.
PVC in processing in the need through heating and shear dispersed for uniform of melting State to forming, but PVC resin itself on heat and shear force of passed not strong, plastic of time more long, formed of melt body not uniform, effect products appearance and the mechanical performance, dang joined ACR processing additives Hou, can obviously improved PVC resin of melt body liquidity, and hot deformation sex and the products surface gloss, characteristics.
