气泡调节剂 Air bubble modifier
产品介绍：product description:
PVC气泡调节剂是由丙烯酸酯等单体通过乳液聚合工艺制得，主要用于改善硬质PVC 发泡制品的泡孔均匀度，促进PVC树脂塑化、熔融，提高制品的外观质量。用于加工助剂时， 能大幅度提高熔体强度，赋予制品更佳的表面光洁度。用于发泡调节剂时赋予制品更高的 熔体强度，较佳的塑化性能和流动性，促进PVC的凝胶化，使发泡剂受热分解产生的气体 尽快且完全溶解在PVC熔体中，与PVC分子链相互缠绕，大大提高了熔体的强度和弹性， 使PVC熔体能够产生和膨胀气体相适应的强度和气体膨胀化必须的伸长率，以保证气体在 增大过程中形成细小致密的又相互独立的泡孔，能够保留更多均匀致密的气泡，从而获得均 匀的发泡结构，更低的密度和更佳的表面光洁度。产品为白色无定形粉末，不溶于水、乙醇， 在醴、酮、氯代燃中能溶解或溶胀。产品符合卫生标准（GB9681 -88）。
P-530/P-533 series is foaming regulator made from acrylate monomer by emulsion polymerization process. I t is mainly used to improve the uniformity of the foaming hole, Promote fusion and melt, improve the surface quality of the finished product.
When it is used as processing aid, it can enhance the melt strength, endow better surface brightness.
When it is used as foaming regulator, it can endow higher melt strength, better fusion and fluidity, promote gelation of PVC. It make the gas, generated from decomposition while vesicant is heated, dissolved in PVC melt body as quickly as fully, then it intertwists with the PVC molecular chain, the strength and elasticity of the melt body is improved greatly.
It can have the foamed product keep down well-distributed and compact air bubble, Thus form homogeneous foaming structure.
It is white powder, it can be dissolved in ketone and chloroform, but not in water and alcohol.
技术指标：Ouality Specification

应用特点:
优异的综合性能，适用于所有制品，特别适合于厚壁制品。流动性好，适合于高填充配方。
在PVC挤出低发泡制品中添加发泡调节剂，能促进PVC的凝胶化，提高熔体的热强度及延伸性；改善制品的表面质量；使发泡剂形成的细微泡孔稳定，不使泡孔壁破裂而相互穿透而形成大孔，故所得的泡沫不仅密度小而且强度好。
 
Application features:
Excellent comprehensive performance, suitable for all products, especially suitable for thick-walled products. Good fluidity, suitable for high filling formulations. Adding foaming regulator in PVC extruded low-foaming products can promote the gelatinization of PVC, increase the thermal strength and extensibility of the melt; improve the surface quality of the products; make the fine bubble holes formed by the foaming agent stable, so that the bubble wall does not break and penetrate each other to form large holes, so the obtained foam not only has low density but also good strength.
