该产品为白色粉末，具有优异的热稳定性，能满足行星挤出机对各种半透或不透明硬质片材的挤出压延要求。广泛运用于各种挤出压延硬片的生产加工，如封边条、广告膜、吸塑膜、灯罩、PVC卡片等，在不改变客户加工配方的基础上，每100公斤PVC粉根据客户生产制品及要求的不同添加3.0-5.5公斤该稳定剂，可完全替代有机锡稳定剂，并且能消除因使用有机锡而产生的气味，同时能提高制品的维卡、热收缩等指标。

该产品为钙锌稳定剂，具有比有机锡稳定剂更好的环保等级，能满足欧盟和美国对最新版的ROHS和REACH环保指标的要求。

The product is white powder characterized in excellent thermal stability, and can meet the extrusion and calendering requirements of the planetary extruder for various semi-transparent or non-transparent rigid sheets. It is widely used in the production and processing of various extruded and calendered rigid sheets, such as edge banding strips, advertising films, blister films, lampshades, PVC cards. Without changing the processing formula of customers, 3.0-5.5kg of the stabilizer can be added to every 100kg of PVC powder according to different products and requirements of the customers to replace the organotin stabilizer completely, thus eliminating the odor generated by the use of organotin, while improving the indexes such as Vicat softening temperature and thermal contraction of the products.

The product is a calcium-zinc stabilizer, whose environmental protection grade is better than organotin stabilizers, and can meet EU and US requirements on the environmental protection indexes in the latest ROHS and REACH.
