Property and Application

Item	ZB-869	ZB-869A
Main Application	To be used in ABS,ASA,PC,PBT,ABS/PC alloys. To be used in PVC products, such as pipe, fitting, windows, low foam pipe, low foam board, To be used in PVC products which have special request on heat resistance.	To be used in ABS.ASA.PC.PBT.ABS/PC alloys. To be used in PVC products, such as pipe, fitting, windows ,low foam pipe, low foam board, To be used in PVC products which have special request on heat resistance.
Typical Characteristic	Enhance melt strength and elasticity, Improve the structure and strength of the foam hole. Enhance the control ability to the thermal form and process property. Reduce the contractibility of the products. Improve the strength of welding line. Improve the thermal stability of the semi-finished products for ABS,ABS/PC. Improve the brightness of the ABS film and sheets. Improve the heat resistant and improve the surface luster and transparency. Improve the resistance to solvent and scratch of PMMA.	The comprehensive property of ZB-869A is better than ZB-869 due to that ZB-869A is with higher molecular weight.
