Additives for ABS,ASA,PC PVC
Processing aid ZB-869
Brief Introduction
ZB-869 series is styrene-acrylonitrile copolymer with ultra-high molecular weight which reaches to 5million.It is processing aid for ABS,ASA,ABS/PC alloy. It is also the foam adjustment agent for PVC products. I t can also be used in the PVC products which have special request on heat resistance.
It is white powder. It is not dissolved in water, alcohol, but can be easily dissolved in Ketone, chloroform.
The sanitary index is in accordance with GB-9681-88

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 rudiments 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 anti-solvent and scrap resistance of PMMA. | The comprehensive property of ZB-869A is better than ZB-869 DUE TO THAT zb-869a IS WITH HIGHER MOLECULAR WEIGHT. |
