Range of application
|
| Processing ingredient is popularly suitable for rigid, semi-rigid and soft PVC products. It received more visible additive effect on rigid PVC product, especially for injection molded items and secondary processed products, and it is very suitable for tubular goods, for example: extruded plate, profile shapes, blow extruded film, blow and injection molded item and foaming product etc. the general dosage is 1-3phr, and it is 3-6phr in injection molded item. . Application character ：
1. Increase the liquidity of material; decrease processing temperature; shorten processing time;
and realize the mixing uniformly.
 
2. Improve the stability and bath strength of PVC.
3. The product has proportional wall thickness and bright surface, it improve the dimensional accuracy and whiteness of the finished product.
4. Improve the heat stability and weatherability.
5. Remove the bad phenomena of tapping and degassing.
6. Increase the leg strength. |
