Products Features
ACR and PVC have similar polarity, considerable affinity and good compatibility, and its functional characteristics are:
- At the processing temperature, it can promote the synchronous and uniform plasticization of PVC materials, improve thermal stability, effectively prevent local coking of materials, reduce processing molding temperature, shorten plasticization time, and improve production efficiency.
- Improve the fluidity of PVC materials, promote smooth processing, increase the yield of products, and reduce the mechanical wear of processing machinery.
- Significantly reduce the deposition of various additives on the surface of the machine, and significantly improve the appearance of finished products or semi-finished products such as smoothness.
Application field
This product is mainly used for PVC transparent products such as PVC film and PVC sheet. It can also be used in PVC foaming agent products.
Packaging and Storage
25Kg/bag. The product shall be kept clean during transportation, loading and unloading to prevent exposure to the sun, rain, high temperature and humidity, and to avoid damage to the package. It shall be stored in a cool, dry warehouse without direct sunlight and at a temperature lower than 40°C for two years. After two years, it can still be used after passing the performance inspection.
