-
It has good compatibility with PVC and good dispersion. ACR and PVC resin molecular chains are entangled together, which promotes the melting and plasticization of PVC, effectively reduces the melting temperature of PVC, and improves the product quality on the basis of small energy saving. weather resistance;
-
Improve the fluidity of PVC materials, making it easier to form and extrude, ensuring the stability of long-term processing and forming;
-
It can improve the melt strength of PVC materials, avoid melt fracture, solve surface problems such as shark skin, and improve the internal quality and surface gloss of products;
-
Effectively prevent pressure fluctuations and flow scars caused by extrusion molding during extrusion and injection molding, and avoid surface problems such as ripples and zebra crossings;
-
Improve the surface gloss of the product. Due to the uniform plasticization, it can also assist in improving the mechanical properties of the product such as tensile strength, impact strength, and elongation at break;
-
It can significantly reduce the deposition of various additives such as stabilizers, pigments, calcium powder, etc. on the surface of PVC products.
-
Good metal peelability, because ACR is a polymer material, it will not cause problems such as precipitation like lubricants.
PVC profiles, pipes, pipe fittings, decorative panels, wood-plastic, injection molding and other fields
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 40oC for two years. After two years, it can still be used after passing the performance inspection.
