ACR-401 processing aid is a universal processing aid. It is an acrylic copolymer mainly used to improve the processing performance of PVC, promote the plasticization of PVC mixtures, in order to obtain good products at the lowest possible temperature and improve the quality of the products.This product is mainly used in the fields of PVC profiles, pipes, decorative panels, walls, etc. It can also be applied to PVC foaming agent products.

1. 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;
2. Improve the fluidity of PVC materials, making it easier to form and extrude, ensuring the stability of long-term processing and forming;
3. 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;
4. 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;
5. 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;
6. It can significantly reduce the deposition of various additives such as stabilizers, pigments, calcium powder, etc. on the surface of PVC products.
7. Good metal peelability, because ACR is a polymer material, it will not cause problems such as precipitation like lubricants.
A-401 is widely used in PVC hard products, such as PVC profile, PVC pipe, PVC pipe fittings and PVC foam board and so on.
25Kg/package or as required by customers.
The product should be kept clean during transportation and handling, prevent sunshine, rain, high temperature and humidity, and avoid damage to packaging. It should be stored in a cool, dry, sunless warehouse with temperature below 40 C for two year. It can still be used after two year' performance test.
