1.Details
ACR-401 processing aid is an acrylic copolymer mainly used to improve the processing performance of PVC, promote the plasticization of PVC mixtures, and obtain products with good plasticization at the lowest possible temperature, thereby improving product quality. This product is mainly used in the field of PVC products such as PVC profiles, pipes, plates, fences, etc. It can also be used in PVC foaming agent products. This product has excellent processing performance; Good dispersibility and thermal stability; And it can make the product have a good surface gloss. Good compatibility with PVC and good dispersibility. The entanglement of ACR and PVC resin molecular chains promotes the melting and plasticization of PVC, effectively reducing the melting temperature of PVC and improving product quality while saving a small amount of energy. Weather resistance; Improve the fluidity of PVC materials to make them easier to shape and extrude.
2.Product advantages
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.
