About ACR 401 PROCESSING AID

ACR-401 is one of the most commonly used acrylate processing aids in the PVC plastics industry. It effectively solves problems in PVC material processing, such as accelerating plasticization and improving the surface finish of products.

| Chemical Nature | Copolymer of methyl methacrylate (MMA) and acrylates |

| Physical Form | White, free-flowing fine powder |

| Core Functions | Promotes melt plasticization, increases melt strength, and improves product surface quality |

| Main Uses | Rigid PVC products, such as pipes, profiles (doors and windows), sheets, and fittings |

| Typical Dosage | 1-10 parts per 100 parts of PVC resin, depending on the product |

| Common Packaging | 20-25 kg/bag (kraft paper bag or woven bag) |

Its effects are mainly reflected in two aspects: processing performance and final product quality:

* Optimizes the processing process: ACR-401 can entangle with PVC molecular chains, significantly shortening plasticization time and making melting more uniform. It also improves melt strength, preventing problems such as melt fracture and surface roughness during extrusion.

* Improved Product Quality: By promoting uniform plasticization, it reduces surface defects such as fisheyes, crystal points, and ripples, improving surface gloss and smoothness. It also helps improve certain physical and mechanical properties of the product.

In summary, ACR-401 is a fundamental additive that significantly improves the processing performance of PVC. If you encounter problems such as slow plasticization, poor melt strength, or unsatisfactory surface finish in rigid PVC production, adding ACR-401 is usually a direct and effective solution.
