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.

If you would like to know the price differences between different brands of ACR-401, or want a detailed comparison with other types of processing aids, I can provide you with more information.

Advanced Performance in PVC Processing

ACR 401 Processing Aid significantly improves the quality and efficiency of PVC manufacturing. Its acrylic polymer composition boosts surface smoothness, melt strength, and promotes rapid fusion, making it a key additive for extrusion, calendaring, and injection molding applications. Its excellent thermal stability at typical PVC processing temperatures ensures consistent results even under demanding industrial conditions.

Safety and Storage Guidelines

This non-toxic, odorless processing aid is specifically formulated for ease of handling and environmental safety. With a purity of at least 98% and a pH of 7, it poses minimal risk during use. For best performance and to maintain its shelf life of 12 months, store ACR 401 in a cool, dry place, away from direct sunlight and any moisture infiltration. Always keep packaging securely closed.

FAQ's of ACR 401 PROCESSING AID:

Q: How is ACR 401 Processing Aid applied in PVC manufacturing?

A: ACR 401 is added directly to PVC formulations during compounding. The typical usage rate ranges from 0.5 to 2.0 parts per hundred resin (phr), but optimal dosage should be determined based on the specific process and application, such as extrusion or injection molding.

Q: What benefits does ACR 401 provide in PVC processing?

A: This processing aid enhances melt strength, promotes rapid fusion, and improves overall surface quality. Its use results in increased productivity, smoother product appearance, and stable processing even at elevated temperatures.

Q: What are the storage recommendations for ACR 401 Processing Aid?

A: Store ACR 401 in a cool, dry environment away from direct sunlight and moisture. Keeping the packaging closed when not in use helps to maintain its stability and effectiveness for up to 12 months.

Q: When should I consider using ACR 401 Processing Aid in my PVC production process?

A: ACR 401 should be used whenever you require improved processability, better fusion, and enhanced surface quality in PVC products, particularly in extrusion, calendaring, or injection molding applications.

Q: Where is ACR 401 most commonly utilized?

A: This additive is commonly used in PVC processing industries including piping, profile, sheet extrusion, calendaring, and related fields. It is suitable for operations that demand high thermal stability and smooth finished products.

Q: What is the physical form and appearance of ACR 401?

A: ACR 401 is supplied as a white, free-flowing powder, with a bulk density of 0.45-0.55 g/cm3 and a particle size below 150 microns, making it easy to disperse and handle during production.
