Product Features
- 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 and 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.

Packaging and Storage
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 40°C for two years. After two years, it can still be used after passing the performance inspection.
Frequently Asked Questions (FAQ)
What is the primary application of ACR-401?
ACR-401 is widely used in PVC processing fields including PVC profiles, pipes, pipe fittings, decorative panels, wood-plastic (WPC), and injection molding to improve processing stability and product quality.
How does ACR-401 improve PVC processing efficiency?
It features excellent compatibility and dispersion with PVC. By entangling with PVC resin molecular chains, it promotes melting and plasticization while reducing the melting temperature, which saves energy and improves weather resistance.
Can ACR-401 resolve surface defects in PVC extrusion?
Yes. ACR-401 improves the melt strength of PVC, preventing melt fracture and eliminating surface issues like shark skin, ripples, and zebra crossings caused by pressure fluctuations during extrusion.
Does ACR-401 cause additive precipitation on the metal mold?
No. ACR-401 is a polymer material with excellent metal peelability. Unlike traditional lubricants, it does not cause precipitation issues and significantly reduces the deposition of stabilizers, pigments, and calcium powder on the product surface.
What are the packaging and storage requirements for ACR-401?
It is packaged in 25Kg bags. It must be stored in a cool, dry warehouse below 40°C, away from direct sunlight, rain, and high humidity. Avoid package damage during transport and handling.
What is the shelf life of ACR-401?
The standard shelf life is two years under proper storage conditions. After two years, it can still be used if it passes the performance inspection.
