Adding ACR (acrylic processing aid) to PVC products has multiple advantages, as shown below:
1、 Improved processing performance
Shorten plasticizing time:
ACR interacts with PVC molecular chains through polar groups, reducing inter particle friction, significantly shortening melt plasticization time, and improving production efficiency.
Improve melt flowability:
Optimize the flowability of PVC melt, reduce torque fluctuations during processing, and make the surface of the product smoother and more delicate.
Promote plasticization uniformity:
ACR can reduce surface wrinkles and bubbles and improve the overall uniformity of products for processes such as extrusion and rolling.
2、 Physical performance enhancement
Impact resistance and low-temperature toughness: The core/shell structure of ACR can effectively absorb impact energy, improve the impact resistance of products, and enhance toughness in low-temperature environments.
Weather resistance and stability: Improve the tolerance of PVC to environmental factors such as ultraviolet radiation and oxidation, and extend the service life of the product.
Surface smoothness improvement: making the surface of the product smoother and more delicate, enhancing its aesthetic appeal.
3、 Optimization of processing technology
Reduce energy consumption: Reduce equipment power consumption and lower production costs.
Compatibility enhancement: synergizes with different plasticizers to avoid plasticizer precipitation and maintain product flexibility.
4、 Expansion of application areas
Hard PVC products, such as door and window profiles, pipes, etc., require enhanced impact strength and weather resistance.
Soft PVC products: improve flexibility and tensile strength, while reducing the amount of plasticizers used.
Special processing scenarios: Low molecular weight ACR is suitable for filling thin-walled products, while high molecular weight products enhance melt strength.
summarize
ACR, as a plastic additive that combines processing modification and physical performance improvement, is widely used in various fields of PVC products, especially suitable for scenarios with high performance requirements.
