The application and functions of ACR (acrylic ester polymer) in PVC (polyvinyl chloride) mainly include the following aspects:
Improving impact resistance: ACR can effectively enhance the impact resistance of PVC, making it perform better in low-temperature environments and enhancing its durability.
Improving processing performance: The addition of ACR can reduce the viscosity of PVC melt, increase its fluidity, reduce melt cracking, enhance the surface smoothness of products, thereby improving processing efficiency and product quality.
Enhanced thermal stability: ACR helps to improve the thermal stability of PVC, prolong the processing time of materials at high temperatures, prevent degradation, and ensure that PVC materials maintain stable performance during production.
Promote plasticization: ACR can significantly shorten plasticization time, accelerate melting, promote plasticization, improve surface glossiness of products, and make the appearance smoother and more delicate.
Core shell structure characteristics: ACR has a core-shell structure, which enables it to exhibit excellent impact resistance, low-temperature toughness, weather resistance, and processability in PVC products. This structure enables ACR to have better performance and price ratio in PVC products.
Application areas of ACR in PVC products:
Hard PVC products: ACR is widely used in hard PVC products such as pipes, profiles, sheets, foam materials, etc., especially suitable for outdoor use.
Transparent products: ACR exhibits good transparency and surface smoothness in transparent products, suitable for fields such as pharmaceutical packaging and consumer goods packaging.
Chemical composition of ACR:
ACR is a thermoplastic graft polymer, which is mainly polymerized by methyl methacrylate and butyl acrylate through seed lotion.
