PVC processing aid

详情

ACR (acrylic resin copolymer) is a commonly used PVC processing aid with multiple functions and advantages. ‌
Definition and basic characteristics:
ACR stands for Acrylics, a type of polymer copolymer that is typically a flowable white powder, non-toxic, non corrosive, and classified as a non hazardous material. Its particle size is relatively fine, with a true density between 1.***1.*0g/cm ³.
The main use of ACR is as a processing aid, which can significantly shorten plasticization time, accelerate melting, promote plasticization, make plasticization uniform, reduce bubbles, and improve the surface glossiness of products.
The main functions of ACR in PVC products include:
Promoting plasticization: In hard PVC products, ACR can significantly shorten plasticization time, improve melt rheological properties, and enhance the dispersibility of other additives.
Improving surface quality: ACR can reduce wrinkles on the surface of the product, enhance melt extensibility, overcome melt rupture, and achieve uniform thickness of the product.
Improving glossiness: ACR can significantly enhance the surface glossiness of products, making them appear smooth and delicate.
