PVC Acrylic Processing Aid Additive ACR Impact Modifier CAS 25852-37-3

Product Description

Product Description:		ACR is a kind of polymer with special structure composed of methyl methacrylate (MMA), butyl acrylate by seed emulsion polymerizatio.
Product name:		PVC Impact Modifier ACR
Product model:		PVC Impact Modifier ACR 201/301/401/601
CAS Number:		25852-37-3
Purpose:		ACR 401 is used in PVC products, such as profiles, pipe, SPC or WPC flooring, etc.
Product shape:		White Powder

Processing aid ACR series products are the new generation of acrylate macromolecule copolymer. It was produced by using advanced polymerization and desiccation technical on the bases of our years producing experience. As it has low dust, non-corrosive, excellent fluidity and don't dissolve in water, it was considered to be an ideal processing modifier of PVC.
 

ACR is an acrylic processing aid as the main raw materials obtained through multiple polymerizations. It is a white, fine, non-toxic, and non corrosive powder.It is an auxiliary raw material added during the processing of PVC resin into PVC products to improve the processing performance of PVC.

Product Advantage

1. ACR processing aids can promote the melting of PVC, improve the surface finish, improve the elasticity of the melt, and enhance the elongation and strength of the melt.
2. It is beneficial to cover the bubbles and prevent the collapse of the cells. 
3. Ultra-high molecular weight and super-strong melt strength endow products with lower density and uniform cell structure, especially suitable for PVC foamed thick board products.
4. Give the product a uniform cell structure, high molecular weight and high melt strength, lower product density, and excellent processing  performance.
5. Good plasticizing ability, excellent melt fluidity, and good compatibility with PVC products, making the product more stable in size.
6.Excellent plasticizing performance, endowing the product with excellent processing performance and excellent surface gloss.

This processing aid has a wide range of applications. In addition to hard PVC products, it can improve the processing performance of semi-rigid PVC products and soft PVC products.

It is suitable for opaque PVC products that need good weather resistance, such as pipes, building materials (wall panels, door and window profiles, pipes, shutters, rain gutters, etc.), as well as injection molding and blow molding products
