Acrylic impact modifier KRT-22

Acrylic impact modifier is an acrylate copolymer with core-shell structure, the core is an acrylate copolymer with mild crosslinking and shell is methyl acrylate copolymer. It can improve PVC products’ shock resistance, at the same time it can also improve the heat stability and light stability of products.

Description:

1. Acrylic impact modifier is new type impact modifier

2. Modified acrylic polymer can increase the product surface gloss, improve the product anti-aging properties,

3. Especially suitable for outdoor products.

Product Description:

ACR series Impact Modifier is a Weatherable Acrylic Impact Modifier used in rigid PVC products. It is a "core -shell" structure modifier, with cross-linked poly butyl acrylic as "core"and graft methyl methacrylate as "shell". It not only improves impact resistance performance of the product, but also increases the surface gloss of the product, and especially the weatherability of the product. It is especially suitable for outdoor products and broadly used in PVC profiles, sheets, boards, pipes, pipe fittings, etc.

Product characteristics:
Compared to CPE and other impact modifiers, ACR series products have the following advantages:
(1). Imparts excellent low-temperature impact resistance. Excellent weatherability.

(2). Improves product surface gloss greatly. Wide processing range for high speed extrusion.
(3). Improves impact strength and imparts good rigidity of product.
