Product Details

ACM Impact Modifier is an unique impact modifier which is an interpenetrating network copolymer (IPN ) with the structure of CPE grafted Polyacrylate . It has balance impact strength and toughness which endow it better performance than other general type impact modifiers like CPE and MBS.

Product advantage

· Excellent impact strength under low temperature

· Excellent toughness and hardness for PVC products.

· Better weather-resistance

· better surface glossiness for PVC finished products
