AIM Impact Modifier

Description

AIM (acrylic impact modifier) is an advanced modifier designed with a distinctive core–shell structure. The core is moderately crosslinked to provide toughness, while the shell is composed of a graft copolymer that enhances compatibility with PVC matrices. This structural design enables AIM to significantly improve the impact strength, weather resistance, and surface gloss of finished products. Owing to these properties, AIM has become a preferred solution for applications requiring both durability and long-term outdoor performance.

Key Performance Features

• Excellent weather resistance – ensures long service life for outdoor applications without significant performance degradation.
• Superior impact strength – greatly enhances toughness and durability of PVC products.
• Low extrusion shrinkage – contributes to better dimensional stability during processing.
• Enhanced surface appearance – provides smooth, glossy finishes for improved aesthetics.
• Wide processing window – offers versatility in different PVC processing conditions, improving production efficiency.
