What is AIM Acrylic Impact Modifier ？

📝Product Description

AIM (Acrylic Impact Modifier) is an additive specifically designed for polyvinyl chloride (PVC), aimed at significantly enhancing the impact strength, weather resistance, and processability of PVC products.

AIM features a core-shell structure, where the core consists of a moderately crosslinked acrylic copolymer, while the shell is formed through graft copolymerization with methacrylate. This structure not only enhances PVC's toughness and impact resistance but also improves surface gloss, making it particularly suitable for products requiring long-term outdoor use.

AIM offers excellent processing properties, is suitable for high-speed extrusion, and possesses good thermal and light stability. It is widely used in various rigid PVC products.

🚀Applications

AIM impact modifiers are extensively used in rigid PVC products, particularly suited for outdoor and transparent applications, including: 

1️⃣PVC Profiles:

 Such as door/window frames, guardrails, and fencing, enhancing impact resistance and weatherability.

2️⃣PVC Pipes & Fittings:

 Improving pipe toughness and resistance to external impacts, suitable for drainage pipes, water supply pipes, etc.

3️⃣PVC Sheets: 

Used in building materials and signage, providing excellent surface gloss and durability.

4️⃣Transparent Products:

 Such as corrugated sheets, films, and architectural transparent panels .

5️⃣Others:

 Including cable jackets, outdoor decorative materials, and other products requiring high weather resistance and impact strength.

⏩Performance Advantages:

Significantly enhances impact strength and low-temperature flexibility in PVC products.

Improves weather resistance, suitable for outdoor products exposed to prolonged UV radiation and harsh weather.

Facilitates PVC melting, boosting processing efficiency and suitability for high-speed extrusion.

Enhances surface gloss and dimensional stability while reducing post-extrusion shrinkage.

Maintains superior transparency and clarity in transparent products.
