ACR Impact Modifiers

Shinepoly® ACR impact modifiers(short for Acrylic Core-Shell Impact Modifier) are designed to improve impact strength, weather resistance, and melt processing across a variety of engineering thermoplastics. Featuring a core-shell acrylic structure, they enhance durability at both room and sub-zero temperatures while also supporting better flow characteristics during extrusion and molding.
With a unique ability to function as both an impact modifier and a processing aid such as our LP2082 , our ACR Impact modifiers provide compounders with a streamlined solution to balance mechanical performance, aesthetic requirements, and manufacturing efficiency.

Optimized for Blended Systems and Harsh Environments

Applications using polycarbonate, PC/ABS, and PC/PBT blends often require enhanced resilience under impact and exposure to outdoor elements. Shinepoly®’s ACR impact modifiers address these needs by improving low-temperature ductility, colorability, and UV stability.

At the same time, they contribute to smoother melt flow, easier dispersion, and reduced die buildup—functional characteristics typically expected from an acrylic processing aid. These benefits make them suitable for both structural and appearance-critical parts in automotive, electronics, and consumer product sectors.

Key Performance Highlights

Superior Low-Temperature Toughness

Maintains flexibility and energy absorption under extreme cold, ideal for outdoor-use components made from impact modified acrylic or polycarbonate blends.

Enhanced Weatherability

Delivers long-term resistance to UV degradation, discoloration, and thermal aging, ensuring material longevity in exposed applications.

Improved Processing Stability

Provides melt control and dispersion benefits common to ACR processing aids, helping reduce cycle time and maintain surface uniformity.

Excellent Surface Finish and Color Consistency

Supports even pigmentation and post-paint adhesion, especially useful for molded or coated parts.

Broad Compatibility

Tailored for engineering-grade materials like PC, PBT, PC/ABS, and select PVC formulations, where both impact strength and processing behavior must be optimized.

Applications

Shinepoly® ACR impact modifiers are well suited for high-performance plastic products requiring a careful balance of toughness, aesthetics, and efficient processability. Typical use cases include:

Automotive parts exposed to low temperatures and physical stress

Electrical/electronic housings needing rigidity and surface smoothness

Appliance casings requiring impact durability and visual appeal

Garden and lawn equipment, often subject to UV and mechanical wear

Recreational vehicles and outdoor fixtures designed for rough use

Extruded or molded PVC components where the material benefits from an acrylic processing aid for PVC that also contributes to structural strength

These modifiers are ideal where multifunctional performance is expected from a single additive system.

Engineered for Polymer System Versatility

Unlike conventional additives that only address one property, Shinepoly® ACR impact modifiers are engineered to serve multiple functions in complex polymer systems. Their ability to improve both mechanical performance and melt behavior helps processors reduce the number of ingredients needed in a formulation, simplifying supply chains and boosting consistency.

Supplied in a free-flowing white powder form, they integrate seamlessly into compounding processes and maintain excellent batch-to-batch stability.
