ASA

ASA Impact Modifiers

Shinepoly® offers a high-performance range of ASA impact modifiers(short for Acrylonitrile Styrene Acrylate) designed to enhance toughness, surface quality, and outdoor durability in styrenic thermoplastics. Built using a core-shell architecture—with an elastomeric core and a SAN shell—these additives deliver mechanical reinforcement without compromising appearance or processability.
Some of our ASA powder additives, such as LP2065X, combine excellent low-temperature impact resistance, UV stability, and chemical resistance with integral acrylic processing aid functionality, making them ideal for demanding environments where long-term visual and structural integrity is critical.

Engineered for Outdoor Performance and Dimensional Stability

styrenic resins such as AS, ABS, and PC/ASA blends are widely used across automotive, electronics, and appliance sectors—but often require modification to meet durability and processing demands. Shinepoly®’s acrylonitrile styrene acrylate impact modifiers provide targeted reinforcement while preserving gloss, colorability, and flow characteristics.

By leveraging a fine-tuned polymeric structure, these modifiers improve both mechanical and visual performance, supporting a broad range of manufacturing processes from high-speed extrusion to precision injection molding.

Core Functional Advantages

Superior Impact Strength

Enhances fracture resistance at ambient and low temperatures, allowing for tougher, more reliable parts across automotive, appliance, and electrical applications.

Long-Term Weatherability

Maintains performance in UV-exposed environments, ensuring sustained color retention and mechanical integrity for impact modified styrenic polymers.

Processing Efficiency

Acts as a multifunctional additive, with certain grades also offering benefits similar to an acrylic processing aid, improving melt flow and fusion.

Colorability and Surface Finish

Supports glossy surface appearance and stable pigmentation—ideal for coated or color-sensitive parts.

Thermal and Chemical Stability

Designed to resist heat deformation and aggressive cleaning agents, ensuring long-term durability in high-performance plastic components.

Applications

Automotive Exterior and Interior Components 

Automotive parts demand enduring aesthetics and toughness. Our ASA impact modifier range ensures components maintain critical gloss, high impact strength, and resist UV and weathering, preserving long-term visual and structural integrity while facilitating efficient processing of complex parts.

Electrical and Electronic Housings

For electrical and electronic housings, an ASA polymer base modified with our additives provides robust protection with essential chemical resistance and dimensional stability. This ensures impact protection, a premium finish, and enables precision in manufacturing through improved processability.

Appliance Components

Appliance components must withstand daily exposure to heat, UV, and cosmetic wear. Incorporating an ASA powder additive helps maintain structural integrity, vibrant color, and a lasting glossy finish, enhancing product longevity and supporting efficient molding.

Recreational Vehicles, Garden Tools, and Power Equipment 

Equipment for outdoor use, like recreational vehicles and garden tools, faces harsh conditions. Our Acrylonitrile styrene acrylate impact modifier delivers superior long-term weatherability, low-temperature toughness, and chemical resistance for durable, reliable performance under physical stress.

High-Gloss and Weatherable Polymer Blends

In high-gloss blends such as PC/ASA or PMMA/ASA, maintaining brilliant color, weatherability, and form retention is key. ASA, acting as a high-performance impact modifier for styrenics and engineering plastics, ensures exceptional surface aesthetics and lasting durability against environmental factors, often with improved melt flow for superior surface replication.

Specialized PVC and PC-Based Formulations

For specialized PVC formulations, particularly for outdoor use, ASA modifiers significantly enhance impact strength and long-term weather resistance. In PC-based blends, they improve toughness, UV stability, and stress crack resistance, broadening performance for demanding applications and often simplifying processing cycles.
