Why ASA Resin Is the Preferred Material for Outdoor Profiles & Sheets

Outdoor plastic profiles and sheets often fail not because of poor design, but because the material cannot withstand long-term UV exposure and weathering. Many manufacturers using ABS experience fading, surface cracking, or reduced impact strength after outdoor installation. ASA resin solves these issues by delivering superior weather resistance, color stability, and long-term outdoor performance.

ASA (Acrylonitrile Styrene Acrylate) resin is engineered specifically for exterior applications where durability under sunlight and harsh environments is essential. By replacing butadiene rubber with acrylic rubber, ASA offers significantly improved UV resistance compared to ABS, allowing products to maintain appearance and mechanical strength over extended outdoor use.

In outdoor profiles, ASA resin is widely applied in construction profiles, decorative panels, façade elements, and fencing systems. Its excellent color retention and smooth surface finish make it ideal for visible components that require long-lasting aesthetics with minimal maintenance.

For outdoor sheets and panels, ASA resin provides a reliable balance of toughness, rigidity, and weather stability. It is commonly used in roofing sheets, wall cladding, signage boards, and protective panels, where resistance to fading, cracking, and environmental aging is critical.

VIKEM offers a complete ASA material portfolio, including ASA resin, ASA impact modifier, ASA copolymer, and ASA granules, designed for extrusion and injection molding. Our ASA materials ensure stable processing, consistent quality, and dependable performance in outdoor applications, while also offering good compatibility with ABS and PVC systems.
