Rohm Launches PMMA Material For Highly Exposed Outdoor Environments

Rohm announces the launch of ACRYLITE® SunResistThis is a breakthrough achievement in its surface protection technology and the first material of its kind in Röhm Americas' ACRYLITE® brand PMMA (polymethyl methacrylate, acrylic) product line.

This product is specifically designed for those pursuingDurability, Aesthetics, and Production EfficiencyProduced by the manufacturer, setting a new benchmark for outdoor applications, suitable for applications including: door and window structures, terrace panels, outdoor furniture, building facades, and applications requiring outdoor use.Strong exposure to outdoor environmentMaintaining excellent performance and appearance in leisure and entertainment components.

Ultra-thin co-extruded protective layer, blocking harmful ultraviolet rays

Outdoor products are constantly subjected to the tests of ultraviolet light, sudden temperature changes, and wear.

ACRYLITE® SunResist is a PMMA molding compound specially formulated to formUltra-thin co-extruded protective layereffectively blocksHarmful ultraviolet radiation below 400 nm, helping to maintain color and surface integrity and reduce fading and aging after prolonged use.

In addition to excellent UV resistance and weatherability, ACRYLITE® SunResist offers outstanding weather resistance, maintaining its color and gloss even under prolonged exposure to sunlight and humid conditions, making it ideal for applications requiring…Elegant appearance all year roundthe components.

Premium surface texture, balancing aesthetics and strength

ACRYLITE® SunResist imparts to finished productsHigh-end surface quality：

· Precise Gloss Control

· High surface hardness and wear resistance

Excellent chemical resistance

Achieve a high-end appearance without sacrificing structural strength.

Its high impact resistance and thermal stability enhance mechanical properties, allowing it to be used at high temperatures.Prevent stress cracking, warpage, and deformation。

Processing-friendly, enhancing production efficiency

For fabricators, ACRYLITE® SunResist offersHigh liquidity Wide processing window, enabling smoother extrusion/co-extrusion, helping to reduce scrap rates and improve overall production efficiency.

The product exhibits adaptation to the substrateIndustry-leading adhesionThis helps prevent edge chipping during cutting and avoids delamination of the protective surface layer, which is especially critical for complex profiles, cut-to-length parts, and subsequent processing steps.

Core Performance

UV Resistance & Weather ResistanceHigh absorption of UV light below 400 nm, effectively resisting photodegradation and color shift.

Colorfastness to Light (Xenon Arc Weathering, ASTM G155 Cycle 1)Accelerated aging tests show that the product significantly reduces visible color difference after long-term use, ensuring long-lasting appearance for outdoor products.

Mechanical and Thermal PropertiesHigh flexural strength, notched Charpy impact strength of cantilever beam, and high heat deflection temperature, resistant to bending, impact, and high-temperature deformation.
