Transparent composites

Based on the high weather resistance, high Tg, and extremely low halogen content of the cycloaliphatic epoxy resin DE121, Donghua New Materials has developed a transparent composite solution. The solution has now gained recognition from downstream customers in multiple fields and is quietly driving upgrades in areas such as energy, electronics, lighting, and outdoor signage—from lightweight flexible photovoltaics to mobile phone back covers, from copper-clad laminates to outdoor signage—redefining "transparency" with excellent light transmittance, toughness, and environmental stability.

High-temperature resistant pultruded profiles

Based on the characteristics of cycloaliphatic epoxy resin—low viscosity, low halogen content, high Tg, high weather resistance, and excellent insulation performance—Donghua New Materials has developed a high-temperature resistant pultruded profile solution that is continuously supporting material upgrades in high-temperature operating fields such as power, petrochemicals, rail transit, industrial equipment, and municipal infrastructure. From power insulation structural components and high-voltage transmission and transformation supports to high-temperature resistant anti-corrosion profiles for the petrochemical industry, and from heat-resistant insulating parts for rail transit to high-temperature load-bearing components for industrial equipment, it provides excellent solutions for high-performance, high-temperature resistant pultruded composite application scenarios with outstanding high-temperature resistance, mechanical strength, weather resistance and durability, and electrical insulation reliability.

Weather-resistant pultruded profiles

Based on its core cycloaliphatic epoxy resin technology—low viscosity, high Tg, high weather resistance, and corrosion resistance—Donghua New Materials has developed a comprehensive weather-resistant pultruded profile solution. Whether in coastal environments with severe high-salinity mist corrosion, chemical plants with acid and alkali corrosion, or harsh outdoor environments exposed to year-round direct ultraviolet radiation, the weather-resistant pultruded profile solution based on Donghua cycloaliphatic epoxy resin remains as stable as ever—no chalking, no discoloration, no rusting, and no rotting. From photovoltaic frame structural components and photovoltaic mounting systems to high-voltage power transmission and transformation supports, Donghua New Materials continues to expand the application fields of high-performance weather-resistant pultruded composites with outstanding corrosion resistance, excellent mechanical properties, reliable flame-retardant ratings, long-lasting weather resistance, and stable electrical insulation performance.
