Electrical Grade Fiberglass Polyester
Glastic UTS GPO-2 is a premium-grade fiberglass reinforced thermoset polyester laminate developed for demanding electrical and industrial applications that require a combination of excellent insulation performance, flame resistance, and mechanical durability. Manufactured using high-quality glass fiber reinforcements and polyester resin systems, this material provides reliable performance in environments where electrical safety, structural integrity, and dimensional stability are critical.
Known for its outstanding dielectric properties, Glastic UTS GPO-2 is widely used in electrical equipment, switchgear assemblies, control panels, transformers, and power distribution systems. Its ability to maintain electrical insulation under varying environmental conditions makes it a preferred material for components exposed to voltage stress, heat, and mechanical loads. The material also offers excellent arc and tracking resistance, helping improve the safety and reliability of electrical systems.
One of the key advantages of Glastic UTS GPO-2 is its flame-retardant performance. Designed to meet stringent safety requirements, it helps reduce flame propagation and supports the production of safer electrical and industrial equipment. In addition to its fire-resistant characteristics, the material exhibits high mechanical strength and rigidity, allowing it to withstand impact, vibration, and continuous operational stresses without compromising performance.
Glastic UTS GPO-2 also delivers excellent dimensional stability and low moisture absorption, ensuring consistent performance even in humid or challenging environments. Its superior machinability allows manufacturers to easily fabricate custom parts, including terminal boards, bus bar supports, electrical barriers, mounting panels, spacers, and structural insulation components. The material can be cut, drilled, punched, and machined with precision, making it suitable for both standard and complex engineering applications.
Due to its combination of electrical insulation, flame resistance, mechanical strength, and fabrication versatility, Glastic UTS GPO-2 is widely utilized across electrical, power generation, transportation, industrial automation, and heavy equipment industries. It remains a trusted solution for engineers and manufacturers seeking a dependable laminate material for critical electrical and structural applications.
