GWX Flame-Retardant Polycarbonate Sheet (Flame-Retardant PC Sheet)

GWX Flame-Retardant Polycarbonate Sheet is a high-safety engineering plastic sheet, manufactured from premium optical-grade or industrial-grade polycarbonate (PC) resin via advanced extrusion technology, integrated with high-efficiency flame-retardant additives (halogen-free or halogen-containing, optional) in the material matrix. It combines the inherent advantages of PC material—superior impact resistance, transparency, and weatherability—with excellent flame-retardant performance, effectively inhibiting combustion, delaying flame spread, and reducing smoke and toxic gas emission in case of fire.

Designed to meet strict fire safety standards, this product solves the flammability problem of standard PC sheets, providing reliable fire protection for buildings, electronic equipment, and public facilities. It is widely used in scenarios requiring high fire safety, clarity, and impact resistance, such as architectural partitions, electrical enclosures, and public area decorations.

Key Features

Excellent Flame-Retardant Performance

Adopts advanced flame-retardant technology, with flame-retardant grade up to UL94 V0 (the highest level for plastic sheets), and can also meet UL94 V2, V1, or other customized flame-retardant standards. It is self-extinguishing (self-extinguishing time ≤ 10 seconds), does not support combustion, effectively prevents flame spread, and reduces the risk of fire expansion. Halogen-free options are available, which emit less smoke and non-toxic gas during combustion, complying with environmental and safety requirements.

High Transparency & Optical Stability

While achieving excellent flame-retardant performance, it retains high light transmittance (up to 85%–92% for optical-grade), with clear vision, no obvious haze, no color distortion, and stable optical performance. The flame-retardant additives are evenly distributed in the material, not affecting light penetration, making it suitable for scenarios requiring both fire safety and high transparency, such as fire-resistant windows, observation panels, and light fixtures.

Outstanding Impact Resistance

Based on high-quality PC substrate, it boasts exceptional toughness and impact resistance—up to 25–30 times stronger than acrylic (PMMA) and shatter-resistant. Even in high-temperature fire environments, it can maintain a certain structural integrity, avoiding fragmentation and falling, reducing secondary damage caused by fire.

Wide Temperature Adaptability

Maintains stable physical, chemical, and flame-retardant properties in a wide temperature range of –40°C to 120°C, without warping, cracking, yellowing, or degradation of flame-retardant performance under extreme high or low temperatures. It is suitable for both indoor and outdoor harsh environments, and can work stably in high-temperature equipment surroundings.

Weatherable & UV-Resistant

Equipped with an optional UV protection layer, it can resist long-term outdoor UV radiation, avoiding yellowing, aging, or loss of performance. It has excellent weatherability, capable of withstanding rain, wind, sunlight, and other natural factors, ensuring stable flame-retardant effect and service life for years.

Non-Toxic & Environmentally Friendly

Halogen-free flame-retardant options are available, complying with international environmental standards (such as RoHS, REACH), non-toxic, odorless, and pollution-free. During combustion, it does not emit harmful halogen-containing gases, reducing environmental pollution and harm to human health, suitable for public places, medical facilities, and food-related fields.

Easy to Fabricate

Can be easily processed through cutting, drilling, cold bending, thermoforming, CNC machining, and bonding. The flame-retardant additives do not affect the processing performance of the sheet, which can be customized into various shapes, sizes, and thicknesses to meet the specific design needs of different fire safety projects.

Multifunctional Integration

Support integration of other functional treatments, such as anti-scratch, anti-static, anti-fog, and IR-blocking, on the basis of flame retardancy. It can be tailored to specific application needs, integrating multiple functions into one sheet to reduce product cost and simplify processing, while meeting both fire safety and functional requirements.
