GWX Light Diffuser Polycarbonate Sheet (PC Light Diffusion Sheet)
GWX Light Diffuser Polycarbonate Sheet is a high-performance optical plastic sheet, manufactured from premium optical-grade polycarbonate (PC) resin through advanced extrusion technology, integrated with uniformly distributed light diffusion additives or processed with a professional frosted surface finish. It efficiently refracts, reflects, and scatters incident light in multiple directions, converting point or linear light sources into uniform, soft surface illumination, while retaining the inherent advantages of PC material—superior impact resistance, weatherability, and durability.
Designed to solve the problems of glare and uneven lighting caused by direct light sources, this product minimizes visible hot spots, improves visual comfort, and maintains high light transmittance. It is widely used in various lighting systems and scenarios where uniform, soft, and glare-free illumination is required, such as commercial lighting, architectural lighting, and display backlighting.

Key Features
1
Excellent Light Diffusion Performance
Adopts advanced light diffusion technology, with a haze value of 90%–98% (adjustable according to requirements), ensuring uniform light scattering. It can effectively convert concentrated light from LED, fluorescent, or other light sources into soft, even illumination, eliminating hot spots and glare, and creating a comfortable visual environment without harsh light stimulation.
2
High Light Transmittance & Optical Stability
While achieving high diffusion effect, it retains excellent light transmittance (up to 75%–90%, adjustable based on diffusion level), maximizing light utilization and avoiding unnecessary light loss. The optical performance is stable, with no obvious color distortion or light decay, ensuring consistent illumination effect for long-term use.
3
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. It can withstand accidental impact, collision, and external pressure, ensuring safety and long service life in public areas, commercial spaces, or industrial environments.
4
Wide Temperature Adaptability
Maintains stable physical, chemical, and optical properties in a wide temperature range of –40°C to 120°C, without warping, cracking, yellowing, or degradation of diffusion performance under extreme high or low temperatures. It is suitable for both indoor and outdoor lighting applications.
5
Weatherable & UV-Resistant
Equipped with a UV protection layer, it can resist long-term outdoor UV radiation, avoiding yellowing, aging, or loss of optical performance. It has excellent weatherability, capable of withstanding rain, wind, sunlight, and other natural factors, ensuring stable light diffusion effect for years.
6
Flame-Retardant & Safe
Available with flame-retardant grade (UL94 V2–V0), meeting international safety standards for construction, electronic, and public facilities. It is non-toxic, odorless, and compliant with environmental protection requirements, ensuring safe use in various lighting scenarios, including public buildings and residential areas.
7
Easy to Fabricate
Can be easily processed through cutting, drilling, cold bending, thermoforming, CNC machining, and bonding. It can be customized into various shapes, sizes, and thicknesses, and the diffusion level and light transmittance can be adjusted according to specific lighting requirements, meeting the design needs of different projects.
8
Long-Lasting Performance
The light diffusion effect is integrated into the material (additive type) or surface (frosted type), ensuring permanent performance that will not fade or fail due to friction, cleaning, or long-term use. It has a long service life, reducing maintenance and replacement costs for users.
