black flame retardant pc sheet
Features
Flame retardant performance
Compliant with international flame retardant standards (such as UL94 V-0, EN 13501-1 B1 level), with a limit oxygen index (LOI) of ≥ 28% and a self extinguishing time of ≤ 10 seconds after ignition.
There are no droplets during combustion, reducing the risk of secondary fires, and the smoke density is low (in accordance with ASTM E662 standard).
Mechanical performance
High impact strength (cantilever beam notch impact strength ≥ 8kJ/m ²), more than 200 times that of ordinary glass.
Bending strength ≥ 90MPa, bending modulus ≥ 2200MPa, combining lightweight and structural stability.
Optical performance
Transmittance ≥ 88% (thickness ≤ 6mm), haze ≤ 1.5%, close to the transparency of glass.
High color uniformity, customizable matte, frosted and other surface effects.
Weather resistance and environmental adaptability
Excellent resistance to ultraviolet (UV) aging, passed ISO 4892 artificial accelerated aging test, with an outdoor service life of ≥ 10 years.
Wide temperature resistance range (-40 ℃~120 ℃), short-term high temperature resistance up to 150 ℃, and no brittle fracture at low temperatures.
Processing and installation friendly
Support precision machining processes such as laser cutting, CNC engraving, and hot bending forming.
The surface hardness reaches HB~2H (which can be increased to 3H by hard coating), and the scratch resistance is strong.

Advantages
Safety and Compliance
Proactively meet the flame retardant requirements of building codes (such as GB 8624 China Fire Protection Standard), rail transit (EN 45545-2), and the electronic and electrical industry to reduce compliance risks.
Lightweight and economical
The density is only 1.2g/cm ³, which is 50% lighter than tempered glass and reduces transportation and installation costs by more than 40%; At the same time, reduce the amount of supporting structures used.
Comprehensive performance balance
Achieving the best balance between flame retardancy, transparency, and strength, superior to traditional flame retardant ABS or PVC sheets.
Environmental sustainability
Recyclable and reusable (compliant with GRS certification), with low VOC emissions during the production process, meeting LEED green building standards.
