Physical Properties


Impact Resistance

Saining PC board has the same outstanding impact resistance in the temperature range of -40℃ ~ +120℃ and in the outdoor long-term exposure as in the normal temperature. Its impact strength is 250-300 times that of ordinary glass, 30 times that of acrylic plate of the same thickness, and 2-20 times that of tempered glass. It will not crack when stricken by 1 kg hammer or fall from the height of 1 meter. It is reputed as "tempered glass".

Stable Performance under High Temperature

Saining multi-layer sheets have excellent strength and impact resistance under high temperature conditions, even after the expiration of the warranty period. At 80℃, Saining multi-layer sheets can still maintain 85% of their bending modulus as at room temperature.

Permissible continuous use temperature of the board (test standard UL746B)
UL Continuous Use Temperature

The temperature grade for continuous service set by UNDERWRITERS laboratory, is a trusted index used for measuring the performance of thermoplastic under long-term high-temperature environment. Various properties, especially important ones, of thermoplastics are tested at different temperatures. The results calculated that in 10 years, the performance changes of Saining sheet is no more than 50% of its original value.  

Fire Resistance Performance

Saining multi-layer panel has good fire-proof performance. Confirmed by the national standard GB50222-95, PC board is B1 level, Class 1 flame retardant. The ignition point of PC sheet is 580 ℃, and it extinguishes right after being deviated from fire. It produces no toxic gases when burning, and will not promote the spread of the fire.

Light Weight

It weighs only half of glass, saving the cost of transportation, loading and unloading, installation and supporting frame. Saining multi-layer panel is an ideal substitute for traditional lighting materials. It is safe, easy to operate, cut and install and tough. Compared with 6mm toughened glass, 10mm thick Saining multi-layer panel are 85% lighter in weight.

Sound Insulation Performance

PC board has excellent sound insulation effect, better than glass and acrylic board of the same thickness. The sound insulation of PC board is 5-9DB higher than that of glass. It is the first material of choice for highway noise barriers in the world.
