What is the helmet glass made of?
Glass steel helmet with unsaturated polyester resin and special high strength alkali free glass fiber cloth as raw material, the process of modernization and strict inspection method developed, the product has high strength, good insulation properties, high temperature resistance, water resistance, acid, alkali, oil and chemical corrosion etc.. Applicable to mining, petroleum, chemical, smelting, high temperature and other industries.
Plexiglass (PMMA resin). PMMA is colorless and transparent, light transmittance is the best in plastic, higher than glass, light transmission range is large, reflectivity changes with the incidence angle, the absorption rate of light is small, can do total reflection. When the PMMA (carrier plate and rod bending) <480 conductive light; polymer atactic stereoblock type, but there is a separate short distance order, so the products are stretched and oriented crystalline structure, has good anti crazing, crazing resistance and impact toughness increase. Organic glass is divided into colorless, transparent, colored, transparent, pearlescent, embossed organic glass four.
Plastic PC (poly carbonate resin). PC - thermoplastic resin, excellent transparency, high impact resistance at room temperature, high temperature resistance, high rigidity, FDA grade, poor friction resistance, poor resistance. Usually used as a mirror material. Categories include anti-static PC, conductive PC, fiber reinforced fire retardant PC, UV resistant, weather resistant PC, food grade PC, chemical resistant PC.
