CARBON
Ingredients: a special carbon fiber consists mainly of carbon fiber, its carbon content types varies,generally above 90%.
Features: high temperature resistance, wear clean, electrical conductivity, thermal conductivity and
corrosion resistance, small proportion of carbon fiber, it has a high specific strength.
Use: high costs, mainly used in high-end helmet on.Rendering with tessellation or gluing and EPS forms, mainly strengthened hard hat frame structure, increase external impact penetration resistance.
FRP
Ingredients: glass fiber reinforced plastic, generally refers to glass fibre reinforced unsaturated polyester, epoxy and phenolic resin matrix.
Features:light and hard, to electricity, high mechanical strength, recycled less corrosion resistance.
Use: high cost, in the more frequent locomotive used on the helmet, main and EPS bonded form, resistance strengthened hard hat frame structure.
ABS
Ingredients: ABS acrylonitrile (23%-41%), butadiene (10%-30%) and styrene (29%-60%) three copolymerization monomer into polymer.
Features: has toughened ABS, rigid, hard benefits of both can be used for common plastic and can be used
for engineering plastics.
Uses: mainly cover packages for helmet shell helmet liner, and render EPS bonding or separately, mainly used in the limit of helmets, Ski Helmets on, types of rock climbing helmets, motorcycle helmets.
PC
Ingredients: PC is a comprehensive high performance amorphous thermoplastic resin.
Features: extension with excellent electrical insulation, resistance, dimensional stability and chemical resistance, high strength, heat resistance and cold resistance.
Uses: mainly cover packages for helmet shell helmet liner, and EPS solution synthesis of an organic whole renders, bicycle helmets, Ski Helmets, more rock climbing helmet use.
PVC
Composition: PVC is made by free radical polymerization of vinyl chloride monomer into polymer.
Features: disadvantages of PVC thermal stability is not good, process is not good, poor impact resistance, aging resistance and cold tolerance of difference.
Uses: mainly cover packages for helmet shell helmet liner, gluing and EPS forms, more at the low end of bicycle helmet use.
EPS
Ingredients: EPS commonly known as bubbles or styrofoam, is short for polystyrene.From raw materials through the advance, limestones, forming, made of dried and cut.EPS into white material and black material, housing and then a foam and foam.Black material costs more expensive than white material, density is higher than white;Foaming higher than secondary foam densities.EPS density, the higher the hardness is harder, the weight is heavier, while weak.
Features: light weight, mature technology, you can mass production-process, environmental protection, as the world's most popular material.
Uses: mainly used in the helmet liner made play buffer, shock, impact absorbing foreign.
EVA
Ingredients: EVA is ethylene-vinyl acetate copolymer, which is low-foamed polyethylene bubble plastic.
Features: EVA is a new type environmental protection plastics packaging, has a good cushion, seismic, heat insulation, moisture, and other advantages, with non-toxic, does not absorb water.
Uses:mainly used in the inside of the helmet liners more, water proof, anti-shock effects.
More drifting on a helmet and some of the limits of helmet use.
