How can I distinguish the safety helmet of ABS and GRP?
Each of these two has its merits. The use of different venues, for example, steel plants to choose glass fiber, ABS encountered high temperatures will become soft.
Very simple, with a lighter burning, can soften the ABS, and can not soften the glass fiber reinforced plastic.
The easiest way is to knock with your hands. ABS sounds so small that there is almost no response, and the material is relatively soft. The sound of FRP is loud, crisp and hard.
Glass steel material, high temperature resistance, corrosion resistance, not easy to deformation, stress than ABS good quality, a long period of use, ABS is a kind of chemical raw materials, also belong to the type of plastic, plastic strength than ordinary high strength, impact resistance.
