EPS (expanded polystyrene) – EPS is also a plastic material. CGPRO uses only EPS of high quality with a density making the helmet perfect for impact absorption and long lasting. EPS is the inner liner and the main part for impact absorption in a helmet.
Inmold PC shell fused together with EPS liner in one operation created by pressure, heat and steam. PC shell is vacuum formed to the correct shape before inmold process. Inmold has the advantage in the light weight achieved, and protection is fulfilled through the force spread characteristic offered by the PC/EPS fusion: by impact from outside the impact forces are spread over a larger area of the human skull, reducing the risk of injury.
The finished EPS foam is made of numerous expanded small EPS beads, when the beads are heated with steam, the expanding agent begins to boil, the styrene softens and the beads expand. The EPS raw material is imported from America, Japan or Austria.
