AI Technical Summary
Existing protective headgear is bulky, uncomfortable, difficult to integrate, and may contain toxic materials. Furthermore, the energy-absorbing material is either too thin or too rigid, resulting in insufficient protection.
Energy-absorbing materials, made from foaming agents containing styrene-based thermoplastic elastomers (TPS) and expandable microspheres, are prepared by compression molding or injection molding processes. The material thickness ranges from 1 mm to 10 mm, and the Shore hardness ranges from 28 Shore 00 to 80 Shore A. It is suitable for use in protective headgear.
It offers lightweight, comfortable, and efficient energy absorption. The material maintains high energy absorption characteristics at a low thickness, is easy to integrate into the headgear, does not contain toxic substances, and is durable.
