Material & shape of the helmet shell



Thermoplastic HDPE, high-density polyethylene, Straight helmet shape with gutter

  • Thermoplastic material, available in pellet form, is heated into a plastic state and turned into the required helmet shell shape using an injection moulding tool.
  •  Material ageing through exposure to UV radiation and other environmental influences cannot be excluded.
  • The German Accident Prevention & Insurance Associations generally recommend that helmets made of thermoplastic material (HDPE and ABS) should be used for no more than 4 years.
