Protection components of a RHINO series boot: composite toe cap, non-metallic midsole, antistatic body

PU Technology

Why Polyurethane?

Polyurethane is selected for its combination of low weight, flexibility, insulation and resistance. We select the toe cap, midsole and inner lining according to working conditions.

  • The outsole varies by family: polyurethane on GRANOX and RHINO PU/PU, TPU on RHINO PU/TPU, rubber on RHINO-R.
  • Toe cap (steel or composite), midsole (metal or non-metallic), outsole (PU, TPU, rubber) and lining are determined separately.
  • Production: German DESMA direct injection line.
