Polyurethanes
Polyurethanes
Polyurethane also come in a more rigid material, normally defined in terms of the Shore D hardness.
They are either solid or foamed. In the instance of the foaming Polyurethane, these come in various densities that can either be used to cast or for spray application.
We also display our flexible urethanes, however this is explained in a different booklet for Casting and crafting industry.
Foaming rigid foams can be used as buoyancy aid, insulation materials, packaging, etc.
NB do not use low-density foam for buoyancy in boats as can absorb water easily (best to be 60 or greater densities).
