Rigid PUR foam (single components)

Технические характеристики

Two-component foam resin

• Closed-cell, hard
• Low density with good compressive strength
• Very short curing time
• Contains flame retardants, so suitable for boats

Rigid PUR foam yields a closed-cell rigid polyurethane foam and so its capacity to absorb water is very low. As a result, it is ideal for foaming cavities not only in the boatbuilding and automobile sectors, but also in other sandwich structures, including low-temperature and heat insulation.

Mixing ratio:
100 : 144 parts by weight of PUR-Foam to hardener 1000
