Properties of polyurethane foam
Under the influence of humidity of air foam increases in the volume on 50 … 250. It will be polymerized (stiffens) quickly. A necessary condition for work with foam is temperature from 5 to 35 °C in the summer and from-10 to 30 °C in the winter. In each case humidity has to be not less than 35%, otherwise foam does not harden.
Foam possesses good adhesion (coupling) to the majority of all-construction materials, except polyethylene, polypropylene, teflon, silicone, wax. It also provides high acoustic and thermal isolation, after hardening is water-proof.
High penetration provides filling of cracks and cracks. In the stiffened look keeps elasticity, resilience on mechanical influence.
Very important before foam use carefully previously to shake up a cylinder.
