GNS ALL PURPOSE PU FOAM A40 is a one-component, economical type and good performance Polyurethane foam. It is fitted with a plastic adaptor head for use with a foam application gun or a straw. The foam will expand and cure by moisture in the air. It is used for a wide range of building applications. It is very good for filling and sealing with excellent mounting capacities, high thermal and acoustical insulation .

750ml/can, 500ml/can,12pcs/ctn for both Manual type and Gun type.
Gross weight is 350g to 950g upon requested.

Q: If the PU foam shrinks after curing, what effect will it bring?
A: It will damage doors and windows and the performance of PU foam will be reduced.
Q: Why should we choose a PU foam with good elasticity?A: Because the PU foam with good elasticity will not damage the doors and windows in hot weather, because its structure inside is better.
