HIGH YIELD, SELF-EXPANDING PU FOAM
PU foams are one-component, easy-to-use PU foams that are applied either through PU foam guns (gun foams) or through included manual straw applicators (straw foams). Once extruded from the applicator, PU foams expand in size through reactions with moisture in the environment. When fully cured, PU foams are semi-rigid with resistance to water and chemicals, making them an ideal product for sealing and filling large voids and gaps with a requirement of durability.
Fully-cured PU foam is made of millions of tiny cells – these cell structures give foams excellent insulation properties, and make PU foams a superb product for applications where thermal and acoustic insulation of the gap filler is desired, such as for the filling of gaps between wall and window-frame.
Its self-expansion properties make PU foams a high-value proposition. Each 750 ml can of foam can achieve up to 60 litres of cured foam.
WHAT WE PROVIDE?
All PU foams need to achieve a delicate balance between density, yield, and strength. Too dense, and you have poor insulation and poor yield, bringing poor value. Not dense enough, and your foams face a risk of collapsing and having poor durability.
Achieving a right open-cell formulation takes years of work and research to perfect, because it’s such a delicate process. As a professional PU foam filling machines manufacture, from many years of experience in helping customers plant establishment, in-door installation, equipment debugging, technical training, we has developed its proprietary formulations and manufacturing processes of PU foams. A very strong PU foam that combines medium density with open cells that strikes all the right balances in achieving high yield, high strength, and high durability.
