Construction foam

Dimethyl ether is one of the most widespread propellants in production of polyurethane construction foams, since it enables manufacturers to complete two tasks at the same time: both propellant and solvent are injected at the same time.

The advantages of DME use:

• co-propellant;
• good solvent for the fluoropolymer;
• extends shelf life of the final product;
• regulates foam viscosity and structure;
• formulation with DME allows to optimize winter compositions.
