Applications

Polyether SG35 is suitable for cushions and other applications that are not used intensively on a daily basis. It is resilient, flexible, and offers good support — but has a shorter lifespan compared to foams designed for heavy, everyday use.

Forming

After shipping, the foam usually needs one day to return to its original shape and size.
