Polyether SG40

Flexible, resilient, and suitable for intensive use

Polyether SG40 is a flexible and resilient foam rubber. When compressed, it quickly returns to its original shape. This type of foam is also referred to as foam rubber or polyether foam.

The SG-value (density) indicates that one cubic meter of this foam weighs 40 kg. The higher the SG-value, the longer the lifespan and the better the weight distribution.

Ideal for cushions and mattresses used daily

Polyether SG40 is highly suitable for applications that are used intensively and on a daily basis, such as cushions and mattresses.

The foam offers thermal insulation and is hypoallergenic, making it a hygienic and comfortable choice.

For lighter use, Polyether SG25 (for occasional use) and SG35 (for moderate use) may be more appropriate.
