How Sondor assists the Marine and Floatation Industries 

Sondor, industrial foam suppliers, has been assisting the Maritime Industry for over 70 years. With solutions to assist with floatation, soundproofing, and multiple other applications, you will be insulated, comfortable, and buoyant with us. 

Closed cell foam is an ideal product to use for buoyancy, and Sondor SPX and SVA closed cell foam is ideal for this purpose. A boat's job is to float. SAMSA requires that all boats must consist of either foam or approved plastic bottles, or a combination of both. Buoyant material may not be affected by oil or oil products. The foam should be of a suitable closed cell type. Sondor has the solution for you!
