Poly S is the itwc designation for polyester. It is followed by the molecular weight and the additonal letters identify the type of polyester. For example, Poly S 1000EBA is a 1000 molecular weight ethylene/butylene adipiate.
Polyesters are often selected for urethane applications when abrasion resistance and resistance to grease and oil are important requirements for the success of a finished product.
