As a result the terms urethane and polyurethane are used interchangeably. Polyurethane is also very flexible and it lasts a long time.

Removing the chlorine seems to remove some of the voc off gassing risk but it doesn t remove all the safety questions. All polyurethane coated fabrics are made from polymer resins. There are three basic types of resins used in making polyurethane coated fabrics. When i was shopping.

The transfer of odors or taste to products flowing within. Although these types of vinyl are free of chlorine they still may contain chemicals that are better avoided. Polyurethane can be safe but do your research. When the resins and hardeners are combined they form a chemical reaction which results in a.

Finally our pu coated gloves are the polyco dyflex ultra cut resistance gloves which in true polyurethane fashion offer superb grip in oil grease and water offer superb comfort and provide a high level of flexibility they are ideal for gripping wet and oily tools working with equipment and operating machinery where their impressive cut resistance.
