Molded & cast urethane products are those which are covered in urethane, which is an adaptable kind of plastic material created from the chemical reaction of polyethers and polyesters diisocyanates. Molded & cast urethane products offer flexibility and fantastic chemical resistance. They can be used for a number of industrial purposes including pressure transducers, water treatment facilities, and petroleum products. Additives can be included to reduce friction, increase flame retardation, and improve UV resistance. Molded & cast urethane products can also be used for small devices like washers to meet specific requirements.

Urethane appears as a white crystalline powder. It must be converted to its liquid state for the reaction to occur. While it is relatively stable, it is incompatible with strong acids, bases, or oxidizing agents. Molded & cast urethane products are made when liquid state urethane is poured or injected into a mold containing the product. A reaction occurs and the urethane expands and hardens. It is sometimes necessary to cure the products in industrial ovens to ensure lasting quality. A dust collecting system can be helpful when working with these products.

While urethane can be an outstanding protective material for products such as items as small as wire or cases to items as large as residential homes, it can also be a very dangerous material. It is a recognized carcinogen, and it is hazardous to developing fetuses. Additionally, it is suspected to be toxic to the gastrointestinal system, liver, kidney, skin, and respiratory tract. It is, however, easy to prevent these dangers by wearing protective clothing and providing appropriate exhaust ventilation. It is also necessary to wash thoroughly after exposure. The risk of getting ill from urethane exposure is higher for industrial workers than residents of a community where urethane is processed, however if proper precautions are taken, adverse effects can be avoided. Furthermore, once urethane is processed into molded & cast urethane products, there are no health hazards.
