Unsaturated Polyester Molding Compounds

Hexion’s unsaturated polyester molding compounds (UP-MC) feature good dimensional stability, outstanding insulating properties and are easy to color.

Electrical components meeting the most stringent demands on their tracking resistance can be easily produced. Self-extinguishing grades are used for electrical components such as:

Lighting fixtures
Switch gear
Contact bridges

Halogen and phosphorous free grades are also available. Specific grades are UL listed at the highest flame resistance class (V-0) at 0.8 mm and offer a 170°C electrical RTI (Relative Temperature Index). Visually attractive and dimensionally stable parts such as oven handles can also be achieved using a UP-MC material.
