Glastic® UTR

Glastic® UTR is one of our Glastic® laminates and offers a superior combination of electrical and mechanical properties. Made from fiberglass-reinforced thermoset polyester resins, these UL®-recognized sheets blend excellent performance characteristics with economy. The numerous property advantages of RGC laminates include:

Electrical Insulation

All electrical insulating laminates have inherently good dielectrics. The grades featured here have been engineered to maximize the specific properties required for a wide range of electrical applications.

Flame Resistance

UTR is UL-rated V-0 and is a halogen free system that generates very low smoke and smoke toxicity in a fire situation.

Mechanical Strength

High impact fiberglass-reinforced polyester laminates won’t shatter. Rigid laminates provide structural support as they insulate. Flexible laminates are available for applications that require a minimum bend radius of 19mm diameter.

Heat Resistance

Glastic® laminates offer excellent property retention and dimensional stability at elevated temperatures. These laminates have UL temperature index ratings from 120 – 210°C electrical, and from 130 –210°C mechanical.

Ease of Fabrication

These materials are easily fabricated with standard metal working equipment. They can be punched, drilled, machined, sheared and sanded. Grade UTR is well known for its ease of fabrication in high-speed machining centers.

Cost Effectiveness

In addition to significant property benefits, Glastic® laminates offer cost effectiveness over most high-pressure laminates. They outperform the phenolic grades and can often replace the more exotic epoxies and silicones at a considerable cost savings.
