Flat Sheet Laminate

Röchling Glastic laminates offer a superior combination of electrical and mechanical properties such as dielectric strength, flame resistance, arc and track resistance, high-flexural strength and high-impact strength.

These sheets are fiberglass-reinforced thermoset polyester. They will not melt under heat and have excellent overall electrical properties. All grades are UL® recognized.

Our laminates also have superior consistency in thickness, punchability and property control. Add a high degree of quality and cost-effectiveness, and it is no wonder that Röchling Glastic laminates have helped make us a leader in composite materials.

Electrical Insulation
All Röchling Glastic Composites electrical insulating laminates have inherently good dielectrics. They are engineered to maximize the specific properties required for a wide range of electrical applications.

Flame Resistance
Grades 1580 and UTR are UL-rated V-0. Grade UTR is a halogen-free system that generates very low smoke and smoke toxicity in a fire situation.

Mechanical Strength
Our high-impact fiberglass-reinforced polyester laminates won’t shatter and provide structural support as they insulate. Flexible laminates are available for applications that require a minimum bend radius of 0.75" diameter at 1/32" thickness.

Heat Resistance
Röchling Glastic Composites laminates offer excellent property retention and dimensional stability at elevated temperatures. These laminates have UL temperature index ratings from 120˚C to 210˚C electrical, and from 130˚C to 210˚C mechanical.

Ease of Fabrication
These materials are easily fabricated with standard metalworking 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. Grade 1580 punches cleanly and quickly.

Cost Effectiveness
In addition to significant property benefits, these 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.

Sheet Sizes
Röchling Glastic laminates are available in the following sizes: 49-3/8'' x 96'', 36'' x 72'', and 48'' x 60'' in thicknesses from 1/32” to 2” and .8mm to 60mm. Custom lengths are available in 4' widths.

Custom Grades
Custom grades of laminates and colors are available. Please contact us for more information.
