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.
