How to Select Between the Grades

G10 and G11 epoxy glass sheets are widely recognized export grades for customers who need reliable insulation and structural performance. G10 is suited to general high-strength insulation use, while G11 is positioned for higher thermal demand and more severe operating environments.

Material and Grade Overview

MaterialEpoxy glass cloth laminate sheet Grade FocusG10 for balanced use, G11 for higher heat resistance Key FeaturesStrength, low water absorption and machining stability Export PositioningCommon equivalent material for industrial replacement and selection

Selection guide

Buyer questions to resolve before quotation

When should G10 and G11 be evaluated separately?

Evaluate them separately when service temperature, retained mechanical performance, electrical duty, moisture exposure, or a customer standard is decisive. A family name alone is not a substitution rule.

Which standard designation should appear on the quotation?

State the exact requested NEMA, IEC, or customer specification and revision, plus any cross-reference being proposed. The quotation should not rely on an unexplained “equivalent” label.

Which data should be compared before approving a grade?

Compare temperature classification, flexural and impact performance, dielectric strength, insulation resistance, water absorption, dimensional stability, and machining requirements using matched test methods.

What should be confirmed before ordering sheets or machined parts?

Confirm grade, thickness, sheet or finished dimensions, tolerance, color, surface finish, machining drawing, quantity, inspection documents, samples, packaging, and destination.
