Q1: What is the difference between G10 and G11 materials?

G10 material is slightly better, while G11 material is a superior insulator capable of withstanding higher temperatures. G-11 and similar glass fiber reinforced thermosetting materials are sometimes referred to as Garolite.


Q2: What is G11 material?

G-11 glass cloth epoxy resin is a thermosetting industrial glass fiber composite laminate board. It is composed of continuous filament glass cloth material impregnated with epoxy resin adhesive. It is typically identifiable by its natural color, ranging from yellow-green to amber.


Q3: What colors are available for G11 material?

We offer yellow and water green colors.


Q4: How should G11 products be stored?

G11 products should be wrapped with packaging film, packed on a pallet, and stored horizontally in a dry and clean room at room temperature. They should be kept away from moisture and fire. The recommended storage period is 12 months.


Q5: Do you have certifications and samples?

Yes, we have obtained ISO9001, ISO 14001, and UL certifications. Samples for testing purposes are available.


Q6: Do you support customization?

Yes, we support customization. We can provide one-on-one customization based on specific requirements and ensure timely and quality processing of custom orders.
