FAQ:
Q:What is fr4 material?
A:Fr-4 Little green/yellow/black sheet is a rigid insulation material made of imported alkali free glass fiber cloth impregnated with imported epoxy ester resin and added with imported flame retardant and adhesive.
Q:What is Garolite used for?
A:Plastic G-10 / FR4 (GAROLITE) is a thermosetting epoxy resin sheet, bakelite and glass fiber material.With good electrical insulation, chemical corrosion resistance, high temperature resistance, moisture resistance, hydrolysis resistance, widely used in the electrical industry, the most is to make circuit plate.
Q:What is the difference between g10 and Micarta?
A:G10 is made of multi-layer woven glass fiber and epoxy resin. Like G10, Micarta is made of multi-layer woven material and epoxy resin layer. However, Micarta is not made of woven fiberglass, but of natural fabrics such as canvas, linen, paper, or burlap. What is certain is that the cost of G-10 is cheaper than that of Mikata, and G-10 is easier to customize and process.
Q:What are fiberglass tubes?
A:Fiberglass tube is a kind of pultrusion formed FRP composite material, which is a thermosetting elastic material formed by continuous fiberglass coarse sand and resin under the traction of pultrusion molding machine.The rich resin layer on the surface makes it have good anticorrosion.Common fiberglass tubes include FR4 G10 G11 3240 tubing.
Q:What color is g10?
A:The Natural color is Light Green,and common colors include yellow and black.But customized colors are available.
