Nema Grade G10 FR4 G11 tubing are made of alkali-free glass fabric and binded with epoxy resin, cast to specific sizes, and then molded or ground to desired specifications.
G10 FR4 G11 tubes also have excellent chemical and electrical resistance under dry and wet conditions.G10 FR4 G11 tubes also exhibit high flexural, impact resistance, excellent mechanical and bonding strength at temperatures up to 130℃.
Suitable for being used as insulation structural parts of mechanical, electrical and electronic equipment. Applications include mast, heat exchanger, coil and inductor.The G10 fiberglass tube is ideal for spacers and standoffs.G10 FR4 G11 tubes are also suitable for bushings.G10 FR4 G11 tubes are available in both standard and custom sizes.

FAQ:
Q:Is the g10 durable?
A:G10 material has the characteristics of insulation, corrosion resistance and wear resistance.The G10 is a composite made of fiberglass cloth and epoxy resin, originally developed as a material for aircraft that can withstand extreme forces without breaking and deforming.G-10 will not be permeated by water, gas, liquid, has the characteristics of insulation, acid and alkali resistance, weight is not heavy.
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:Is g10 waterproof?
A:G10 material has water resistance, but still has a trace proportion of water absorption, NEMA grade G10 water absorption ratio is less than 0.5%
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 is the difference between g10 and fr4?
A:G10 FR4 laminate grades are produced by inserting continuous glass woven fabric impregnated with an epoxy resin binder while forming the sheet under high pressure.G10 and FR4 have extremely high mechanical strength, good dielectric loss properties, both wet and dry. The main difference between NEMA Grades G10 and FR4 is that FR4 is a fire retardant grade of G10. Therefore, FR4 may be substituted where G10 is called out except in applications where halogens are not desired. G10 can never be substituted where FR4 is called for.
