G10 Filament Wound Tube
It is a common choice for engineers and manufacturers in applications requiring stringent material strength, insulation performance, and environmental resistance.
Welcome to Learning about G10 Filament Wound Tube
The G10 filament-wound tube is made of high-quality fibreglass impregnated with ultra-low-viscosity, high-temperature-resistant epoxy resin by winding. It offers outstanding chemical and electrical resistance in both dry and wet conditions. The G10 filament-wound tube is a great insulator with almost minimal water absorption and exceptional dimensional stability, which is why it is so popular in the electronics sector.
Filament epoxy-wound tubing is made using a rigorous manufacturing process that guarantees consistent and dependable product quality. It is a reliable option suitable for engineering tasks requiring high durability and strength.
What is the difference between G10 and FR4?
G10 is distinguished by its superior mechanical and electrical qualities, although it lacks flame retardancy. FR4 can obtain a UL94 V-0 grade for flame retardancy by adding flame retardants to G10; however, doing so raises costs and might slightly weaken some mechanical qualities.
All in all, G-10 is closely related to FR-4 glass epoxy, but FR-4 is fire retardant.
Advantages
According to NEMA (National Electrical Manufacturers Association) standards, G10 is a laminated material made of continuous glass fibre reinforced with epoxy resin and then cured under high temperature and pressure. After being processed into a tube using a winding process, the G10 filament-wound tube offers the following core advantages:
High mechanical strength
Excellent resistance to bending, compression, and impact.
Excellent electrical insulation
Stable insulation resistance in high-humidity environments.
Low water absorption
Withstands humid environments and chemical corrosion.
Good dimensional stability
Minimal deformation with temperature and humidity fluctuations. At present, this tube is widely used in transformer skeletons, switch equipment, robotic arms, and measurement equipment.
Applications
G10 filament-wound tubes are used in many industries, such as bolt protection, chemicals, the military, medicine, and electrical.
