Characteristics of Glass Epoxy Sheet G10 / G11:
1. Composition of the Material: Woven glass fabric impregnated with epoxy resin makes up G10 and G11. The composition of the glass fabrics in the two classes is what distinguishes them most from one another. While G11 makes use of a high-temperature glass fabric, G10 uses a regular glass fabric.
2. Insulation against electricity: G10 and G11 both have excellent electrical insulating qualities. They are suitable for use in applications where electrical isolation and dependability are essential due to their high dielectric strength.
3. Resistance to Temperature: G10 can withstand high temperatures well, usually up to 130 - 150 deg C (26 - 302 deg F). G11, on the other hand, can often endure temperatures of 180 - 200 Deg Centigrade. Due to the differential in temperature resistance, G11 is better suited for applications requiring greater heat resistance.
4. Strength mechanical: Both grades show good dimensional stability and mechanical strength. With minimal distortion or breaking, they can tolerate mechanical stress, vibration, and physical impact.
5. Resistance to Chemicals: G10 and G11 are suited for use in locations where exposure to corrosive substances may occur since they are resistant to various chemicals, including acids and solvents.
6. Flame-retardant: They are made with self-extinguishing capabilities and are flame retardant by design. As a result, they inhibit combustion and wont aid in the spread of fire, improving safety in a variety of applications.
7. Reduced Water Absorption: Due to their minimal water absorption, both grades can withstand prolonged exposure to moisture without losing their mechanical or electrical performance.
8. Flexibility: G10 and G11 are adaptable materials that have a variety of uses, including as electrical insulators, structural elements, bushings, gaskets, and other parts in the aerospace and maritime industries.
9. Manufacturability: Using common equipment and methods, they are easily machined, cut, drilled, and shaped, enabling exact customization to satisfy particular design needs.
10. Environmental Points to Consider: Due to the epoxy resin component, G10 and G11 are not naturally eco-friendly, but correct handling and disposal are crucial to reducing their negative effects on the environment. Recycling and proper garbage disposal are crucial factors to take into account.

FAQs of Glass Epoxy Sheet G10 / G11:
Q: How are G10 and G11 glass epoxy sheets manufactured?
A: G10 and G11 sheets are produced using a hot pressing technique where epoxy resin and E-glass fiberglass cloth are laminated together under heat and pressure. This process ensures a dense, uniform, and dimensionally stable sheet with superior insulation and mechanical properties.
Q: What benefits do G10/G11 sheets offer for electrical and mechanical applications?
A: These sheets provide high dielectric strength, excellent insulation, low thermal conductivity, and robust mechanical strength. Their heat resistance (up to 130C for G10 and 180C for G11) and polished finish make them ideal for demanding uses in PCB supports, transformers, motors, and aerospace parts.
Q: Where can glass epoxy sheets G10/G11 be used?
A: Glass epoxy sheet G10/G11 finds utility in a broad range of applications, including transformers, electrical motors, circuit boards, shipbuilding, aerospace, defense, automotive sectors, and as base supports in PCBs and electrical components.
Q: When should I choose G10 vs G11 grade sheets?
A: G10 sheets are recommended for standard electrical insulation and mechanical support up to 130C, suitable for general electronics or electrical machinery. G11, with a higher thermal resistance of up to 180C, is ideal for applications involving higher operating temperatures, such as aerospace and industrial systems.
