Product instruction

Silicone G7 laminated glass cloth Sheet is a high-performance insulating material, mainly made of glass cloth reinforcement and silicone resin laminated by hot pressing. It has excellent electrical insulation performance, high temperature resistance and flame retardant properties, and can work stably even in high humidity or high temperature environments.

1. Main performance characteristics ：

High temperature resistance: can be used in high temperature environment of 200~220℃ for a long time

Stable electrical performance: excellent insulation even in humid and high temperature conditions

Good flame retardancy: self-extinguishing performance

Strong chemical stability: acid and alkali resistance, aging resistance

Good dimensional stability: low thermal expansion coefficient, structure is not easy to deform

2. Comparison between G7 and other glass cloth sheets:

Type	Resin Base	Temperature Resistance	Flame Retardancy	Typical Environment
G7	Silicone	200–220°C	Excellent	High temp / Humid
G10	Epoxy	130–150°C	Moderate	General purpose
G11	Modified Epoxy	~180°C	Good	High temp
FR4	Flame-retardant Epoxy	~130°C	Excellent	General electronics

3. Typical uses of G7 laminated glass cloth sheet:

High temperature electronic/electrical insulation

Application scenarios: insulation parts of motors, transformers, generators, and electric heating equipment.

Advantages: long-term temperature resistance up to 180°C~250°C (H grade or higher insulation grade), good flame retardancy (UL94 V0 grade), suitable for high temperature and high humidity environment.

Aerospace and military industry

Application scenarios: aircraft engine compartment insulation layer, missile fairing, spacecraft circuit substrate.

Advantages: lightweight, heat shock resistant, stable performance at extreme temperatures (-60°C to +300°C).

 Rail transit

Application scenarios: electrical control systems of high-speed rail/subway, traction motor insulation boards.

Advantages: flame retardant, low smoke and non-toxic, in line with rail transit fire protection standards such as EN45545.

New energy and power equipment

Application scenarios: insulation support parts of solar inverters, wind power converters, and high-voltage switch cabinets.

Advantages: arc resistance, corona resistance, high dielectric strength (>20kV/mm).

Chemical and anti-corrosion equipment

Application scenarios: reactor lining, pipeline sealing gaskets, structural parts in corrosive environments.

Advantages: acid and alkali resistance, organic solvents and ozone resistance, excellent anti-aging performance.

High-end electronic packaging

Application scenarios: high-frequency PCB substrates (such as radar, 5G communication equipment), high-power LED heat dissipation substrates.

Advantages: low dielectric constant (Dk), low dielectric loss (Df), stable high-frequency signal transmission.
