FR4 G10 G11 Glass Epoxy Gasket Washer

FR4 sheet is one kind of epoxy sheet, "fr" is the abbreviation of "flame retardant", and fr4 sheet is the flame retardant material which meets the grade of "fr4". fr4 sheet is heat and moisture resistant, insulating and flame retardant, and has good mechanical and dielectric properties. Heat and moisture resistance, insulation and flame retardant, and has good mechanical properties and dielectric properties, commonly used in circuit boards, a variety of switches, drilling pads and other production.

What is fr4 sheet?

fr4 sheet is epoxy board (epoxy resin board) of a kind, is made of epoxy resin organic polymer compounds and glass fibers made of composite materials. The "fr" is the English abbreviation for "flame retardant", and fr4 sheet is a material that meets the "fr4" flame retardant rating.

There are many colors of fr4 sheet, such as white, black, green, blue and so on.

1、Characteristics of fr4 sheet

The surface of fr4 sheet is smooth and flat, and heat-resistant, moisture-resistant, mold-resistant, acid and alkali resistant, impact-resistant, and its mechanical properties, dielectric properties and processing performance is good. The electrical properties in the dry and wet state are also excellent, the most important thing is that it has a very good flame retardant, small influence by the environment, the size is very stable.

2. fr4 sheet applications

I. Electronic and electrical field

Epoxy board has excellent heat resistance, corrosion resistance and flame retardancy, often used in the manufacture of printed circuit boards (PCB), insulators, transformers, motors and other electronic and electrical components. Epoxy boards have excellent chemical properties and good insulating properties, so they can carry very small size components in circuit boards. In addition to PCBs, epoxy boards are also widely used in the manufacture of LED lights, solar panels and other electronic products.

Second, the field of mechanical processing

Epoxy board is a kind of high-strength, high adhesion material, with pressure resistance, bending resistance, wear resistance and other characteristics. It is widely used in mechanical processing, such as machine tools and other high-precision machine processing surface. In addition, epoxy board can be used to make jigs, molds, templates, etc., with strong compression and abrasion resistance.

Third, building decoration field

Epoxy board is also widely used in the field of building decoration. Because of its fire resistance and corrosion resistance, it is often used to make underground garage, hydraulic station, food factory and other epoxy ground. In addition, epoxy board is also used for waterproof coating, which can make the building with waterproof, moisture-proof, non-slip and other properties.

Fourth, bicycles, ships and other fields

Epoxy board is usually used to make brackets and other parts for bicycles, ships and so on. It has high strength, corrosion resistance, friction resistance and other characteristics, and is considered a durable and reliable material.

In short, epoxy sheet is an excellent material with a variety of powerful properties. It is widely used in electronic and electrical appliances, machining, construction and decoration, bicycles, ships and other fields, bringing more convenience and benefits.
