Product Description
Product Description
Composition FR4 (Flame-Retardant 4) is a composite material with glass fiber cloth as reinforcement material and epoxy resin as matrix, and is laminated through high temperature and high pressure process. Its core components include: Glass fiber cloth: provides mechanical strength and dimensional stability, and the woven structure enhances impact resistance. Epoxy resin: As an adhesive, it gives the material flame retardancy (UL94 V-0 grade) and chemical corrosion resistance. Flame retardant additives: ensure that the material self-extinguishes when burning and meets safety standards.
Electrical insulation: high insulation resistance, low dielectric constant, suitable for high-frequency circuits.
Mechanical strength: high bending strength and impact resistance.
Heat resistance: can remain stable at higher temperatures, usually 130°C to 140°C.
Flame retardancy: meets UL94 V-0 flame retardant standards and has good fire resistance.
Chemical resistance: good resistance to most chemicals.
Dimensional stability: can remain dimensional stable under changes in temperature and humidity.
Advantages
High performance: excellent electrical and mechanical properties, suitable for demanding applications.
Flame retardancy: meets strict flame retardant standards and is highly safe.
Versatility: suitable for a variety of electronic and electrical applications.
Processability: easy to cut, drill and surface treat.
Environmental protection: some products comply with environmental protection standards such as RoHS.
