Description of the use conditions of epoxy glass fiber board

Epoxy glass fiber board, epoxy phenolic laminated glass cloth board, epoxy resin generally refers to organic polymer compounds containing two or more epoxy groups in the molecule, except for some, their relative molecular masses are not high. The molecular structure of epoxy resin is characterized by the active epoxy group in the molecular chain. The epoxy group can be located at the end, in the middle or in a cyclic structure of the molecular chain. Because the molecular structure contains active epoxy groups, they can undergo cross-linking reactions with various types of curing agents to form insoluble and infusible polymers with a three-way network structure. The epoxy glass fiber board of this product is made by heating and pressing with epoxy resin. It has high mechanical performance at medium temperature and stable electrical performance under high humidity. It is suitable for high-insulation structural parts for machinery, electrical appliances and electronics, with high mechanical and dielectric properties, good heat resistance and moisture resistance, and heat resistance class F (155 degrees).

1. The operating temperature of epoksidna staklena vlakna board is 120 degrees Celsius. It can be used in an environment of 130 degrees Celsius in a short time. If it exceeds this temperature, it will warp, crack and become unusable.

2. It has good electrical properties, with a dielectric strength of 1000V/MIL and a breakdown voltage of 65 kV, which can work continuously in a high voltage and current environment.

3. It has strong machinability, good mechanical ability, compressive strength of 303 MPa, tensile strength of 269 MPa, bending strength of 455 MPa, and shear strength of 130 MPa. It can withstand strong impacts from the outside world and has good toughness.

4. The chemical properties are also good, with a certain degree of corrosion resistance.

5. It is non-flame retardant, non-bromine, in line with EU standards, environmentally friendly, and will not pollute the environment. It is used more abroad.

It can be seen from the above that the performance of epoxy glass fiber board is very good. It is made of glass fiber sheet woven with continuous filaments bonded with epoxy resin. It can be customized directly according to customer requirements. If the processed parts are processed, please refer to drawings Processing.
