Epoxy glass fiber board manufacturers introduce various indicators of epoxy glass fiber board

Analysis of the use and manufacturing process of epoxy glass fiber board:

Epoxy glass fiber board is an insulating product made of alkali-free non-twisted glass fiber yarn, non-twisted glass cloth, and wolan cloth impregnated with epoxy compound glue, and then heated and cured; it can be made into B grade, according to user requirements. Class F and H heat resistance grades, with good electrical performance and mechanical strength, are currently widely used in 35KV, 110KV, 220KV, 1000KV surge arrester sleeves and pole switch sleeves in the electrical porcelain industry.

Appearance of epoxy glass fiber board: The surface should be smooth and smooth, free of bubbles, oil and impurities, and color unevenness, scratches, and slight height inequality that do not hinder use are allowed. The epoxy glass fiber board with a wall thickness of more than 3mm is allowed to have end faces or cross-sections. Does not hinder the use of cracks.

The production process of epoxy glass fiber board can be divided into four types: wet rolling, dry rolling, extrusion and wire winding.
