Application:
It is principally used in the modifier of Bismaleimide(BMI). It can reduce the applying cost of BMI resin greatly, improve its operation and techics, and improve its tenacity, heat-resistance and model forming. BMI can be used in 1).electrical insulation materials,insulated lacquer, high temperature resistant varnish of circuit board with copper coated, layered board, model plastic etc. 2).friction-resistant material, diamond grinding wheel, heavy-burdened grinding wheel, brake slice, high temperature resistant adhesive of axletree etc. 3).transverse spaceflight configurable material. 4).functional material.
As an age-resistance of rubber, it can improve its age-resistance greatly with 1-3% BBA added.
Diallyl bisphenol A / Diallyl ether of bisphenol A is a kind of modified monomer of thermosetting resin which is mainly used in the modifying and toughening of bismaleimide resin, epoxy resin, phenolic resin etc., it can enhance the toughness of thermosetting resin greatly .It also can be used as activity diluent of thermosetting resin, it is used in rubber, the adhension strength between metal can be further improved.
