Molecular Structure

Functions
1. The ortho-diallyl bisphenol A is mainly used for the modification of bismaleimide, abbreviated as BMI. It can substantially reduce the application cost of BMI resin. Additionally, it can improve the operability and manufacturability of BMI resin. In detail, it can enhance the toughness, heat resistance, and film-forming property of BMI resin.
2. Furthermore, the O-DABPA is applicable for the electrical insulating materials, copper-coated circuit board, the high-temperature resistant dipping varnish, the insulating-paint laminated board, as well as the molded plastics, among others.
3. The ortho-diallyl bisphenol A also plays a role in wear-resistance materials, diamond wheel, heavy duty wheel, brake pads, the adhesive of high-temperature bearing, and more. In addition, it serves as the functional material as well as the aerospace structural material.
4. At last, the O-DABPA can act as the anti-ageing agent of rubber. By adding 1-3% of BBA into the rubber, the degree of ageing resistance of rubber can be significantly increased.

Packaging and Storage
1. The ortho-diallyl bisphenol A is wrapped in a drum. Each drum can bear 20kg, 50kg or 200kg of O-DABPA.
2. During transportation, this product must avoid rain shower or great pressure.
3. The product ought to be stored in a dry and ventilated warehouse. Additionally, it must leave far away from heat sources and fire sources, and prevent being exposed to sunlight.
