CAS NO 127667-44-1 Bisphenol M cyanate ester

Features:

It is light yellow semi-solid or white powder crystal at room temperature. It can be polymerized to prepolymers or oligomers. Cured polymers have lower moisture absorption, better dielectric properties and higher fracture toughness.

Applications:

Aerospace, composites, electronic circuitry, stealth and low observables, etc.

Packaging and Storage:

Please store in a cool, ventilated, dry place and keep away from heat source.

18 months at room temperature(25℃), 24 months at temperature ≤5℃ in keeping original package.
