Polyimide materials represent one more significant area where chemical selection forms end-use performance. Polyimide diamine monomers and polyimide dianhydrides are the key building blocks of this high-performance polymer household. Relying on the monomer structure, polyimides can be made for flexibility, warm resistance, openness, low dielectric constant, or chemical resilience. Fle... http://karayaz.ru/user/crowdplier62/
