How are Thermoplastic Additives used?
They are applied to increase the fracture toughness of epoxy resins. Only relatively low MW TPs can be dissolved in epoxy resins. Commonly used thermoplastics are phenoxy, polyether block amides, PVB, polysulfone, polyethersulfone, polyimide, polyetherimide, nylon.
As compared to rubbers, thermoplastics are more effective tougheneres in highly cross-linked matrices and they do not tend to influence Tg and modulus.
However high loadings of TP lead to increase in solvent sensitivity and decreases resistance to creep & fatigue.
