Introduction to Polysebacic Anhydride (PSPA)
Polysebacic Polyanhydride (PSPA) is an excellent cracking-resistant toughening curing agent with a low melting point, low toxicity, moderate viscosity, and excellent compatibility with a wide variety of epoxy resins. The cured substances have good thermal-state, electrical, and mechanical properties, especially the excellent resistance to cold and heat impact. It is widely used in all kinds of household appliances, electromechanical and electronic devices, national defence industry, etc.
Main Ingredient: long carbon-chain aliphatic polycondensated anhydride of dibasic acid
