Blister board is an amorphous, odorless, non-toxic, highly transparent colorless or yellowish thermoplastic engineering plastic, with excellent physical and mechanical properties, especially excellent impact resistance, high tensile strength, bending strength and compressive strength; Low creep and dimensional stability; It has good heat resistance and low temperature resistance, stable mechanical properties, dimensional stability, electrical properties and flame retardancy in a wide range of temperatures, and can be used for a long time at -60~120 °C; There is no obvious melting point, and it is in a molten state at 220-230 °C; Due to the rigidity of the molecular chain, the viscosity of the resin melt is large; Small water absorption, small shrinkage, high dimensional accuracy, good dimensional stability, and small air permeability of the film; It is a self-extinguishing material; Stable to light, but not resistant to ultraviolet light, good weather resistance; Oil-resistant, acid-resistant, intolerant of strong alkalis, oxidizing acids and amines, ketones, soluble in chlorinated hydrocarbons and aromatic solvents, easy to cause hydrolysis and cracking in water for a long time, the disadvantage is that due to poor fatigue strength, it is easy to produce stress cracking, poor solvent resistance, and poor wear resistance.
