PPC plastic, also known as poly propylene carbonate, is a fully degradable environmental protection plastic synthesized from carbon dioxide and propylene oxide.
Poly propylene carbonate is soluble in polar solvents such as lower ketones, ethyl acetate, dichloromethane and chlorinated hydrocarbons, but is insoluble in solvents such as alcohols, water and aliphatic hydrocarbons. It also forms a stable emulsion in water. PPC does not allow gases such as oxygen to diffuse through it. The glass temperature (Tg) is between 25 and 45°C, and the PPC adhesive is amorphous. The glass temperature of PPC is slightly higher than that of polyethylene carbonate (PEC). Its refractive index is 1.46 and its dielectric constant is 3.
Polypropylene carbonate is used to increase the toughness of some epoxy resins. It is used as a sacrificial binder in the ceramic industry, decomposing and evaporating during the sintering process. It has a low sodium content, making it suitable for the preparation of dielectric materials and piezoelectric ceramics and other electroceramics. The composite material of polycarbonate and starch (PPC/starch) is used as a biodegradable plastic.
