Description
PP is a semi-crystalline thermoplastic with the low density (0.9 g/cm³), excellent resistance to acids and alkalis, and low cost. However, it exhibits brittleness at low temperatures, which can be improved through copolymer modification.
Key Features
1. Chemical resistance (it is resistant to acids, alkalis, and organic solvents) 2. Low density and high rigidity (ideal for lightweight applications) 3. Good insulation properties (excellent dielectric performance) 4. Poor UV and low-temperature resistance (additives for improvement required)
