Why is PP resistant to Diesel Fuel?
PP shows excellent resistance to Diesel Fuel due to its semi-crystalline structure providing good chemical resistance to acids, bases, and organic solvents at moderate concentrations.
⚠️ When NOT to use PP
Avoid using Polypropylene with concentrated oxidizing acids, chlorinated solvents, and aromatic hydrocarbons. Becomes brittle below 0°C.
