Polypropylene Rod（PP Rod）
1.weight & Durable：Low density (0.90~0.94 g/cm³), making it easy to machine and transport.
Excellent fatigue resistance, suitable for repeated bending and impact.
2.Chemical Resistance：Resistant to most acids, alkalis, salts, and organic solvents (e.g., alcohols, aldehydes).
Not suitable for strong oxidizing acids (e.g., concentrated sulfuric acid, nitric acid) and some halogenated hydrocarbons.
3.Temperature Resistance：Operating range: -10°C to +100°C (short-term up to 140°C). Becomes brittle at low temperatures.
4.Electrical Insulation：High resistivity, ideal for electrical insulation, especially in high-frequency environments.
5.Mechanical Properties：Good rigidity but lower wear resistance than nylon (PA). Can be reinforced with glass fibers.Smooth surface with low friction coefficient, suitable for low-load sliding parts.
6.Non-Toxic & Food Safe：Some grades comply with FDA standards for food and medical applications.
7.Ease of Machining：Can be cut, drilled, turned, and welded (hot plate, ultrasonic welding).
