White PP Plastic Rods

Polypropylene (PP) - This polyolefin is readily formed by polymerizing propylene with suitable catalysts, generally aluminum alkyl and titanium tetrachloride. Polypropylene properties vary according to molecular weight, method of production, and the copolymers involved. Generally polypropylene has demonstrated certain advantages in improved strength, stiffness and higher temperature capability over polyethylene. Polypropylene has been very successfully applied to the forming of fibers due to its good specific strength which is why it is the single largest use of polypropylene. Polypropylene also happens to be one of the lightest plastics available with a density of 0.905 g/cm²

PP properties:

• Excellent resistance (no attack) to dilute and concentrated Acids, Alcohols, Bases and Mineral Oils
• Good resistance (minor attack) to Aldehydes, Esters, Aliphatic Hydrocarbons, Ketones and Vegetable Oils
• Limited resistance (moderate attack and suitable for short term use only) to Aromatic and Halogenated Hydrocarbons and Oxidizing Agents 

The details about PP:

1.Tensile Strength: 4,500 psi

2.Specific Gravity: 0.90

3.Melting Point: 338°F 170°C

4.Translucent 

5.Hardness: R95
