Polypropylene
Polypropylene combines high corrosion resistance, high temperature resistance, and great tensile strength. It maintains its stiffness at elevated temperatures and displays incredible resistance to organic solvents, de-greasing agents, and electrolytic attack. In addition, the material is lightweight, and stain and moisture resistant.
Polypropylene is used where you need:
- Self Lubricating and Low Co-Efficient of Friction
- High Chemical Resistance
- Abrasion, Moisture and Electrical Resistance
- Stiffness, Rigidity, or Cut Resistance
- Low Specific Gravity (Floats in Water)
*

Material is used…
in many applications where chemical resistance and stiffness are a must.
- Resistant to 180°F and handles acids, alkalies and solvents extremely well.
- USDA and FDA approved for use in food processing applications.
- Excellent stiffness and rigidity
- Very good Dielectric Properties
- Impact and Stress Crack Resistant
- FDA and NSF Compliant
Due to its chemical resistance, Polypropylene is ideally suited to be used with a wide range of chemicals. Its resistance to aggressive media permits it to be used in laboratories and a large variety of industrial applications. The material resists most strong acids and bases even at relatively high temperatures and concentrations.Common trade names are: Densitec®, Hostalen®, Marlex®, Protec®, Propylux®, Polystone® and more.
