Thermoplastics

Polypropylene is a good choice for  many fabricated parts

Polypropylene

  • Economical
  • Lightweight
  • Good thermal insulation properties
  • Excellent chemical and fatigue resistance
  • Easily welded and machined
  • Superior dielectric strength

Characteristics

Cost-effective and lightweight, polypropylene is easily welded, formed and machined. With its balance of chemical, thermal and electrical properties and good strength-to-weight ratio, it's a suitable choice for many applications.

Polypropylene has excellent chemical and solvent resistance and very low gas and water vapor permeability. As a result, Polypropylene is a cost-effective plastic materialit is used extensively in the semiconductor industry. It is also a good choice for the food processing industry. With a hard, high-gloss surface, it is suitable for environments in which bacteria is a concern including applications involving direct food contact.  Its good insulating properties, excellent arc resistance and dielectric strength also make it a good choice for electrical applications. It can be modified to be conducive or antistatic.
