Benefits

  • Relatively high fatigue strength.
  • Stiffer than PEHD.
  • Retains its mechanical properties better at high temperatures than PEHD.
  • Excellent dielectric properties.
  • Low density (floating).
  • Chemical resistance similar to polyethylene, but not the same tendency to stress cracking due to. surrounding medium.
  • Reinforced grades have a stiffness similar to unfilled nylon but at a lower price.
  • Mechanical and electrical properties are also maintained in water.
  • Non-toxic grades can be steam sterilized.

Restrictions

  • Becomes brittle below -20 ° C.
  • Degraded by UV radiation if it is not stabilized.
  • Attacked by oxidizing acids.
  • Thermal stability is reduced upon contact with copper.
  • Easier to glue together with other materials, such as wood and aluminum than with yourself.

Specific properties

Polypropylene homopolymers, referred to as PP-H, are thermoplastic resins produced through the polymerization of propylene with Ziegler-Natta catalysts. The PP-H has great durability, and material stiffness and can be used in different processing technologies, such as:

  • injection molding
  • blow molding
  • film
  • fiber
  • sheet extrusion
  • thermoforming

PP-Homopolymer has excellent resistance in contact with acids, bases, and solvents. The material has a lower density than PE. PP is well suited for applications in microwave environments.

The material is USP Class VI approved and is used in medical technology applications and is delivered from at least two material suppliers.
