Polypropylene (PP)

Polypropylene  is the lowest rated common fiber as far as temperature is concerned, but it exhibits one of the best chemical, properties which match well with many specialist industries.

Under dry, non-aggressive conditions it will operate continuously at 90 ° C. It is a very low density fiber (it floats in water) and as a consequence it tends to produce; around 30% thicker than polyester.

Due to their chemical structure, the fibers do not hydrolyze, their weakness is a susceptibility to oxidation, so care is needed if strong oxidizing agents.

Polypropylene fiber is prone to accumulation of static, so it is often added to conductive fibers or a conductive grid, or a combination of both. This helps to dissipate potential static discharges.

Application in the following industries:

  • electroplating plants / galvanisation
  • steel production
  • fertilizers production
  • foods
  • detergents
  • liquid filtration
Chemical resistance:

  • Acids – excellent
  • Alkalis – excellent
  • Oxidizers -not bad
  • Hydrolysis – excellent
  • Solvents – good

Maximum Continuous in Dry Conditions:  100°C 
Maximum Surge in Dry Conditions:  110°C
