Polypropylene (PP)

Polypropylene (PP)

Description

Polypropylene is a semi crystalline thermoplastic with high rigidity and very good chemical resistance. A distinction is also made between homopolymers and copolymers, copolymers are tougher but have less mechanical and chemical stability. The stock shapes offered by us are PP homopolymers as they are a superior type of PP.

Application

  • Pump parts
  • Component parts in chemical apparatus construction
  • Fittings
  • Valve bodies
  • Product holders for electroplating processes
  • Punching pads

PP-H is subject to strong sliding abrasion and is thus not suitable for use in sliding applications.
PP-H is resistant to acids, alkaline solutions, salts and salt solutions, alcohols, oils, fats, waxes and many solvents. Aromatics and halogenated hydrocarbons cause swelling. PP-H is not resistant to strong oxidizing materials (e.g. nitric acid, chromic acid or halogens) and there is a danger of stress corrosion cracking.
PP-C with high impact strength and superior strength and its lower susceptibility to tension cracks are widely used for chemical, mechanical and electronic industry, e.g. tanks, lab equipments, etching equipments, semiconductor processing equipments, plating barrels, machined parts in industrial doors, swimming pools and so on.
PP-S with excellent low flammability property are used for special areas, such as in ventilation systems and electrical engineering.
PP-FG reinforced with fiber glass has higher strength than common PP sheets and are ideal for structural tanks and linings, Ducts and fume hoods, plating barrels and so on.

Main Properties

The main benefits of PP are:-

  1. Low density compared to other materials.
  2. Minimum water absorption.
  3. Excellent chemical resistance even solvents.
  4. High corrosion resistance.
  5. Very good electrical insulator.
  6. Physiologically safe.
