Production
Polymerisation is used to form the polymer. The polypropylene fibres are spun using a melt spinning process.
Properties
- Similar to polyethylene (PE)
- Low density
- High resistance to alkalis and acids; soluble in chlorinated hydrocarbons at 70°C (toluene, xylene)
- Good resistance to decay
- High electrical insulation capacity
Temperatures
- Melting point: approx. 160°C to 175°C depending on type
FAQ
-
Polypropylene fibres are produced by polymerisation. The polymer is processed into filaments using the melt spinning process.
-
Polypropylene offers low density, good chemical resistance, resistance to decay and high electrical insulation capacity.
-
Polypropylene has similar properties to polyethylene, particularly in terms of low density and chemical resistance, but differs in specific chemical behaviour and performance characteristics.
-
Yes. Polypropylene has high resistance to alkalis and acids. However, it is soluble in chlorinated hydrocarbons such as toluene and xylene at approximately 70°C.
-
Polypropylene has very low moisture absorption, contributing to dimensional stability in humid environments.
-
Yes. Polypropylene provides good resistance to decay, supporting durability in outdoor or damp conditions.
-
Its low weight, chemical resistance and electrical insulation properties make it suitable for specialised technical uses.
-
Polypropylene has a melting point of approximately 160°C to 175°C, depending on the type.
-
Yes. Polypropylene is thermoplastic and softens or melts when exposed to high temperatures.
-
Polypropylene threads are used in technical textiles, filtration applications, packaging, geotextiles and specialised industrial products.
