POLYPROPYLENE
FIBRE
The Steel of Plastics
Polypropylene is known as the ‘steel of plastics’. It has characteristics and properties that can be altered to suit a wide range of applications, making it extremely versatile. As one of the most popular plastics in the world for its resistance to fatigue, low melting point, recyclability, low-moisture absorption, high flexural strength, durability in high stress environments, and affordability, polypropylene is in very high demand.
Polypropylene fibres are suitable for several applications. They are predominantly used in the automotive industry, packaging, fashion, sports, and medicine.
Quality matters, so at Goonvean Fibres, we’ve added further value to our polypropylene fibres, including zero fusion, unrivalled flow characteristics, shorter cut lengths, and lower overall customer production costs.
Available in a range of sizes
Standard Fibre Details
Polypropylene fibres are suitable for a variety of industries. It’s a quality reinforcement fibre that can withstand high-stress environments and where there is a large volume of foot traffic. They can be found in most products we use and know, such as floor furnishings, kettles, food containers, packaging, vehicle components, medical mesh, and nappies.
Our Short-Cut Polypropylene fibres are also used as an additive to concrete for the construction industry to prevent cracking and spalling.
Technical Fibre Details
Polypropylene is also known as the PP fibre, and it’s the first stereoregular polymer that’s become a significant component for manufacturing in the industrial industry. PP is a thermoplastic, which means it has a linear structure based on the monomer CnH2n and is originally manufactured from propylene gas.
To create the fibres out of polypropylene chips, manufacturers carry out traditional melt spinning, using heat to melt the polymer to a viscosity that’s suitable for plastic extrusion.
