WIC PP30 BK
What is it?
A grade of polypropylene compounded with 30% carbon fibre. The origin of the carbon fibres is the dry cut-offs from carbon fibre thermoset part production. The carbon fibres are industrial waste. Although the base material is PP, the carbon fibre reinforcement creates unique mechanical properties at low density. It is ideal for products or components that require high strength and stiffness but also benefit from low weight. WIC Carbon Fibre Products are also available with PA6, PA66 and PA66+6I/6T as the base polymer.

Technical benefits
The tensile strength and modulus outperform most heavily glass-filled engineering polymers. The density of the material is only slightly over 1 kg/dm3, which is an advantage, allowing the end product to remain at low weight. The material is electrically conductive. Compared with glass fibre-reinforced materials with equal mechanical properties, WIC compounds offer 20-30% weight-saving potential.
Look and feel
By comparing the sample with other samples, the stiffness/weight ratio is evident. Shiny surfaces appear matte because of the carbon reinforcement.
Environmental benefits
Recycled carbon fibre has low GWP (Global Warming Potential) compared with prime carbon fibre. Polypropylene as the base material has a low carbon footprint, and overall, this material shows a CO2-Footprint of 1,26 (kg CO2 eq) according to GaBi (DIN EN ISO14040/14044). Lightweight end product saves energy in transportation, especially in cars.
Applications
The material suits structural parts in automotive, household, sports, and leisure lightweight products. Some grades are also used for industrial applications in which material requirements are a combination of high strength and electrical properties (ESD).
Why we chose this material
Recycled carbon fibre, mechanical performance, low density... we see this as an exceptional material and are very happy to have it in the kit.
Why you should consider this material
-
