High modulus Polypropylene CNF Pellets

Polypropylene pellets containing Carbon Nano Fibers for reinforcement

The pellets are made by adding 10%, 20%, or 30% of ALMEDIO‘s Carbon Nano Fiber (CNF) to polypropylene (PP) as reinforcement. The addition of 30% of CNF provides a flexural modulus of 9.2 GPa, about 8 times higher than that of the product with no reinforcement. By blending with the CNF as a high concentration such as 30%, not only flexural modulus but also flexural stress is about doubled, the thermal conductivity is 5 times, and the volume resistivity can be greatly changed from an insulator to a conductor. The fiber length of the CNF used is as short as 15um or less, so the surface of the molded product is smooth and recyclable and even if the product is re-molded, the fibers will not break and the properties will not be lost. It is an eco-friendly product that allows the resin to be used without waste.
