The results also show very clearly here that the addition of small amounts of Paxymer® reduces the addition levels of PFR, keeping V0 classification as it was theoretically expected. Our investigations into mechanical and processing properties revealed that such reductions in the additive levels had a significant positive effect on the final products, as the addition of higher levels of PFR are known to reduce both the impact resistance and the elongation of materials and negatively affect the rheological properties.
