Abstract
Several actual polyolefin based materials are formulated to exhibit high fluidity
to fill larger and thinner mold cavities for stringent automotive requirements.
Talc is generally used in such products as active an modifier, for instance, to
enhance stiffness, to lower molding shrinkage and to minimize CLTE. Very fine,
to ultrafine talc grades are normally formulated to achieve superior reinforcing
results, preserving the resistance to impact, typically requested for many
automotive formulations.
To get the best results in polymer modification, it is fundamental to achieve
the maximum talc dispersion in the polymeric matrix. The usage of high fluidity
resins could lead to some possible talc dispersion problems with subsequent
lack in mechanical and aesthetical properties.
IMIFabi Talc company has recently developed a new portfolio of products
specifically designed to maximize talc dispersability, granting higher
mechanical performances in the final compound even in high melt flow TPOs.
IMIFabi will present their latest results in modifying high fluidity TPOs with this
innovative family of products.
