LITEPOL® is a new family of extra light engineering plastics based on Polypropylene or Polyamide and filled with Hollow Glass Microspheres.
LITEPOL® compounds are suitable for all those applications in which weight reduction is the primary objective: for this reason they are particularly aimed at the automotive industry which is subject to strict regulations and targets in terms of reducing emissions.
DENSITY AND STIFFNESS
The following charts show the density /tensile modulus ratio of different mineral fillers at different percentage (variations vs unfilled grades).
LITEPOL® filled with Hollow Glass Microspheres only, provides a weight reduction ranging from 9% to 30% and improvement of stiffness (tensile modulus) from 13% to 79% depending on the polymer base and on the percentage of microspheres used in the compound.
LITEPOL® mixed grades HB+10%GF provide an excellent density/stiffness ratio: weight reduction ranges from 3% to 19% with improvement of the tensile modulus values from 60% to 179%.
For applications requiring both lightweight and impact resistance, LITEPOL® mixed grades filled with Hollow Microspheres and chemically bonded Glass Fiber are the most suitable, as they provide a weight reduction ranging from 3% to 19% and improved impact values from +20% to +218%, depending on the base polymer and on the percentage of filler used in the compound.
MIXED HB/GF GRADES VS TALC FILLED GRADES
Mixed HB/GF LITEPOL® grades show excellent low density and mechanical performance compared to talc filled grades.
