High-performance polyolefin filaments
GRAUTS GmbH is a German company from the town of Löhne that presents a family of high-performance polyolefin filaments with a diameter of 1.75 mm. The range covers unfilled, mineral-filled and glass-fibre-filled materials, including a flame-retardant grade.

| HPP+15%GF+FR | 15 % glass fibre and flame retardant | class V0 at 1.6 and 3.2 mm | 2080 / V.1.001 |
| HPP+40%GF | 40 % glass fibre | modulus 6350 MPa; shrinkage 0 / 0.05 % | 1129 / V.1.001 |
Properties
More glass fibre — higher stiffness.
Reinforcement raises the modulus and heat resistance and lowers the elongation. Unfilled HPP 52ShD remains elastic — 520 % at break.
Application
Electrical engineering. Mechanical engineering.
Automotive industry.
Industries for which GRAUTS develops reinforced polyolefins: stiffness, heat resistance and stable geometry instead of PA+GF/CF.
