50% Glass Fiber Reinforced Polyketone — Exablend® POK GF50 S
Description
Exablend® POK GF50 S is a highly filled polyketone with 50% glass fiber for structural load-bearing parts. Tensile modulus of 17,000 MPa, tensile strength of 195 MPa, flexural strength of 220 MPa — the level of glass-filled PA66 GF50, but without its moisture dependency.
Flow-direction shrinkage of 0.1–0.3% is among the lowest in its class: the material holds tight tolerances and suits precision housings, brackets and warpage-critical parts. HDT of 205 °C at 1.8 MPa.
Minimal moisture uptake and the chemical resistance of the polyketone matrix make GF50 S an alternative to PA66 GF50 in assemblies exposed to fuel, oils and humidity. Processing: melt 235–255 °C, mold 60–90 °C (80 °C optimum), up to 25% regrind.
FAQ
When to choose POK GF50 over PA66 GF50?
When the part operates in humid or chemically aggressive environments: POK properties are humidity-independent, shrinkage is lower (0.1–0.3%), fuel resistance is higher.
How precise is the molding?
Shrinkage of 0.1–0.3% flow and 0.2–0.4% transverse — minimal anisotropy, stable tolerances, low warpage.
What is the heat resistance?
HDT of 205 °C at 1.8 MPa, melting point of 220 °C — continuous service at 100–140 °C with retained stiffness.
