Material
Acetal (Glass-Filled)
Acetal (Glass-Filled) is a reinforced engineering thermoplastic enhanced with glass fibers. This addition significantly increases the material's stiffness, creep resistance, and dimensional stability compared to standard acetal.
Manufacturing processes
About
Acetal (Glass-Filled) – typically containing 20% to 30% glass fibers – is engineered for applications that require high mechanical strength and rigidity. The glass reinforcement reduces the material's thermal expansion rate and significantly improves its performance under long-term mechanical stress (creep resistance).
While it retains the excellent chemical resistance and low moisture absorption of standard acetal, the fibers make it much stiffer and more resistant to impact-induced deformation. It is an ideal choice for high-load structural parts, industrial pump components, and automotive housings where maintaining precise tolerances under heat and pressure is vital.
