POM-H GF20 is a 20% glass-fiber-reinforced acetal homopolymer engineered to deliver significantly higher stiffness, strength, and dimensional control than unfilled POM-H (Acetal Homopolymer). The 20% short glass-fiber loading increases the material's resistance to deflection under load and reduces its coefficient of thermal expansion, making it well suited for structural components that must maintain tight tolerances in thermally dynamic environments. Ready Plastics stocks POM-H GF20 sheet for industrial, automotive, and load-bearing precision applications.
The glass-fiber reinforcement in POM-H GF20 provides significantly increased rigidity compared to unfilled acetal grades, reducing creep and deflection under sustained load. This structural advantage makes POM-H GF20 a strong candidate for load-bearing housings, structural frames, brackets, and precision components in automation systems where dimensional stability under mechanical stress is critical. Reduced thermal expansion further supports tight fits and alignments in assemblies subject to temperature variation.
Trade-offs vs unfilled POM-H. While glass-fiber reinforcement improves stiffness and dimensional stability, the filler reduces ductility and lowers impact resistance compared to the unfilled POM-H base. POM-H GF20 also machines differently — cutting tools experience more wear from the glass fibers, and surface finish is typically rougher than unfilled acetal. For applications requiring a smooth surface or high impact resistance, unfilled POM-H or toughened grades are more appropriate. For specific mechanical and thermal properties, consult the datasheet.
Sister grades. For high-strength homopolymer acetal without reinforcement, see the unfilled POM-H grade page. For reduced friction in homopolymer acetal, see POM-H PTFE. For outdoor-exposed structural applications, POM-H UV adds UV stabilization to the homopolymer base.
