Rigid POM Polyoxymethylene Engineering Plastic Sheets
The core value of POM C Sheets lie in their comprehensive characteristics of "high rigidity, high wear resistance, chemical corrosion resistance, and easy processing". It is suitable for fields such as automotive manufacturing, precision machinery, electronic appliances, and food processing, and performs particularly well in scenarios requiring high precision, low friction, and durability.
Product Advantages
Balanced Rigidity and Wear Resistance
POM-C Sheet's ultra-high rigidity (elastic modulus 2800-3200 MPa) and high wear resistance (Akron abrasion value ≤ 0.05 cm³/1.61 km) make it a core material for automotive parts and precision machinery. For example, in synchronizer rings in automotive transmissions, POM-C sheet's high rigidity (resisting gear mesh deformation) and wear resistance (friction coefficient of 0.2-0.3) significantly reduce transmission noise (by 15-20dB) and extend service life (>100,000 kilometers). In spindle bearings for precision machine tools, its low coefficient of thermal expansion (50%-60% lower than aluminum) ensures machining accuracy (error <0.01mm), while its fatigue resistance (>10⁷ cycles) ensures long-term stable operation. In the gear transmission systems of automated equipment, POM-C sheet replaces metal gears (reducing weight by 50%-60%) while still being able to withstand high torque loads (transmission efficiency >95%).
Chemical Resistance and Dimensional Stability
POM C Sheet is stable to most acid, alkali, and salt solutions and organic solvents (no significant swelling at concentrations below 30%). Its low thermal expansion coefficient (8-10×10⁻⁵/°C) makes it an outstanding performer in chemical environments and precision electronics. For example, in chemical pump impellers and seals, POM-C sheet's chemical resistance (resistance to acid/alkaline solutions with a concentration of less than 30%) and hydrolysis resistance (no performance degradation in humid environments) ensure long-term leak-free operation (service life >8 years). In electronic chip packaging molds, its low thermal expansion coefficient (matching the thermal deformation characteristics of silicon chips) ensures chip packaging accuracy (error <5μm), while its chemical resistance (resistance to photoresist and etching solutions) extends mold life (>100,000 molding cycles). In precision measuring instrument components in laboratories, POM-C sheet's dimensional stability (deformation <0.05% under temperature fluctuations) and chemical resistance (resistance to cleaning agents) ensure accurate measurement data (error <0.1%).
Ease of Processing and High Production Efficiency
POM-C sheet's ease of processability (short injection molding cycle, tight extrusion thickness tolerance) and waste recyclability (recycling rate >90%) significantly reduce production costs. For example, in the injection molding production of automotive interior parts, the molding cycle of POM-C sheets is 10%-20% shorter than that of POM-H (reducing the unit cost by 15%-25%). At the same time, its high fluidity (melt flow rate MFR 10-20g/10min) supports complex structural designs (such as gear assemblies with inserts). In the extrusion process of electronic and electrical housings, the sheet thickness tolerance of ±0.15mm (more precise than POM-H) reduces the amount of subsequent processing (saving 30%-40% in labor costs). In the large-scale production of civilian plastic products (such as plastic gears and zippers), POM-C sheet waste is 100% recyclable (crushed and directly used for injection molding), and the overall cost is lower than that of metals (such as zinc alloy and aluminum alloy).
