CELANESE CELCON M90UV POM Resin

Physical Properties

• Specific Gravity: Tested by ASTM D792, the material’s specific gravity is 1.41 g/cc, showing its density relative to water.
• Density: Measured according to ISO 1183, the density is 1.41 g/cc (metric) and 0.0509 lb/in³ (English), defining mass per unit volume.
• Moisture Absorption: Under 23°C and 50%RH per ISO 62, it absorbs 0.200 % moisture, indicating water uptake tendency.
• Water Absorption at Saturation: Based on ISO 62, it reaches 0.75 % saturation, crucial for applications exposed to wet conditions.
• Linear Mold Shrinkage, Flow: Per ASTM D955, the flow – direction shrinkage is 0.022 cm/cm (0.022 in/in), important for mold design.
• Linear Mold Shrinkage, Transverse: As per ASTM D955, the transverse shrinkage is 0.018 cm/cm (0.018 in/in), ensuring dimensional accuracy of molded parts.
• Melt Flow: At 2.16 kg load and 190 °C per ISO 1133, the melt flow rate is 8.0 g/10 min, determining its fluidity during injection molding.

Polymer Properties:

1. Base Material: Acetal Copolymer (Polyoxymethylene – POM)
2. Key Features
   
   • Natural UV – stabilized formulation for long – term outdoor use.
   • Standard flow grade suitable for a wide range of injection molding processes.

Applications:

The combination of UV resistance, high strength, and dimensional stability makes Celcon M90UV a leading material for a variety of outdoor and long-life applications.

• Automotive Exterior Parts: Ideal for components like door handles, trim clips, and fuel caps that are exposed to sunlight and outdoor elements.
• Outdoor Consumer Goods: Suitable for parts in garden furniture, playground equipment, and sporting goods where UV stability is critical.
• Industrial Components: Used for exposed parts in machinery, gear wheels, and control handles that require durability and resistance to environmental factors.
• Electrical and Electronic Parts: Employed in outdoor electrical connectors and housings where long-term performance and UV protection are essential.

Processing Guidelines

Celcon M90UV is optimized for injection molding and extrusion. Proper drying is crucial to ensure optimal processing and part quality.

• Drying: Although POM has very low moisture absorption, it is recommended to dry the material at 80°C for 3 hours to remove any surface moisture.
• Melt Temperature: 190-210°C
• Mold Temperature: 60-90°C
