DUPONT DELRIN 127UV POM Resin

Physical Properties

• Density: Measured according to the ISO 1183 standard, the 1.42 g/cc (0.0513 lb/in³) density is a basic parameter for material selection in various applications.
• Water Absorption: Absorbing 0.50 % in 86400 seconds and 1.2 % at 2.00 mm thickness (Sim. to ISO 62), it affects product performance in humid environments.
• Moisture Absorption: At 2.00 mm thickness, the 0.300 % moisture absorption influences the electrical and mechanical properties of the material.
• Linear Mold Shrinkage: Measured by ISO 294 – 4 and 2577, it is 0.021 cm/cm in the flow direction and 0.019 cm/cm transversely, important for mold design accuracy.
• Melt Flow: Measured by ISO 1133 at 190 °C under a 2.16 kg load,  the melt flow rates are 1.9 g/10 min (in cm3/10 min) and 2.4 g/10 min.

Polymer Properties:

1. Base Material: Polyoxymethylene (POM)
2. Key Features & Characteristics:
   • Formulated with UV inhibitors to prevent brittleness and color fading.
   • Rigid structure withstands mechanical stress, maintains shape for durable parts.
   • Medium-viscosity grade balances processability for injection molding and extrusion.
   • Natural low COF and high wear resistance suit moving components.
   • Low moisture absorption ensures precise dimensions in varying environments.

Applications:

The combination of UV resistance, high strength, and dimensional stability makes Delrin 127UV 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.
