DUPONT DELRIN 527UV POM Resin

Physical Properties

• Density: Determined by the ISO 1183 standard, the 1.42 g/cc (0.0513 lb/in³) density is useful for calculating material volume – mass relationships in product design.
• Water Absorption: Absorbing 0.50 % in 86400 seconds and 1.2 % at 2.00 mm thickness (Sim. to ISO 62), it may cause dimensional changes in products.
• Moisture Absorption: At 2.00 mm thickness, the 0.200 % moisture absorption affects the long – term performance of the material.
• Linear Mold Shrinkage: Measured by ISO 294 – 4 and 2577, it is 0.020 cm/cm in the flow direction and 0.019 cm/cm transversely, crucial for accurate mold design.
• Melt Flow: Measured by ISO 1133 at 190 °C under a 2.16 kg load, the melt flow rates are 13 g/10 min (in cm³/10 min) and 15 g/10 min.

Polymer Properties:

• Base Material: Polyoxymethylene (POM)
• Key Features
  
  • UV stabilization for strong resistance to ultraviolet radiation.
  • Maintains excellent mechanical qualities like high strength, impact resistance, and stiffness after long – term UV exposure.
  • Higher thermal stability compared to some other POM grades.

Applications:

• Automotive: Used for exterior mirror housings and trim, protecting against UV – caused fading and cracking in various weather conditions.
• Outdoor Equipment: Ideal for garden tool handles and lawnmower components, ensuring long – lasting use under sunlight exposure.
• Marine: Employed in boat deck fittings and railings, resisting UV and saltwater damage for reliable performance.
• Solar Energy: Applied to solar panel mounting brackets, maintaining dimensional stability in continuous sunlight.
