DUPONT DELRIN 511P POM Resin

Physical Properties

• Specific Gravity: Measured by the ASTM D792 standard, the specific gravity of 1.42 g/cc is useful for comparing the material’s density with others in material selection.
• Density: According to the ISO 1183 standard, the density is 1.42 g/cc (0.0513 lb/in³), consistent with the specific gravity, which helps estimate material quantity.
• Water Absorption: Absorbing 0.30 % at 23.0 °C after 24 – hour immersion and 0.90 % at saturation, it influences product performance in humid conditions.
• Moisture Absorption: At 23.0 °C and 50% RH equilibrium, the 0.20 % moisture absorption affects the long – term stability of the material.
• Linear Mold Shrinkage: Varying from 0.015 – 0.020 cm/cm depending on thickness and direction as per ASTM D955 and ISO 294 – 4, it is crucial for mold design to ensure product accuracy.
• Melt Flow: Measured by ASTM D1238 at 190 °C under a 1.05 kg load, it is 7.0 g/10 min, and by ISO 1133 at 190 °C under a 2.16 kg load, it is 15 g/10 min, showing melt fluidity.
• Melt Index of Compound: At 190 °C under 2.16 kg load, it’s 13 g/10 min (cm3/10 min, ISO 1133), indicating compound’s flow characteristics.

Polymer Properties:

1. Base Material: Polyoxymethylene (POM)
2. Key Features & Characteristics:
   • Formulated for enhanced impact resistance, outperforming standard POM grades in shock/drop tolerance.
   • “P” (Plastified) grade reduces formaldehyde off-gassing, improving workplace safety.
   • Low viscosity enables easy molding of complex/thin-walled parts, boosting production efficiency via faster cycles.
   • Maintains high tensile/flexural strength despite high flow, ensuring rigid, durable components.
   • Low moisture absorption preserves precise dimensions across varying environmental conditions.

Applications:

• Automotive Interior Components: Ideal for small, complex parts like gears in power windows, dashboard controls, and fuel caps that require high precision, durability, and impact resistance.
• Consumer Electronics: Suitable for parts in mobile device enclosures, laptop housings, and printer housings where high-precision, thin-walled components are needed and must withstand accidental drops.
• Precision Engineering: Used for tiny, intricate parts in toys, lock components, and precision gears where a clean fill, minimal cycle time, and toughness are essential.
• Electrical and Electronic Parts: Employed in small electrical connectors and switch housings where intricate geometry, durability, and impact resistance are required.
