DUPONT DELRIN 900P POM Resin

Physical Properties

• Density: Measured following the ISO 1183 standard, the 1.42 g/cc (0.0513 lb/in³) density is fundamental for calculating material volume – mass relationships.
• Water Absorption: Absorbing 1.4 % at 2.00 mm thickness (Sim. to ISO 62), it may lead to dimensional instability in products during use.
• Moisture Absorption: At 2.00 mm thickness, the 0.400 % moisture absorption affects the electrical and mechanical properties of the material.
• Linear Mold Shrinkage: With values of 0.019 cm/cm in both the flow and transverse directions according to ISO 294 – 4 and 2577, it is important for accurate mold design.
• Melt Flow: Measured by ISO 1133 at 190 °C under a 2.16 kg load, the melt flow rates are 21 g/10 min (in cm³/10 min) and 25 g/10 min  indicates high flowability during molding.

Polymer Properties:

1. Base Material: Polyoxymethylene (POM)
2. Key Features & Characteristics:
   • “P” (Plastified) grade reduces formaldehyde off-gassing, enhancing workplace safety and minimizing ventilation needs.
   • Ultra-low viscosity enables easy molding of complex multi-cavity parts, boosting production efficiency via faster cycle times.
   • Maintains high tensile/flexural strength despite high flow, ensuring rigid, durable components.
   • Natural low COF and wear resistance (like Delrin®) suit self-lubricating moving parts.
   • Low moisture absorption preserves precise dimensions across varying environments.
