BASF Ultraform W2320 003 PRO AT Medical POM Resin

Physical Properties

• Density: Measured in line with ISO 1183, the density is 1410 kg/m³. This quantifies the mass per unit volume of the material, a key parameter for applications considering weight and bulk.
• Shrinkage (Flow): As per ISO 294, the flow – direction shrinkage is 2.0 %. It’s vital for predicting dimensional changes during processing in the flow – aligned direction.
• Shrinkage (xFlow): Based on ISO 294, the cross – flow shrinkage is 2.1 %. This value is important for ensuring accurate part dimensions perpendicular to the flow path.
• Water Absorption: According to ISO 62, the water absorption is 0.8 %. It reflects the material’s susceptibility to moisture uptake, which can impact its performance over time.
• Melt Index (190°C, 2.16kg): Tested according to ISO 1133, at 190°C under a 2.16 kg load, the melt index is 25 cm³/10min. It indicates the material’s flowability when molten, guiding processing operations.
