These settings yield a sample moulding shrinkage of 1,31% near to the sprue and 1,41% far from the sprue; in direction of the melt flow an average moulding shrinkage of 1,54% and 1,52% respectively were measured. Increasing the holding pressure reduced material shrinkage somewhat.

ADDITIONAL REASONS TO USE LUCOFIN® IN INJECTION MOULDING

• Lucofin® 1400MN to be added to e.g. PP pallets in order to increase PP’s CoF (coefficient of friction) value preventing boxes to slip away from the pallets
• Lucofin® 1400HN reduces viscosity of PP-recycled materials
• Lucofin® 1400MN can be used as impact modifier on an injection moulding machine for e.g. PA6 without a pre-compounding
• Lucofin® 1400MN and Lucofin® 1400PN are used for blends with renewable raw materials without the necessity to use processing aids
• Lucofin® products yield a high quality, non-sticky, dry-haptic to injection moulding parts
• Lucofin® 1400PN exhibits a doubled MFR compared to Lucofin® 1400MN while mostly retaining structural viscosity important in applications for e.g. injection moulding with black/colored masterbatch.
