Processing
- This resin can be processed on all types of injection moulding machines.
- The high melt flow index of Lotrene MG70 leads to excellent flowability and processability.
- The items produced from this grade possess high flexibility and glossy surface.
- The temperatures and pressures used for the processing of LDPE MG70 are normal for the injection of low- density polyethylene of high melt flow index.
- The melt temperature range suggested is between 150 °C and 170 °C. However, optimum conditions are dependant on the equipment used (presses, moulds, etc.) and the articles under production (appearance, size, shape, etc.)
