Processing Guidelines

LDPE Lotrene MG70 can be processed on all standard types of injection molding machines. Its high melt flow index provides excellent melt flow behavior, resulting in easy mold filling and efficient processability.
Products manufactured from MG70 exhibit high flexibility and an attractive glossy surface finish, making the grade suitable for applications where both performance and appearance are important.
The processing temperatures and pressures required for MG70 are typical of high melt flow LDPE injection molding grades. A recommended melt temperature range of 150 °C to 170 °C is suggested. However, optimum processing conditions may vary depending on the specific equipment used (such as injection machines and molds) and the characteristics of the final articles, including appearance, size, and geometry.
