Compression Molding

Compression molding is a fast running plastics conversion process for caps and closures providing an efficient processing in terms of short cycle times and low energy consumption. This results in superior performance in terms of throughput and dimensional consistency of final items. With a lower conversion temperature, material is less prone to degradation.

Grades from LyondellBasell typically used for injection molding are also used by customers in compression molding. ACP HDPE caps and closures grades with their pronounced shear thinning will provide in an over proportional lower flow resistance and therefore help maintain high throughput and superior characteristics on the final item, such as ESCR.
