What do lubricants do in the context of polymers?

Lubricants serve a crucial role in the processing and manipulation of polymers, particularly in the molding and extrusion stages. When added to polymers, lubricants reduce friction between the polymer and the machinery used during these processes. This reduction in friction facilitates smoother flow and movement of the polymer material, making it easier to mold into desired shapes. By decreasing the resistance encountered during processing, lubricants help in achieving a more uniform distribution of temperature and material consistency, ultimately resulting in higher-quality end products.

This benefit of ease in molding is particularly important in industrial applications where precision and efficiency are key, allowing manufacturers to produce components with complex geometries without experiencing issues like sticking to molds or uneven flow characteristics.
