Overview
HDPE (High-Density Polyethylene), also known as PE300, is a robust, lightweight and economical engineering plastic used in a wide range of general-purpose applications. It is valued for its excellent impact strength, resistance to many chemicals and non-toxic properties, making it particularly suitable for food contact and hygienic environments. HDPE has good sliding properties and absorbs virtually no moisture, ensuring consistent performance in wet and damp conditions. Its machinability and weldability also make it easy to fabricate into custom parts for industrial use.
