High-density polyethylene (HDPE) is a thermoplastic polymer produced from ethylene. Properties:
• Good chemical and moisture resistance
• Poor wear resistance
• Low sliding resistance
• High workability
• Excellent surface finish
• Good dimensional stability
HDPE reinforced with glass fibres. Properties:
• Good chemical and moisture resistance
• Good wear resistance
• Low sliding resistance
• Good dimensional stability
• Excellent surface finish
• Best quality/price ratio
HDPE with ceramic reinforcement. Properties:
• Good chemical and moisture resistance
• Best wear resistance
• Sliding resistance almost absent
• High workability
• Good thermal deformation resistance
• Good dimensional stability
Self-lubricating HDPE / Graphite composite. Properties:
• High concentration of graphite endures emergency situations such as dry running.
• L version (low graphite content) can be used for speeds up to 800m/min.
• H version (High graphite content) is excellent for speed exceeding 800m/min.
• Low sliding resistance and consistent energy savings.
• Increased life of cylinder shells.
• The H version guarantees a double life-time compared to the L version.
