Common Materials for Injection-Molded Pipe Fittings
The materials commonly used for injection-molded pipe fittings are listed below, with the selection depending on application scenarios, performance requirements, and cost considerations:
- ABS (Acrylonitrile Butadiene Styrene)
Properties: Good chemical resistance, surface hardness, machinability, and dyeability; high impact strength, stable low-temperature performance, and easy molding.
Applications: Widely used in cross pipe fittings, mechanical components, automotive parts, etc. - PE (Polyethylene)
Types: Includes HDPE (High-Density Polyethylene) and LDPE (Low-Density Polyethylene), as well as PE80 and PE100 (for high-pressure pipelines).
Properties: Corrosion-resistant, flexible, suitable for heat fusion and socket connections; commonly used in cold/hot water pipes and gas pipelines. - PP (Polypropylene)
Properties: Heat-resistant (up to 100°C+), chemically stable, but brittle at low temperatures.
Applications: Suitable for hot water fittings, food-grade containers, etc. - PVC (Polyvinyl Chloride)
Types: UPVC (Unplasticized PVC) and CPVC (Chlorinated PVC, heat-resistant).
Properties: Low cost, corrosion-resistant, but poor toughness; often used in drainage fittings and low-pressure pipe connections. - POM (Polyoxymethylene, Acetal)
Properties: High rigidity, wear-resistant, fatigue-resistant; suitable for precision pipe fittings, gears, and bearings.
Limitations: Vulnerable to strong acids and alkalis. - PEEK (Polyether Ether Ketone)
Properties: Heat-resistant (long-term use at 260°C), high strength, chemically inert; used in aerospace, medical, and high-end industrial piping.
Applications: Specialized pipe connections, such as high-temperature and high-pressure environments. - Other Specialty Materials
PA (Nylon): Wear-resistant, oil-resistant; used in hydraulic fittings.
PTFE (Polytetrafluoroethylene): Extremely corrosion- and heat-resistant but difficult to process; used in chemical industries.
Selection Criteria
Pressure Resistance: PE100 and PEEK are suitable for high-pressure environments.
Temperature Resistance: PEEK > PP > ABS > PE.
Cost Considerations: PVC and PE are the most economical, while PEEK and POM are more expensive.
