Plastic Material Options
Engineering Plastics for Custom Gears
Explore POM, PA66, PEEK and PPS materials for custom plastic gears. Each offers different mechanical, wear and thermal properties to suit specific operating conditions and transmission requirements.
POM (Acetal)
Low Friction & Wear Resistance:POM offers good sliding properties and wear resistance, making it a common choice for precision plastic gears.
Dimensional Stability:Its low moisture absorption helps maintain gear dimensions and consistent meshing in compact transmission systems.
PA66 (Nylon)
Strength & Toughness:PA66 provides good mechanical strength, impact resistance and wear performance for a range of plastic gear applications.
Load-Bearing Performance:Suitable for mechanical drives and actuators, with moisture absorption and operating temperature considered during gear design.
PEEK (Polyether Ether Ketone)
High-Temperature Resistance:PEEK retains useful mechanical properties at elevated temperatures, making it suitable for demanding transmission applications.
Chemical & Wear Resistance:Offers excellent resistance to many chemicals, with wear performance depending on the material grade, load and mating surfaces.
PPS (Polyphenylene Sulfide)
Thermal & Chemical Stability:PPS provides good heat resistance and resistance to many chemicals, making it suitable for specialized industrial environments.
Dimensional Stability:Low moisture absorption supports dimensional consistency, while gear toughness and wear resistance depend on the selected grade.
