描述
Hostaform C 13031 K POM is a high-performance polyoxymethylene copolymer resin designed for applications requiring higher mechanical strength, rigidity, hardness and wear resistance than standard POM materials. This grade uses special chalk modification technology to enhance mechanical performance while maintaining the excellent chemical resistance and processing characteristics of the Hostaform POM family.
Compared with Hostaform C 13021, Hostaform C 13031 K provides improved stiffness and hardness, making it suitable for components exposed to continuous mechanical stress, friction and repeated movement. The material maintains excellent dimensional stability and low moisture absorption, helping molded parts achieve precise tolerances during long-term operation.
Hostaform C 13031 K has excellent resistance to solvents, fuels, lubricants and strong alkalis. The POM copolymer structure also provides good hydrolysis resistance and high resistance to thermal and oxidative degradation, allowing components to maintain stable performance in demanding environments.
The low-friction and wear-resistant characteristics of this grade make it particularly suitable for mechanical moving components. It is commonly used in unlubricated or lightly lubricated sliding applications, gears, bearings and transmission components where smooth operation and long service life are required.
Hostaform C 13031 K provides good injection molding performance with an MVR of approximately 11 cm³/10 min (190°C/2.16 kg). The material can be processed using standard injection molding equipment and is suitable for precision components with complex geometries.
Typical applications include automotive mechanisms, precision gears, sliding components, mechanical assemblies and industrial parts. Its combination of high rigidity, wear resistance and dimensional stability makes Hostaform C 13031 K a reliable engineering plastic solution for demanding applications.
