描述
Hostaform C 13021 ECO-C 872 POM is a sustainable polyoxymethylene copolymer resin developed by Celanese for precision injection molding applications requiring high stiffness, excellent toughness, dimensional accuracy and long-term durability. This grade belongs to the Hostaform ECO-C product family and uses circular carbon content derived from captured carbon dioxide emissions through an ISCC CFC certified mass-balance process. It provides a lower-carbon alternative while maintaining the same performance and processing properties as conventional Hostaform C 13021.
Hostaform C 13021 ECO-C 872 retains the outstanding characteristics of POM copolymer materials, including high rigidity, hardness, low moisture absorption, excellent dimensional stability and resistance to chemicals, solvents, fuels and strong alkalis. The copolymer structure also provides excellent resistance to hydrolysis, thermal degradation and oxidative aging, allowing components to maintain reliable performance during long-term service.
Compared with many engineering plastics, POM provides excellent sliding properties, low friction characteristics and good wear resistance. Hostaform C 13021 ECO-C 872 is suitable for precision components requiring smooth operation, low noise and stable dimensional performance. These properties make it widely used in automotive systems, mechanical transmission components and electrical applications.
The material offers a balanced combination of stiffness and toughness. With a tensile modulus of approximately 2900 MPa and tensile strength of approximately 65 MPa, Hostaform C 13021 ECO-C 872 provides reliable mechanical performance for precision molded components.
Hostaform C 13021 ECO-C 872 features excellent injection molding performance with good flow characteristics. The melt volume flow rate is approximately 12 cm³/10 min (190°C/2.16 kg), allowing efficient processing of thin-wall components and complex geometries while maintaining consistent production quality.
Typical applications include automotive components, precision gears, bearings, mechanical parts, electrical components and household appliances. With the same performance level as conventional Hostaform materials and improved sustainability characteristics, Hostaform C 13021 ECO-C 872 provides an environmentally improved solution for high-performance engineering plastic applications.
