描述
Hostaform C 13021 ECO-B POM is a sustainable polyoxymethylene copolymer resin developed by Celanese for precision injection molding applications requiring high stiffness, toughness, dimensional accuracy and long-term durability. This grade is part of the Hostaform ECO-B portfolio and delivers the same technical performance as conventional Hostaform C 13021 while supporting sustainability goals through a certified ISCC Plus mass-balance approach. Renewable feedstocks are used to reduce reliance on fossil-based raw materials and lower greenhouse gas emissions without changing the material’s processing behavior or end-use performance.
Hostaform C 13021 ECO-B maintains the excellent characteristics of POM copolymer materials, including high rigidity, hardness, toughness, low moisture absorption, excellent dimensional stability and outstanding resistance to chemicals, solvents, fuels and strong alkalis. The copolymer structure also provides improved resistance to thermal degradation, oxidative aging and hydrolysis compared with many conventional engineering plastics.
The material is designed for precision injection molded components and thin-wall parts requiring consistent dimensions and reliable mechanical performance. Its balanced combination of stiffness and toughness allows engineers to produce complex components with tight tolerances while maintaining durability during long-term operation.
Compared with standard POM homopolymer materials, Hostaform C 13021 ECO-B provides excellent processing stability and chemical resistance. The material offers good fatigue resistance, creep performance and wear behavior, making it suitable for moving mechanical components such as gears, bearings and sliding parts.
Hostaform C 13021 ECO-B is optimized for injection molding with a melt volume flow rate of approximately 12 cm³/10 min (190°C/2.16 kg). The good flow characteristics allow efficient processing of precision components and thin-wall designs while maintaining stable production quality.
Typical applications include automotive engineering parts, precision mechanical components, electrical and electronic components, household appliances and industrial components. With the same performance level as conventional Hostaform grades and improved sustainability characteristics, Hostaform C 13021 ECO-B provides a reliable solution for companies seeking high-performance engineering plastics with reduced environmental impact.
