Celanese Hostaform C 13031 POM pellets Description

Hostaform C 13031 is a copolymer of formaldehyde (POM-C) produced by Celanese Corporation. It offers higher strength, stiffness, and hardness, while also being suitable for contact with food and drinking water. It has met the relevant certification requirements for POM materials set by major automakers and is suitable for the manufacture of automotive components, particularly those in contact with automotive fuels.

iAs shown in the image on the left, Hostaform C 13031 POM Natural is a milky white granule. Hostaform C 13031 POM Black is also available. If you require POM material in other custom colors, please contact us.

Celanese Hostaform C 13031 POM pellets Advantage

Higher strength. Compared to conventional formaldehyde-copolymer materials, C 13031 POM has a tensile modulus of 3050 MPa and a tensile stress at yield of 68 MPa. With its higher mechanical strength, it is suitable for the production of high-load components such as high-rigidity structural parts, gears, and precision machined parts.

Table 1. Key Performance Differences Between Hostaform C 13031 and Hostaform C 9021 POM

Automotive applications POM, As a POM material specifically designed for automotive applications, Hostaform C 13031 has met the material certification requirements of numerous automakers, including Bosch, Chrysler, Continental, Ford, GM, Daimler, PSA, Renault, and VW/Audi, and can be used with confidence in automotive applications, due to its excellent fuel resistance, it is particularly suitable for automotive fuel-contact applications.
Better liquidity, Compared to the commonly used Hostaform C 9021 POM, which has a melt volume rate (MVR) of 9 cm³/10 min at 190°C and 2.16 kg, Hostaform C 13031 achieves an MVR of 12 cm³/10 min. Its higher flow rate makes it suitable for the production of precision, complex, and thin-walled mechanical parts.
