Celanese Hostaform C 27021 POM Description
Hostaform C27021 is a high-flow copolymer of formaldehyde produced by Celanese Corporation, also known as “POM-C material.” With a melt flow index of 24, it offers a high level of flow and is particularly suitable for the production of parts with long runners, complex and precision components, and thin-walled products.
Celanese Hostaform C 27021 POM Advantage
- High liquidity POM, Compared to the more commonly used C9021 POM, the most significant difference in Hostaform C27021 POM resin lies in its melt flow rate, which reaches 24 cm³/10 min—far exceeding the 9 cm³/10 min of C9021 POM. This higher flow rate makes it particularly suitable for producing products with long runners, as well as precision, complex, and ultra-thin-walled parts.
- Automotive applications, Hostaform C 27021 POM resin has received multiple certifications, including BMW GS93-16, Bosch N28 BN 22-O028, Continental TST N 055 54.12, Ford WSK-M4D635-A3, and Nissan POM-IHx-1. It can be used with confidence in automotive applications and does not require additional certification.
