Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Melting point/softeninig point of FMMVF fibres varies within the range of ca. 680 °C to ca. 720 °C depending on the fibre type.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 700 °C
Additional information
Melting point ( softening point) of MMVF fibres varies within the range of ca. 650 °C to ca. 1200 °C depending on the fibre type. Internal assessment based on measured data received from the manufacturers' over an 18 month period was used for QC analysis, comparable to a guideline study. Typically B and C Glass would be completely molten glass at temperatures around 800°C and will have lost all fibre form. B and C Glass microfibres have a softening point of around 680 °C, whereas A Glass microfibres have asoftening point of 720°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
