It represents glass cloth treated by fluoroplast-4D pigmented suspension and heat-treated.
Varnished cloth is applied for production of big-volume protector caps and can be used under the working temperature range between -100°C and +250°C.
Depending on thickness varnished cloth is produced of following grades:
-
F-4D-Т-13-027-А
-
F-4D-Т-13-027-B
