The insulating tape ANB 843 is made with twisted parallel glass fibres impregnated with a special polyester resins stabilized at an intermediate stage (stage B) that gives to the tape a certain adhesive grade in order to effect the tapping without slipping and to unroll the coil without difficulty. Subsequently this resin is completely polimerized according to a definite thermic cycle. The tape has high tensile strength whether in application phase or after the oven polymerization and a very good insulation property and flattering currents resistance.

The tape ATR 851 is a plastic film with polyester, flexible and strong. It is manufactured with a process that have a post orientation with uniform unidirectional retiring when it is submitted to heat. This property enable, in some cases, to have the easier and cheaper way to apply a certain pressure on different objects and structures. The tape retiring begins at 80°C but it reaches its top value between 110°C and 140°C. As there is not a critical temperature it is possible to have results also with heating between 130°C and 200°C; besides this temperature the characteristics degrade.
