Adhesive tapes with metal foil
Electrically conductive metal tapes prevent interferences, vhich can be caused by other electrical componets and devices. Their applikation is necessery in the field EMV/ESD, where is required shielding, grounding and seduction electrostatic charge.

Every adhesive tape, generally every insulating material, is included in the certain temperature class. Temperature classes are referred to uppercase and indicate the highest temperature, which can be adhesive tape permanently stressed.

Rubber adhesive (130°C)
Rubber adhesives is due the additions of resins and substances for increase resistance to aging, good stickness and is resistant to impregnating varnishes and resins.
Acrylate adhesive (155°C)
The layer of acrylate adhesive, which is made from syntetic polymers,is generally thinner than rubber adhesive. Acrylate adhesive is resistant to light and aging. Resits well to impregnating resins including resins based on unsaturated polyesters. It is resistant to solvents and some oils.
Silicone adhesive (180°C)
Only silicone adhesive based on polysiloxans meets the requirements of insulating class H (permanently temperature 180°C). In a combination with nonflammable carriers (polyimid, glass fabric) is yielding an adhesive tape for applikations in extremelly conditions.
Thermosetting adhesives
By thermosetting adhesives occurs the elevated temperature to cure the adhesive layer. Thereby increasing its stickiness and especially resistance to impregnating resins .
Heat settings conditions
Rubber and acrylate adhesive:
1 hour by 150°C
2 hour by 130°C
3 hour by 120°C
silicone adhesive
2 hours by 260°C
24 hours by 260°C recommended for maximum protection against solvents

Certificate
Adhesive tapes are certified according to number UL (file number E20780, E315249) and according to CSA (file number LR96327):
(0) adhesive tape isn't certified according to UL
(1) adhesive tape is resistant to ignition according to UL510
Storage conditions
Adhesive tapes should be stored in their original containers, protected from light,by temperature between 15°C and 25°C, by relative humidity 50 ±30%. It is recommended by using of adhesive tape , which is stored by temperature lower than 15°C, to place the tape at 24 hours to room temperature, the tape gets back its characteristic properties.
Dimensional tolerances of tape widths
Adhesive tapes with foils: ±0,2 mm (±1/64“)
Adhesive tapes with fabrics: ±0,4 mm (±1/64“)
Adhesive tapes laminated: ±0,2 mm (±1/64“)
