THREAD SEAL TAPE

PRODUCT DESCRIPTION:

Thread seal tapes from Unipak are white, non-adhesive thread seal tapes produced from pure Polytetraflourethylen PTFE.

APPLICATION:

PTFE-Tape with lower density <0,70g/cm3 are applied for the sealing of threaded joints on systems for water, compressed air, cooling and steam systems and hydraulic systems. Applicable on all types of materials (iron, metal, plastic, fibre etc.). Thread seal tape in general is also suitable on systems where heavy hygiene requirements are made (hospitals, food industry etc.) and all thread seal tape from Unipak can thus be used for drinking water and domestic water
Multitape and Topseal is used for sealing of threaded joints on installations with especially gas and oxygen, while Sealrite may be used on all types of installations with gas and lager threads.
The high density taps described here are applied for the sealing of threaded joints on systems for water, compressed air, cooling and steam systems and hydraulic systems. Applicable on all types of materials (iron, metal, plastic, fibre etc.) Topseal/Multitape/Sealrite is suitable for about all tubing materials like iron, stainless steel, cast metals, plastics, fibre etc. Sealrite is because of its thickness not so suitable for smaller threads.

TECNICAL PROPERTIES:

The exceptional strength and high molecular weight of the Polytetraflourethylen provides PTFE-tape series of outstanding qualities. PTFE in general has a temperature resistance from -200C to +260C. PTFE is resistant to almost all types of acids, bases, solvents, chemicals etc., however, with the exception of fluorine, some fluoride chemicals and melted alkali metals. PTFE also has a very low coefficient of friction. It is Non-inflammable (ASTM D-635 and D-470) and Non-ageing and has a High tensile strength even at low temperatures. Finally PTFE is breaking-down resistant, especially, in connection with bending and vibrations. All these properties make PTFE ideal for use in connection with thread sealing. Unipak offers a series of thread seal tapes with a different content or density of PTFE, ranging from the standard quality Unitape with a PTFE density of 0,35g/cm3 up to the high end quality Topseal with a content of 1,3g/cm3. The choice of tape type is determined by the job the tape has to solve. Price and specifications differs with the PTFE density. Please see below for further explanations.
