PTFE adhesive tape, also called Teflon adhesive tape, high temperature Teflon tape, self adhesive PTFE tape is made of PTFE coated fiberglass fabric treated with pressure sensitive silicone adhesive on one side.
Specifications of Teflon Adhesive Tape
Self adhesive PTFE tape has smooth surface, good anti-adhesion, chemical and high heat resistance and excellent insulation properties. The tape is widely used in packaging, thermoplastic, composite, heat sealing and electronic industries.
With glass fiber reinforced, PTFE adhesive tape offer high tensile strength, makes it perfect for sticking on the cylinder of sizing machine and demoulding of thermoplastic, the tape can be repeatedly used and easily replaced. Self adhesive PTFE tape is an alternative for PTFE spray, the tape can be easily attached on various flat and regular curved surface, eliminate the need of Teflon spray which require professional equipment and special production process.
Why PTFE Adhesive Tape Leave Residual Glue?
1. Unreasonable working temperature
Adhesive will peel off from the basic Teflon cloth during extremely high temperature, you can find some tiny residues by touching or close observation, the residues would have effect on your production, this phenomenon may occur because of higher working temperature, usual temperature resistance is 210-260℃.
2. Quality of High Temperature Teflon Tape
The adhesive coating process is very important, heating and curing process need to be proceed strictly according to the baking requirement of sensitive silicone adhesive, shorter curing time or faster coating speed would cause failure combination of glue, primer glue and basic fabric, then the glue would easily leave basic fabric.
3. The jumbo roll did not stand for a while before cutting
After coating process, PTFE adhesive tape will come out in big jumbo roll, but it is not done, the adhesive is not fully cured for now, stock the jumbo roll under natural conditions for 2-3days before slitting into small rolls, the glue will be completely cured and combined with basic fabric.
In order to avoid the residual adhesive, the first and most important thing is to control the quality of Teflon tape during production.
