With the increasing demand for high-temperature tape, Polyimide tape manufacturers 'quantities have become more. Production factory increases leading to a quality big problem in the market. Polyimide tape also has false, so many of my friends do not know how to identify it. We summarized several ways to distinguish Polyimide tape.
Method One: look at Material
Polyimidetape is mainly composed of the two most base and glue compositions. If it isfalse Polyimide tape, regardless of heat resistance or insulation properties ismuch lower than the real Polyimide tape.
Method Two: smell it
IfPolyimide tape is very strong and is accompanied by a surge of sour taste, thenthis Polyimide tape will much more likely be false, but also it's very pooradhesion and retention.
Method three: high-temperature test
Polyimideof the high-temperature test tape, after the high temperature, the peel forcecheck, whether there is residual glue, shrinkage phenomena. Because the heatresistance temperature tape Polyimide is usually between 120 to 260 degrees.
Methodf our: look at the appearance
Seesurface brightness Polyimide tape, in general, high-temperature tape color darklittle inferior, and the probability is very high fracture intensitydifference. Conversely, Polyimide tape good quality, the surface gloss is good.
Method five: see residue after combustion
You canstart with a lighter roast for 1-2 seconds, and then touch it. If it isunqualified, after burning touch, the adhesive will stick to the hands, if itis true Polyimide tape, the adhesive would be not glued to the hand.
Method Six: Material for detecting
WhenPolyimide tape is described, looking atthe Polyimide tape process. Because of different types, some Polyimide in thesame very high-temperature viscosity, high temperature after some torn withoutleaving adhesive residue, while others are not high-temperature deformation.
