Aramid paper adhesive tape

Aramid paper Silicone Adhesive Tape is a pressure- sensitive tape made of aramid paper coated by  silicone adhesive.  Due to excellent

heat-resistance, good adhesivity, flexibility, anti-tearing, anti-chemical corrosion and high mechanical strength, it is applicable to class-H  heat-resisting

insulation in electrical and electronic industry.

Note: Aramid paper is abbr. of polyaromatic amide fiber paper (NOMEX is commodity name of Duponts aramid paper)

Characters:

* Excellent heat resistance ,used as class-H insulation and can work for a long time ( 200℃);

* Good adhesivity, flexibility, applicable to appearance protection for all kinds of irregular materials;

* Stripping off after long time thermal-hardening, no residual glue;

* High mechanical strength, suitable for coils wrapping;
