Aramid paper acrylic Adhesive Tape is a pressure- sensitive tape made of aramid paper coated by acrylic adhesive, and slit after baked in special equipment. 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,etc.Note: .Aramid paper is abbr. of polyaromatic amide fiber paper (Nomex is commodity name of Dupont’s aramid paper)
Characters:
* Excellent heat resistance ,used as class-F insulation and can work for a long time (155℃);
* 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;
