Products Description
Engineered for ultra-thin electronics encapsulation, this double sided PET film mounting tape delivers structural bond strength within micro-gap component tolerances. The ultra-clear PET film tape serves as a dimensionally unyielding substrate that prevents lateral shear deformation in compact display frames, touch sensor stacks, and camera module bezels. As an advanced double coated polyester tape, it eliminates dielectric breakdown risks while maintaining planar uniformity during high-speed, automated kiss-cutting and vacuum-suction pick-and-place assembly.
Products Features
0.01mm Ultra-Thin Profile: Very thin gauge options (down to 0.01mm) fit tight gap spaces in smartphones and wearable display assemblies.
Clean Slitting & No Edge Ooze: Firm acrylic adhesive resists cold flow under pressure. Keeps roll edges non-sticky, prevents blade gumming, and stops matrix jamming during fast die-cutting.
Clear Optical View: High transparency prevents shadows, Newton's rings, or visual distortion when laminating display glass and lenses.
Vibration & Drop Resistance: Holds tight under constant shaking and drop impacts without shifting or loosening along the bond line.
Flat Roll Unwinding: Uniform tension winding prevents internal stress, keeping the tape lying flat without telescoping during automated high-speed unwinding.

FAQ
Q: How does this double sided film tape prevent adhesive oozing during long-term storage or die-cut slitting?
A: The high internal cohesion of the cross-linked acrylic formulation prevents cold flow and lateral adhesive migration under ambient pressure. Combined with a precision-slit polyester carrier, the roll edges remain non-tacky and clean, eliminating roll telescoping and matrix jamming during rotary die-cutting operations.
Q: Can this double coated polyester film tape securely join dissimilar materials with unequal CTE ratings?
A: Yes. The balanced shear cohesion of the acrylic adhesive absorbs shear stresses generated between metals and plastics during temperature fluctuations. This prevents joint detachment, substrate warpage, or bond line buckling when joining stainless steel panels to ABS or polycarbonate components.
Q: Does the solvent acrylic adhesive mass resist chemical exposure and industrial fluids?
A: The fully saturated acrylic polymer resists breakdown from motor oils, hydraulic fluids, cleaning alcohol, and mild chemical spray. The non-porous PET film backing forms an impermeable barrier, preventing fluid migration along the bond interface during long-term industrial operations.
