What is the difference between 3M double-sided tape with and without substrate?

Double sided adhesive tape with base material: it is a roll or sheet adhesive tape made of cotton paper, pet, PVC film, non-woven fabric, foam, acrylic, film, etc. and evenly coated with elastic pressure-sensitive adhesive or resin pressure-sensitive adhesive and class C pressure-sensitive adhesive on both sides. It is composed of base material, adhesive and isolation paper (film).

No substrate double-sided adhesive: it is a roll or sheet adhesive tape made of adhesive (elastic pressure-sensitive adhesive or resin pressure-sensitive adhesive, class C pressure-sensitive adhesive, etc.) coated on release paper (film) materials. It is composed of adhesive and isolation paper (film). The color of the tape is transparent, and the common thickness specification is 0.06-0.13mm, which has excellent bonding effect.

No base material double-sided adhesive fruit, Double Sided Tape which can prevent falling and excellent waterproof performance, good heat resistance, good dimensional stability, thermal stability, chemical stability, good initial viscosity and holding viscosity; It can be applied to a wider temperature range and harsh environment; The long-term temperature resistance is 80-95 ℃, and the short-term temperature resistance can reach 180-205 ℃;

The products are widely used for all kinds of foam lamination, metal nameplate, automobile, electronic film tape, film switch, Double Sided Tape furniture plastic, panel, glass, wood chip, sheet adhesion, document adhesion, elevator, electronic industry assembly, rough surface, smooth surface, artistic material lamination, and sporting goods accessories.
