1, double-sided tape with non-woven fabric substrate
Non-woven double-sided adhesive tape has good adhesiveness and processability, generally long-term temperature resistance can reach-10- 120℃, short-term temperature resistance can reach 140℃, and the thickness is generally about 0.08-0.20 mm. It is suitable for nameplates, plastics, automobiles, mobile phones, electrical appliances, sponges, etc.
2. Double-sided tape without substrate
The double-sided adhesive tape without substrate has excellent adhesion effect, excellent waterproof performance, good processability and temperature resistance. The short-term temperature resistance can reach 204-230℃, and the general long-term temperature resistance can reach 80- 120℃. The thickness is generally about 0.05-0. 13MM, which is suitable for bonding nameplates, panels and decorative parts.
3, PET double-sided tape
PET double-sided adhesive tape has good temperature resistance and strong shear resistance, generally, the long-term temperature resistance reaches 50-90℃, the short-term temperature resistance reaches 1 10℃, and the thickness is generally 0.048-0.2 mm. It is suitable for sticking nameplates, liquid crystal displays, decorations and decorative parts.
4. Foam double-sided adhesive tape
Foamed double-sided adhesive tape has the advantages of softness, good adhesion, good initial adhesion, good solvent resistance and ultraviolet resistance. Its general thickness is about 0.4-3.0MM, and its short-term temperature resistance reaches-10-10℃, and its long-term temperature resistance reaches 50-80℃. Suitable for bonding air conditioners, office furniture and communication products.
5, VHB acrylic tape
VHB acrylic adhesive tape has excellent adhesion, weather resistance, water resistance and high temperature resistance. The thickness is generally 0.3-3.0 mm, which is mainly used for structural bonding and fixing of various decorative parts and hardware of automobiles, sealing assembly of building glass and doors and windows, installation and fixing of elevator wallboard, installation and fixing of various industrial signs, and fixing of decorative strips of household appliances.

Matters needing attention of double-sided adhesive tape
1. Some papers are easy to peel off when pasted, but it is difficult to peel off after one cycle (24 hours) and cannot be peeled off after three cycles.
This kind of release paper is mainly unstable, the paper density is not good, the coating is uneven, and the permeability resistance is poor. The glue can penetrate into the release paper for a period of time, so it can't be peeled off! Therefore, it is necessary to replace the paper with good density, good paper, uniform silicon coating and relatively stable paper as the backing paper.
2. The peeling property of imported double-sided adhesive tape is poor, and many tapes will have this phenomenon, because the physical properties of imported double-sided adhesive tape are different.
Conventional ones mainly include 3M, Nitto, Sony, Jishui, TESA, etc. There is no base material, and many die-cutting manufacturers use backing paper for convenient die-cutting processing, which leads to poor peeling. Therefore, when the viscosity of the tape is quite different, it is necessary to judge the viscosity of the tape and use the backing paper alone.
Thirdly, this kind of adhesive tape can be used for pasting at ordinary times, but it is difficult to discharge waste after die-cutting or because the die-cutting product is too small to peel off.
In this case, we should pay attention. Some die-cutting products are easy to pick up in the process of waste discharge, indicating that the peeling force is too light, so you can choose a slightly heavier one to try.
It's normal if it can't be peeled off or it's not good (especially if there is no substrate), because the area of die-cut products is too small and peeling is easy to cause deformation if the peeling strength is not light enough, so we must use lighter release paper.
