Types of double-sided tape

We can use double-sided tape in all major occupations. The results that may be used in different occasions may not be satisfactory. So why are there such big distances for double-sided tape?

The main reason for double-sided tape is that the glue used is very different. The common glue moisture is double-sided adhesive oil glue and water glue, hot-melt pressure-sensitive adhesive. What about sensitive adhesives? Now let ’s briefly introduce their characteristics:

Double-sided adhesive glue is made by emulsifying acrylic or polyurethane resin through special emulsification equipment with water as solvent. Its advantages are: many types, environmental protection, and low price. Nowadays, many coatings are made of water-soluble adhesives, such as general water-soluble PA, water-soluble PU, as well as film adhesive, oily wax feeling, color shaving slurry and other functions Sexual paste. Water solubility will be the direction of future coating due to its functionality, environmental protection, and low price. The defects are poor film formation, poor washing fastness, PU can not be pasted with hot air glue, and it is not suitable for foam products such as sponge and foam;

Double-sided adhesive oil adhesive is made by dissolving acrylic or polyurethane by using oily solvent (toluene, DMF, butanone, etc.) as solvent. Its advantages are good film-forming property and good fastness. PU can be pasted with hot-air adhesive, which is currently widely used coating adhesive. The defect is because of the use of oily solvents, so there is a shortage of environmental protection, especially now that the price of oil has increased, causing the price of oily solvents to rise all the way. The environmental protection is unqualified. In addition, with the further improvement of environmental protection regulations in various countries, the environmental protection requirements for coating adhesives are becoming higher and higher.

Double-sided adhesive hot-melt pressure-sensitive adhesive is a type of pressure-sensitive adhesive, mainly made of synthetic rubber mixed with resin and rubber oil and heated to a molten state, and then coated on cotton paper, cloth or plastic film and other substrates A new type of adhesive tape, low cost is its advantage, the defect is that the viscosity is significantly affected by temperature. Mainly used for various types of box sealing, box sealing, paper product packaging, beverage bottle labels, sealing aluminum foil, flexible packaging and other packaging; environmental protection paper pallets, etc., adapting to various materials.

Therefore, when we buy double-sided tape, we must not only look at the cheap price, but to know the environment in which we use it, and choose the type of double-sided tape suitable for our enterprise.
