What is Double Sided Tape
Double-sided adhesive is a common adhesive product, consisting of three parts:substrate, adhesive, and release paper (film). Its working principle is to firmly stick two objects together through the viscosity of the adhesive. https://post.smzdm.com/p/arr34rp7/
Double-sided adhesive has a wide range of application scenarios. In the electronic market, it can be used to paste the parts of mobile phones, computers, digital cameras and other equipment.In the automotive market, it is often used in the automotive appearance of decorative strips and fixed parts, car labels, etc..In the home market, the adhesion of hooks, furniture, toys, crafts are inseparable from it.
Two main classification criteria:
Classification by substrate:
The substrate of double-sided adhesive includes cotton paper, PET, PVC film, non-woven fabrics, foam, acrylic foam, film and so on. In these substrates evenly coated on both sides of elastomer-type pressure-sensitive adhesive or resin-type pressure-sensitive adhesive, acrylic pressure-sensitive adhesive made of rolls or sheets of adhesive tape. No substrate double-sided adhesive is directly in the release paper (film) material coated with adhesive.
Classification by adhesive:
It can be divided into solvent-based adhesive tape (oil-based double-sided tape), emulsion-based adhesive tape (water-based double-sided tape), hot-melt adhesive tape, calendering adhesive tape, reactive adhesive tape and so on. Hot melt double-sided adhesive is mainly used for stickers, stationery, office, etc.; oil-based double-sided adhesive is mainly used for leather goods, pearl cotton, sponge, shoe products and other high viscosity needs of the goods; embroidery double-sided adhesive is mainly used for computer embroidery.
How to pick?
Consider the material of the object to be pasted:
Different materials need to choose different types of double-sided tape. For example, to paste plastic objects, you can choose PET double-sided tape. To paste metal objects, acrylic foam double-sided tape may be more appropriate. If it is to paste paper objects, cotton double-sided tape is a good choice.
Concerned about the viscous strength:
According to the weight of the pasted object and the requirements of the application of the environment to choose the appropriate viscous strength of the double-sided tape. For heavier objects or items that need to be fixed for a long time, you should choose a stronger adhesive double-sided tape, such as oil-based double-sided tape. However, for some lighter items or temporary adhesive needs, water-based double-sided tape and other relatively weak adhesive double-sided tape just can meet the requirements.
Consider the use of the environment:
If the use of environmental temperature is higher or lower, you need to choose the corresponding temperature resistance of double-sided tape. For example, double-sided tape used in high-temperature environments, should have good high-temperature resistance, such as high-temperature double-sided adhesive; double-sided tape used in low-temperature environments is necessary to ensure that it is still able to maintain good adhesion at low temperatures.
Attention to environmental protection:
In some of the higher environmental requirements of the place, such as children’s toys, food packaging, etc.. At this time, you should choose environmentally friendly double-sided tape, that is, solvent-free environmental protection adhesive or water glue made of double-sided tape to ensure the safety of applying.
