Our major industries can use double-sided tape, the effect may be used in different occasions, the result may not be satisfied, then the double-sided tape Why is there such a big gap?
The main reason is the double-sided adhesive glue used is not the same, the common glue into oil-sided adhesive glue and water glue, hot melt adhesive, then how to distinguish between oil-sided adhesive glue and water glue, hot melt ? pressure-sensitive adhesive it now we briefly explain their characteristics:
Double-sided adhesive glue is water as a solvent acrylic or polyurethane resin emulsion through specialized equipment, emulsion formed. Its biggest advantage is: varieties, environmental protection, low price, there are many coatings are water-soluble glue, for example: general soluble PA, as well as a water-soluble coating PU glue, oil feeling a sense of wax, scrape pulp color paste and other functions. Its low water-soluble functional, environmental protection, and the price will be the future direction of the coating. The disadvantage is that a film is poor, poor wash fastness, PU can not paste hot glue, not fitting foam, foam and other foam products;
Oil is a double-sided adhesive glue of oily solvents (toluene, DMF, methyl ethyl ketone, etc.) as a solvent, acrylic or polyurethane and dissolved. The advantage is that the film is good, good fastness, PU can paste hot glue, it is currently widely used plastic coating. The disadvantage is that due to the use of oil-based solvent, so that the lack of environmental protection, especially now that oil prices, leading to sharp increase in oil prices had a solvent, most plastic coating because the cost is too high, so the use of a relatively poor oil solvent, resulting in environmental non-compliance, in addition to further improve the countries with environmental standards, so the plastic coating of increasing environmental requirements.
Double-sided pressure-sensitive adhesive is a hot melt pressure sensitive adhesive, and then coated on a substrate tissue paper, cloth or plastic film made mainly a mixture of synthetic rubber and resin and rubber oil heated to a molten state solution a new type of adhesive tape, low cost is its biggest advantage, the defect is obvious viscosity affected by temperature. Mainly used for various sealing, seal boxes, paper packaging, labels for beverage bottles, sealed foil, flexible packaging and other packaging; green paper pallets, etc., to adapt to all kinds of materials.
Double-sided tape so we buy when we must not only look cheap, and to know their own use of the environment, we choose the right kind of business use of double-sided tape.
