How to distinguish between oil double-sided adhesive glue, glue and hot melt pressure sensitive adhesive

Double-sided adhesive types according to their different can be divided into double-sided adhesive glue series oil glue and hot melt pressure sensitive adhesive glue, so how do you distinguish double-sided adhesive glue, aqueous glue, hot melt pressure sensitive adhesive? Following a brief introduction of their respective features:
Double-sided adhesive glue
Based on water as the solvent will or polyurethane acrylate resin through specialized emulsification equipment, emulsifying and into. Advantage is: many varieties, environmental protection, low prices, now there are a lot of coating is done with water soluble glue, such as: general water-soluble PA, water soluble PU and leather adhesive, oil wax feeling, the feeling of color paste and other functional material. Water soluble with its functional and environmental protection, and the price is low, will be the future direction of coating. Defect is: poor film-forming, washing fastness, PU can't stick hot glue, unfavorable laminating sponge, foam and foam products.
Double-sided adhesive oil glue
Oily solvent (toluene, DMF, butanone, etc.) as solvent, dissolve or polyurethane acrylate. Its advantage is good film forming, good color fastness, PU can stick hot glue, is the current commonly used coating glue. Defect is due to the use of the oily solvent, so environmental protection lacking a bit, especially now that oil prices, oil solvent prices soaring all the way, most of the coating glue due to the cost is too high, so use more bad of the oily solvent, leading to environmental protection is not up to standard, in addition with the national environmental standards to further improve, so for environmental requirements of the coating adhesive is higher and higher.
Hot melt pressure sensitive adhesive
Is a kind of pressure sensitive adhesive, is mainly composed of synthetic rubber and resin and rubber oil mixture heating molten state and then coated on cotton paper, cloth or plastic film, such as base material and made a new type of adhesive tape, on the advantages of low cost is the biggest defects is affected by temperature is obvious adhesive. Mainly used for all kinds of sealing, sealing box, paper packaging, beverage bottle label, aluminum foil sealing, flexible packaging and other packaging; Environmental protection paper pallet, etc., to adapt to all kinds of material. Sealing glue for all kinds of polishing, polishing, pressure light, PP compound such as PET, PP transparent box, adhesive film, non-woven products, cosmetics box, packaging, food packaging, cigarette packaging, furniture edge banding tetra beverage packaging, assembly, electronic industry, automobile interior trim seal, headlights, windshield assembly, etc.), non-woven pads, diapers, diapers, insoles, disposable supplies, paper coating composite trademark, label double-sided adhesive tape, glue rat board, flypaper, wooden floor and carpet glue, bandages, medical athletic tape, color box packaging, carton packaging, back adhesive glue cingulate and other difficult sticky material has strong adhesive force; Good thermal stability, no impurities, good operation; Excellent weatherability; Aluminum foil sealing characteristics of the hot melt adhesive unique water resistant, waterproof.
