Jiujiang PUR glue complaints jiujiang authorized the selection of catalysts for PUR glue complaints not only depends on the kinds of monomers, but also depends on the adhesive drill agent USES. 5, good quality hot melt adhesive with heat resistance performance, can put the hot melt adhesive in zero or more than 40 degrees respectively environment for testing, if there are brittle, soft gelatin said quality is bad now. Melting temperature: 120 - 160℃4. Have a higher resistance to tear strength and superior electrical properties; Acrylic adhesive is a kind of structural adhesives, cement with wide range, including most types of plastic, slightly and do not make processing of metal processing. At present good quality hot melt adhesive can be used in the field of industrial manufacturing, heat resistance performance and flame retardant performance is guaranteed, the current can reach the quality requirements must be big brand products, such as ke, Moore, focus on the study of the hot melt adhesive, provide customized hot melt adhesive application solutions, wide range of USES, can be applied to new energy, military industry, aviation, shipbuilding, electronics, automobiles, instrument, power supply, high iron, and other areas of the industry. Vinyl acetate copolymer ( EVA) , polyurethane, polyester, polyvinyl chloride (PVC) resin can make all kinds of pressure sensitive adhesive. Polyurethane type: single-component or bi-component products, for most materials have good bonding performance, and wear resistance. Although some hot melt adhesive at the time of operation will be some smell, but is completely disappeared after curing, so the hot melt adhesive is safe, can be used in electrical parts of adhesive. Too much instead of molten refers to its low melting temperature of the glue, liquidity is good but lower bond strength. 1, EPE packaging industry, electrical appliances, shockproof anti-throw EPE packaging materials packaging assembly parts, electrical appliances manufacturer for rubber end users without peculiar smell, and in the production of EPE packaging manufacturer assembly process, coating machine is open, a local heating temperature is high, production workers allergic to special smell, think there's a smell is poisonous, the influence is healthy, require a safe working environment, so the smell of extremely strict requirements are put forward for hot melt adhesive, require hot melt adhesive has no smell. Jiujiang authorization PUR glue similar complaints and poly phthalein amine, homopolymer of cool rarely used in hot melt adhesive machine. 1, the moisture in maintenance pur reactive polyurethane hot melt adhesive machine before work, must first put pur moisture of reactive polyurethane hot melt adhesive machine to cut off the main supply power and connection outside, shall not be charged. 2, sanitary products industry: in recent years, the baby diapers, sanitary napkin, adult MATS and other health care products industry puts forward very high requirements on the smell of hot melt adhesive, require hot melt adhesive has no smell.

So in order to cater to the terminal customers, health supplies manufacturers require health supplies of raw materials manufacturers of materials, which is understandable. Very good flexibility at low temperature, the operating temperature of 250 of ( 121oC) 。 Can be divided into two components of catalytic curing, one-component UV curing or thermal curing. Jiujiang authorization PUR glue complaints about its choice of AIDS, should choose to ethylene vinyl acetate with appropriate proportion.
chemical company chemical factory has gained a lot of popularity over the recent past.
