Longyan production PUR glue direct longyan production PUR glue direct development direction editing butyl acrylate: molecular formula: C7H12O2; CH2CHCOO( CH2) 3 ch3, molecular weight: 128. 17 colorless liquid. Vapor pressure: 1. 33个kpa / 35。 5℃; Flash point 37 ℃; Melting point - 64. 6℃; The boiling point of 145. 7℃; Solubility: insoluble in water, but soluble in ethanol, ethyl ether; Density, relative density ( Water = 1) 0. 89; Relative density ( Air = 1) 4. 42. Stability: stable. Tag ( Flammable liquids) ; Main application: used as intermediates in organic synthesis, adhesive, emulsifier. Main features editor (2) the high oil content,> 15%) The outermost layer of skin, prevent water splashing of the processed material and some bounce big hard material, we do not recommend using water-based glue; 7. Water-based glue then problems in use process analysis of structural conductive adhesive structure refers to the material itself contains conductive functional groups, and doped conductive adhesive is added in the adhesive has the conductivity of the material. 1. Non-toxic, no smell, high transparency, no yellowing; Longyan production PUR glue direct if you are unwell seek immediate attention should be paid to prevent frostbite, will destroy the performance under 0 ℃ storage for a long time, many different kinds of pressure sensitive adhesive, can be classified from different angles. A lot of customers on the hot melt adhesive machine working principle is not clear, there will be various aspects. 2. Soft, good elasticity, resistance to kink deformation; Introducing polar group in molecular OH, COOH) that produce hydrogen bonding between molecules, and slightly crosslinked network structure, make the copolymer molecular weight distribution is more wide, and broad molecular weight distribution of copolymer adhesive easier pressure sensitive adhesive between the three performance good unity, the above experiments also proves this point. 3. No crack, long service life, cold resistant high temperature; Longyan production PUR glue direct a, hot melt adhesive can condense into a solid, the high temperature of liquid condenses into solid state even in a period of time, still with a high temperature, once touch a person's skin, can cause serious injury. 4. Have a higher resistance to tear strength and superior electrical properties; Longyan production PUR glue direct technical indicators PH 6. 5 to 7. 5 if the glue on the skin, can clean water and soap. High molecular weight polymer part determines the pressure sensitive adhesive with viscous force, while part of the low molecular weight contribution to the viscous force and peel strength comparison.
