Analysis Of Chemical Properties Of EVA Hot Melt Glue Sheet
- Sep 06, 2017 -

      Hot melts is a kind of plasticity adhesive, it is in a certain temperature range of its physical state with the temperature change, and its chemical properties unchanged, it non-toxic tasteless, belong to environmental-friendly chemical products. So it is one of the more commonly used adhesives today, but how to choose the right hot melts? The following aspects are only for reference: The color of hot melts: if the substance itself has no special requirements for color, then you can use yellow hot melts, generally speaking, the stickiness of yellow hot melts is better than that of white.EVA Hot Melt Glue Sheet
      Bonded Substance surface Treatment: Hot melt adhesive on the surface of the adhesive substance no other adhesive is so strict, but the surface of the sticky substance dust, oil should also do appropriate treatment, so that hot melts to play a better bonding effect. Bonding time: Bonding Fast is a major feature of hot melts, hot melts adhesive bonding time is generally only 15 seconds or so, with the wide application of modern production line operation, the bonding time of hot melts is higher, that is, the shorter the better, such as book binding and speaker manufacturing to hot melts bonding time requirements in about 5 seconds.EVA Hot Melt Glue Sheet
      Hot melts on the temperature sensitivity: the temperature reached a certain degree, hot melts began to soften, lower than a certain temperature, hot melts will become brittle, so choose hot melts must be fully considered the temperature of the product environment changes. Five, viscous: the viscosity of hot melts early viscous and late viscous, only the early viscous and late viscous consistency, can make hot melts and the adhesive substance maintain stability.

       Of course, in the process of hot melt adhesive production, should ensure that it has the oxygen resistance, the halogen resistance, the acid-alkaline and the plasticity and so on, is bonded substance material's different, the hot melts the stickiness which plays the different, therefore, should according to the different material choice hot melts the rubber.EVA Hot Melt Glue Sheet
