The chemical name of sponge is polyurethane plastic foam, which can be divided into rigid foam, soft foam, high-density foam and low-density foam. It is widely used in clothing, footwear materials, automobiles, aviation and other industries. Our hot-melt adhesive products are widely adopted and used for pasting with sponge products of various materials due to their environmental friendliness and high-efficiency and convenient construction.
In shoe material lamination, Boiling has a special hot-melt adhesive for shoe material lamination, which can well meet the composite application of soft foam and low-density sponge. For hot-melt adhesive for sponge coating and lamination, it is relatively easy to match on hard and high-density sponge. However, on soft and low-density sponge, it puts forward requirements for our hot-melt adhesive - it must have good fluidity so that the glue can easily penetrate into the sponge. In addition, the coated product should have good adhesion to the release paper and cannot be delaminated, which requires good initial adhesion of the glue. The seemingly simple sponge has caused many peers to suffer a lot. Through repeatedly simulating the actual usage scenarios of customers, our Boiling technicians have developed the BL-702A product, which has been praised by customers once it is launched.
The "call" of Boiling hot-melt adhesive to sponge can fully meet the pain points in sponge application - the finished product does not delaminate and maintains long-term non-drying performance. I believe there are still many materials "calling" for our hot-melt adhesive products. This requires our hot-melt adhesive peers (enterprises) to work together and make progress together!
