2021/03/01

      At present, many customers apply PUR bulk melter to sealing performance, why?

      PUR bulk melter is also known as moisture curing reactive polyurethane hot melt adhesive. It encounters moisture in the air and will undergo an irreversible crosslinking reaction. Therefore, during the use of the PUR bulk melter, the sealability of the adhesive is very important.

      The PUR bulk melter is an automatic PUR special glue application equipment. There are currently 5 gallons and 55 gallons. The precision metering pump forms a smooth surface, beautiful appearance, strong resilience, good dust and waterproof performance, and sealing protection level. High and environmentally friendly hot melt adhesives make the lid more precise and faster.


       We know that the processing size and accuracy requirements of the sealing ring are extremely strict. At present, there are many models and shapes on the market, and the selection range is also large. It often needs to be customized separately. Customization often requires re-opening the mold, which leads to an increase in production costs. , Is not conducive to the long-term development of the enterprise.
