Jowat Unveils Polyolefin HMAJowat launches Jowat-Toptherm® 221.00, a polyolefin hot-melt adhesive (HMA) for automatic edgebanders. Jowat-Toptherm® 221.00 has wide range of applications, e.g. for edgebands made of pressure laminates, PVC, ABS, PP, resinated paper, veneer, and solid wood.

Heat resistance with Zero bondline

Advantages of Jowat-Toptherm® 221.00:

  • Heat resistance: Meets high heat resistance requirements (e.g. kitchen furniture) due to a higher melting range at over 100 °C
  • High yield: The considerably reduced density of polyolefin hot melt adhesives facilitates low application amounts
  • Zero bondline: The transparent adhesive coupled with low application amounts facilitates hardly visible adhesive joints (“optical zero bondline”)
  • Stability: The high thermal stability of PO hot melt adhesives reduces the risk of charred adhesive in the melt reservoir and extends cleaning intervals considerably

Popularity of HMAs based on polyolefin (PO) has increasingly grown, since of thermoplastic hot melt adhesives in the late 1980s. It started with the demand for a superior heat resistance compared to the then-established ethylene vinyl acetate hot melts and now polyolefin hot melts offer a variety of substantial advantages.

Due to the purely physical setting process, PO hot melt adhesives are easy to handle and do not require any special application equipment. However, they facilitate considerably higher heat resistances compared to EVA hot melt adhesives. Coupled with low-adhesive consumption and very clean processing, these benefits have made modern PO hot melt adhesives an attractive alternative for edgebanding as well as profile wrapping applications.
