Excelta is range of high end hotmelts which are based on a polymer range obtained through a new polymerisation technology, known as metallocene catalyst polymerisation. The metallocene polymer has some unique properties like an outstanding heat stability, narrow molecular weight distribution and a sharp melting point.
The current trends in the market of packaging hotmelt users are:
- total cost reduction
- rationalisation of purchased materials (wider operating window)
- use of same materials for domestic and export
- increase production line speeds
- trouble free production lines
- low maintenance costs
- safety issues (e.g. fumes)
The use of this new polymer technology in Excelta hotmelts results in:
- outperforming heat stability
- prevention of char forming
- viscosity stability at working temperature
- light initial colour and colour stability
- superior machineability
- flowing performance and superior jetting
- potential higher production line speeds
- reduced consumption of hotmelt
- excellent bonding
- improved fibre tear compared to EVA based products
- unparalled adhesion to difficult substrates like PE and PP
- low and high temperature resistance
- versatility
