Copolyester
The copolyester series ROWALIT® 400 is applied in the apparel industry and steadily expanding in technical items. They cover a melting range of 80-135°C.
Copolyester hotmelt adhesives offer good bond strength and wash resistance on PES and traditional blends like PES/Cotton textiles. Dry cleaning resistance is limited.
