Datasheet: RW 118

RW 118

The hot cutting wire RW 118 has high strength at elevated temperatures and is used for cutting polystyrene (EPS) and or heat-sealing polypropylene bags.

To achieve the best cut, adjust the temperature and cutting speed. The material type and it’s density will influence the cutting speed.

Available in all profile options
