Datasheet: RW 70
RW 70
High Strength Hot Cutting Wire.
The hot cutting wire RW 70 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
