Filler
Right!
Filler strips are flame-resistant or non-flame-resistant fillers suitable for use in forming various cables, and are generally fan-shaped.
Features
1. The filling strip uses various polyolefins as the main material, and adds certain plasticizers and flame retardants, and is extruded through foaming and plasticizing. It is a rare non-hygroscopic filling material for cable production.
2. The filling strip is shaped and stable, and has high mechanical strength, which can fully ensure that the structure of the cable is stable and the appearance is round.
3. The density is small, which can effectively reduce the manufacturing cost and weight of the cable.
4. The oxygen index of the flame-retardant filling strip is as high as 30 or more, which can effectively improve the flame-retardant performance of the cable.
5. According to customer's requirements, it can also process filler strips such as polyvinyl chloride.
Filling strips should be stored in a clean, cool, dry and ventilated warehouse.
The specifications of the filling strip are different for each company, and the general specifications are
