As a mature and rel iable process, physical foaming has beenfully accepted by the cable market and has been widely used inactual production instead of chemical foaming process.
Generally used foam insulation materials, inc luding polyethylene (PE) and fluorine plastic (FEP), can be used forcommunications cables, data cables, coaxial cables and radiofrequency cables. Because of the high degree of foaming, thecomposition and design of the physical foam production linesare more complex than chemical foams, such as longer extrudersand gas injection systems.
One of physical foaming is Physical Foaming Insulation Materials Mixed With Activators.It is a kind of high molecular weight polyolefin, processing temperature, on the basis of the the typical for appropriate adjustments.
