The material of PVC filler will be non-groscopic and solid or hollow in nature as perthe requirement. The dimensions of material will be stable with no joints in filler in the same coil. Each coil will have uniform diameter throughout the length. Below are the specified criteria for PVC filler.
Advantages
Surface will be smooth
Ovality will not more than 15 %. Ovality in diameter = (Dmax- Dmin/ Dmax )X100
Tolerance on diameter is ± 2.5 %
The Filler shall be wrapped round its own diameter to form a close helix of 6 turns and unwrapped
Cracks should not be appearing.

PP Fillers
The PP Fillers are play an important role during twisting of cores in cable,PP Fillers are used to fill the gaps between the cores of cable. - Oorja PP filler is manufactured using latest and precise technology.
Material of filler is Polypropylene fibrillated Yarn (in uniformly twisted/bunched). - Oorja PP filler material is compatible with the temperature of the cable which has no deleterious effect on any other component of the cable.

TYPES OF TAPES
Insulating Tapes
It is a type of pressure sensitive tape and can be made of many plastics but vinyl is most favored because of its advantages. It stretches well and prevents possible electrocution if live wires are touched.
Water Blocking Tapes
These tapes are used to basically prevent water entry into optic fiber and telecom cables. It gives long term performance as compared to traditional filling jellies in optical fiber cables.
