# Specific heat capacity of filler

Specific isobaric volumetric heat capacity of filler material per K at 20$^{\circ}$C

The values are taken from standard IEC 853-2 Ed.1.0 plus following additions:

• Values for fibrous polypropylene (fPP), polyolefin copolymers (fPOC), polyethylene (fPE), and polyvinyl chloride (fPVC) are assumed to be 70% of the corresponding solid material (refer to $\sigma_ab$)
• Plastic rods are considered to have 30% air-space, the rest PVC
• Plastic tubes are considered to have 50% air-space, the rest PVC
• Twisted yarns are assumed to be similar to jute
• Tapes are assumed to be similar to jute
