About PVC Compounds:
Cable PVC compounds are thermoplastic materials derived from
processing polyvinylchloride compositions, produced as granules.
Various properties are imparted to compounds depending on
applications and item operation conditions. This is achieved by
using plasticizers, stabilizers and modifiers in various
combinations in compositions.
PVC based plasticizers have considerable mechanical strength and
water resistance, high thermal resistance to low temperatures, good
insulation properties, insoluble in gasoline and kerosene,
abrasion, acid and alkali resistant. PVC based compounds are
readily welded and glued.
Cable PVC compounds are use in the cable and conductor industry for
manufacture of insulation and protective wire and cable sheaths.
The main final consumers of the PVC based cable and conductor
products are energy and construction industries.
Here are two examples:
Softener formulation adjustment can raise the continuous operating
temperature limit to 105°C.
Aluminium trihydroxide (ATH) additive can systematically reduce
flammability and smoke formation. Regulatory authorities such as
the VDE, EN or UL issue standardized property profiles for
insulation and coating compounds.
