SOIL BURIAL RESISTANCE OF VINYL CHLORIDE PLASTICS
SOIL BURIAL RESISTANCE OF 21 FLEXIBLE, SEMIRIGID, AND RIGID POLY (VINYL CHLORIDE) FORMULATIONS USED AS ELECTRICAL INSULATIONS OR CABLE JACKETS WAS STUDIED. DETAILED DESCRIPTIONS OF TEST PROCEDURES AND EVALUATIONS ARE GIVEN. BURIAL (4 YEARS) WAS IN GEORGIA (SOIL PH 5.2) AND NEW MEXICO (SOIL PH 8.2). PERFORMANCE WAS AFFECTED MORE BY COMPOSITION VARIABLES, PARTICULARLY CHOICE AND CONCENTRATION OF PLASTICIZERS, THAN BY BURIAL LOCATION, DEPTH, ELECTRICAL POTENTIAL, OR METALLIC CONDUCTORS USED. SUSCEPTIBILITY OF THE VARIOUS PLASTICIZERS TO ATTACK DID NOT CORRELATE WELL WITH PREVIOUS DETERMINATIONS OF THEIR FUNGUS RESISTANCES. PLASTICIZERS - E.G., TRICRESYL PHOSPHATE, POLYESTERS, NITRILE RUBBER, AND DIPENTAERYTHRITOL ESTER, THAT ARE NONMIGRATORY AND/OR INHERENTLY MICROBIAL RESISTANT - GAVE THE BEST PERFORMANCE. PHTHALATE PLASTICIZERS WERE MORE SUSCEPTIBLE TO ATTACK, BRANCHED-CHAIN TYPES SHOWING SOMEWHAT BETTER PERMANENCE THAN THOSE PREPARED FROM NORMAL ALCOHOLS. /AUTHOR/
