COMPOUND PEBD PRETO (TC 9008) IS A LOW DENSITY POLYETHYLENE COMPOUND, WITH HIGH MOLECULAR WEIGHT AND MOLECULAR WEIGHT
DISTRIBUTION, SPECIALLY DEVELOPED TO WIRE & CABLE JACKETING.
THIS GRADE SHOW GOOD EXTRUDABILITY, MECHANICAL RESISTANCE AND STRESS CRACKING. IT CONTAINS CARBON BLACK TO RESIST
PHOTODEGRADATION AND HIGH UV ABSORPTION COEFFICIENT.
ACCORDING TO ASTM D 1248:04, TC9008 IS IC-5 CLASSIFIED, E9 DEGREE, J4 E W4.

CAS REGISTRY NUMBER: 9002-88-4.

LDPE IS NOT A HYGROSCOPIC MATERIAL. HOWEVER, CARBON BLACK, WHICH IS USED AS AN ANTI-UV ADDITIVE, ABSORBS MOISTURE FROM THE
ENVIRONMENT. THEREFORE, ALL HDPE CONTAINING CARBON BLACK IN ITS COMPOSITION MUST BE DRIED BEFORE USE. THE DRYING PROCESS
MUST BE MADE AT LEAST FOR 2 HOURS AT 90°C. UNDER THESE CONDITIONS THE AMOUNT OF MOISTURE DECREASES TO VALUES THAT WILL NOT
INTERFERE IN THE PROCESSABILITY OF THE RESIN. THE USE OF THIS RESIN WITHOUT PREVIOUS DRYING MAY CAUSE PROBLEMS IN THE FINISHED
PRODUCT, SUCH AS BLISTERING AND/OR ROUGHNESS OF THE SURFACE.
