Abstract

Glove rejects can be loaded as filler in the formula (NR 100, ZnO 5, stearic acid 1, MBT 1, S 2.5, BHT
1 and calcium carbonate 40 phr) up to 100 phr to give good properties such as cure time, tensile strength,
300% modulus, elongation at break, tear strength, crack growth and abrasion index. However, scorch
time and extrusion quality show a shorter time and rougher surface with higher loading, respectively.
A recommended quantity for obtaining good properties in scorch time and extrusion process by garvey die
is 40 phr. Powder gloves show a different cure time and scorch time from chlorinated gloves but show no
significant changes in physical properties.
