Abstract

Low protein latex (LOPROL) developed at the RRIM has been found to be suitable for factory scale production of examination gloves. Both prevulcanised and post vulcanised formulations can give satisfactory tensile properties; the latter requiring modifications of the formulations and compounding techniques. A post vulcanised formulation was used in the factory run. Unaged tensile strength of these gloves was in the region of 25 MPa - 27 MPa and a retention of more than 90 was obtained when they were aged at 70 C for 7 days and 100 C for 1 day. Although the mechanical stability time of LOPROL has been reported to be lower than 650 s continuous stirring of a compounded LOPROL caused a marginal increase in coagulum content after 7 days compared with HA latex treated in the same manner. Short on-line wet leaching time of about 1 min gave soluble protein contents of the LOPROL gloves to be 0.1 mg/g film. When these were dry leached for 30 s the soluble protein contents further decreased to between 0.03 mg/g - 0.06 mg/g film.
