Heat sensitized dipping with radiation vulcanized natural rubber latex
Material type:
TextPublication details: Rubber India 2001Description: 12-JulSubject(s): Summary: Dipping is an important process in latex technology for the production of articles like examination gloves, teats, condoms, catheters etc. Straight dipping is used for the production of very thin walled articles. Coagulant dipping provides little more thicker articles; but a number of dips are needed to achieve desired thickness. The use of radiation vulcanized natural rubber latex (RVNRL) is becoming more popular in areas where dipped products free from type IV allergy, carcinogenic nitrosamines and very low in type I allergy are required. The common dipping processes with RVNRL are straight and coagulant dipping. This paper describes the results of heat sensitive dipping experiments for obtaining dry deposits of thickness 2-4 mm in single dip. The effects of dwell time, temperature of the former and maturity of latex compound at the time of dipping have been studied. The storage stability of the dry latex compound and the tensile properties of the dry deposits are good.
