ABSTRACT :
The experience gained in the processing and usage of Technically Specified Rubber (TSR)since its introduction in India in 1974 is discussed. The suitability of a locally designed equipment for processing 10 tonnes of TSR per day and for doubling the production is examined,and the advantages and difficulties in regard to processing different grades of TSR are evaluated.Processing of latex into grades equivalent to SMR 5L was easily achieved,but processing coagulum into TSR grades initially gave unsatisfactory results.This has now been overcome with careful sorting of the material.,generous soaking in water combined with agitation and macerating and creping the material twice over.The need for laboratory facilities to test critical properties of the various grades and the special requirements for packing into 25 kg bales are discussed in relation to increasing production.It is concluded that backed by a consumer advisory service t the potential for TSR consumption can be effectively increased as revealed by market sentiments and it is anticipated that by 1980 a major proportion of Indian natural rubber will be processed as Technically Specified Rubber.
