    In the glove manufacturing industry, quality of the centrifuged latex is highly concerned. Properties of the centrifuge latex can be deviate from the acceptable level with the maturity. Therefore study of the variation of both chemical and physio mechanical properties of centrifuge latex with the maturity is very much important for the manufacturers of latex products ( Riyajan, 2009). Normally it is not possible to obtain the required amount of field latex for the centrifugation due to the rainy season in the country. But the manufactures of latex gloves have to maintain their production without discarding any order of the buyers. To overcome this problem, manufacture has to concentrate an alternative way for the glove manufacturing. Therefore low matured latex is also used in some extent while mixing with the matured latex during the compounding. Main objective is to determine the usage of low maturity latex (before 21 days maturity) for the production of house hold glove manufacturing while studying the properties of centrifuged and compounded latex at different maturity stages. Methodology: Centrifuged latex was obtained from the Centrifuge unitof Lalan Rubbers pvt Ltd at Warakapola. Freshly produced centrifuged latex was selected to conduct the research activities. Different maturity periods were set as treatments for research study and seven treatments were applied to get results. During this experiment, changes of both chemical and physiomechanical properties of centrifuged latex were evaluated at different maturity stages. Experiment was started after 5 days maturity of centrifuged latex and continued up to 65 days maturity periods.
