Field latex is a white or slightly yellowish opaque liquid with a specific gravity, which varies between 0.974 and 0.986. It is a weak lyophilic colloidal system of spherical or pear shaped rubber globules suspended in an acquiesces serum. Field latex is centrifuged to manufacture latex concentrated of 60% rubber content. Centrifuged latex is commercially available in two different varieties, one with high ammonia (above 0.60%) and the other with Low Ammonia (less than 0.30%). It also contains secondary preservatives like TMTD (0.0125%) and zinc oxide (0.0125%). Grading, packing, and making of centrifuged latex are as per specifications prescribed in IS 5430.
