FIELDS OF TESTING : Chemical & Mechanical

We carry out test on dry, raw natural rubber according to test methods developed by the Malaysian Rubber Board (MRB, formerly known as RRIM) and documented in SMR Bulletin No. 7 (Revised Edition) 1992. 
These methods are also adopted by most of the rubber producing countries nowadays.
