Latex & Rubber Analysis

Natural rubber has tremendous commercial applications and it is with economic and technological importance. Its characteristics of waterproof, high strength, flexibility, and elasticity offer many unique characteristics not found in other raw materials like petroleum based products. Today, natural rubber is an important material in many key industries worldwide such as automotive, electrical, electronics, pharmaceutical, medical industries, etc.

To ensure the quality of dried natural rubber meets its required specifications, the Malaysian Rubber Board (MRB) has regulated the testing of dried natural rubber before being certified as SMR (Standard Malaysian Rubber). This certification has to be conducted prior to import and export activities. SMR certification is to be conducted by laboratories under MRB or authorized independent laboratories nationwide and, Eurofins North Malaya Laboratory is one of them.

Under requirement by MRB, the parameters to be tested for SMR certification are dirt, volatile matter, ash, nitrogen, rapid plasticity, and plasticity retention index, Mooney viscosity, and rheometric cure test by SMR Bulletin no. 7 (Rev. ed. 2018). Besides these basic tests required for SMR certification, Eurofins North Malaya Laboratory is also performing other general studies for SMR (density determination, bale packing bag materials identification, vulcanization studies, and foreign substance identification and etc), specification testing for TSR (Technically Specified Rubber) and specification testing for rubber latex.

Range of Rubber / Latex Testing Parameters included:

• Dirt

From serving the rubber industry in rubber testing for the past 30 odd years, we have learned the legislative and specification requirements imposed by the regulatory bodies; and we feel privileged for being able to play a part in the import-export of one of the major commodities of Malaysia. Whether you are a newcomer or an existing player in the rubber industry, our expertise and experiences will be of use to you.

Eurofins North Malaya able to provide Standard Reference Materials (SRM) which play an important role within a broader quality assurance program especially in the rubber industry. It serves as an important tool for the implementation of numerous aspects as following:

• Quality measurements
• Validation of methods
• Calibration
• Estimation of measurement uncertainty
• Training and internal quality control
• External proficiency testing or inter-laboratory testing

Specification of Standard Reference Materials as following:
