Amorphous silica and carbon blacks have been used as reinforcing materials (fillers) for the rubber industry for many decades. Their presence in rubber is essential to achieve longer-wearing products, increased material strength and longevity, and for silica, decreased carbon emission.

Physical and chemical properties of these fillers play a vital role in terms of processing behaviour, as well as end product properties. Ash content, particle size distribution, pellet strength, surface area, Iodine adsorption number, pH, tint strength, quantitative structure analysis by oil adsorption number, oil adsorption after crushing under high load, toluene discoloration, silica content and many more physical and chemical properties govern the usage and effect of these fillers. At our facility we do wholesome analysis of fillers and go beyond that.

We offer complete testing, analysis, and problem solving for natural and synthetic rubbers under a single roof.
