Raw Material

At Centro Tecnológico Riojano, we apply a comprehensive control to all the components that end up as part of rubber and lubricant mixtures.

Tests on RAW MATERIAL:

  • Quantitative determination by means of Thermogravimetric analysis
  • Determination of the glass transmission temperature (Tg) of materials
  • Determination of purity of materials by melting point (DTA/ DSC)
  • Determination of thermal phenomena in materials (DSC)
  • Ash content
  • Identification of nature and components by means of Infrared spectroscopy
  • Viscosity in rubber using the Mooney method
  • Determination of dynamic rheological and mechanical properties (RPA - Rubber Process Analyzer)
  • Density of solids and liquids
  • Determination of extractable components in solvents
  • Determination of gel content in rubber
  • Fine content of carbon blacks
  • Determination of volatile material in carbon blacks and white fillers
  • Bulk density of carbon blacks and white fillers
  • Assessment of dispersion in rubber
  • Assessment of properties in rubber of black carbons and white fillers
  • Determination of sieve residue
  • Determination of ethylene content in EPDM polymers
  • Determination of acrylonitrile content in NBR polymers
  • Determination of kinematic viscosity
  • Determination of viscosity index
  • Determination of open cup flash point
  • Determination of refractive index
  • Determination of hydrocarbon chain
  • pH determination
