CHEMICAL ANALYSIS OF RUBBER COMPOUNDS AND VULCANIZATES (VULCANIZED RUBBER) COMPOSITIONS

• Identification of rubbers or/and other polymers
• Quantitative determination of individual rubbers
• Determination of total organic additive content (extractive matter)
• Qualitative and semi-quantitative determination of individual organic additives (softeners, antidegradants, crosslinking agents, processing agents, etc.)
• Determination of carbon black content
• Qualitative and quantitative determination of inorganic components
• Determination of zinc, calcium, magnesium, silicon, aluminium and titanium content
• Determination of total sulphur content
• Determination of chlorine, bromine and fluorine content
• Determination of nitrogen content

Ascertainment of vulcanized rubber quality and properties by chemical methods

• Identification of surface substances (migrating components)
• Identification of impurities and inhomogeneities
• Estimation of crosslinking degree by determination of unbound sulphur, reaction enthalpy and equilibrium swelling in solvents
• Calorimetric and spectroscopic monitoring of crosslinking course
• Testing of resistance to various media by single-sided and immersion swelling
• Testing of certain products for suitability in medical and food use
• Determination of volatile components in vulcanized rubber (Fogging)
