Identification and deformulation

Ingredient identification and deformulation

Physico-chemical analyses can be used to determine numerous elements in the formulation of a polymer material:

  • Nature of basic polymers: elastomers (NR, NBR, FKM, etc.), thermoplastics (PP, PA, PTFE, etc.), thermosets (epoxy resin, polyurethanes, etc.)
  • Nature of plasticizers and additives (stabilizers, vulcanizing agents, fire retardants, foaming agents, etc.)
  • Nature of mineral fillers (silica, chalk, glass fibers, etc.)
  • Composition by weight (content of plasticizers, polymers, carbon black and mineral fillers)
  • Quantification of the residual antioxidant and accelerator concentrations after curing and assessment of the depletion during the lifetime of elastomer components in use
  • Measuring the quantity of free sulfur in elastomer components
