TESTING AND ANALYSES OF ORGANIC ADDITIVES

Mineral and synthetic oils

• Identification and chemical characterization
• Determination of paraffinic, naphtenic and aromatic hydrocarbons content in mineral oils
• Determination of viscosity (dynamic and kinematic)
• Determination of refractive index and density
• Determination of flash point (in open and closed cup)
• Determination of acid or base number and saponification number
• Determination of iodine number
• Determination of chlorine and sulphur content
• Determination of water content
• Determination of volatility

Antidegradants, crosslinking agents, processing additives

• Identification
• Detection of impurities
• Determination of melting point and melting enthalpy
• Determination of softening point of resins
• Determination of acid number, saponification number and hydroxylic number of some resins
• Determination of nitrogen, sulphur and chlorine content
• Determination of carrier content

Solvents

• Identification
• Qualitative and semi-quantitative determination of solvent mixture components
• Determination of refractive index
• Determination of water content
• Determination of non-volatile impurities
