PPMA (polymethyl methacrylate) dosage

The analysis of polymethyl methacrylate (PMMA) allows for the identification and quantification of this thermoplastic polymer, widely used in coatings, packaging, cosmetics, and technical materials .
PMMA is known for its transparency, chemical resistance, and thermal stability . However, its analytical control is crucial to ensure formulation conformity , assess polymer purity , and detect any residual impurities from the polymerization process.

Analytical methods

chromatography and spectroscopy techniques to identify monomers and additives:

• GC-MS (gas chromatography coupled with mass spectrometry) : detection of residual methyl methacrylate and organic solvents,
• FTIR (Fourier Transform Infrared Spectroscopy) : structural identification of the polymer and verification of material conformity.
• Gravimetry : measurement of dry extract rate and control of pure polymer content.

These analyses can be carried out in accordance with ISO 11357 , ASTM D3418 or ISO 10993 (biological evaluation of materials in contact with the skin).

Industrial applications

The dosage of PPMA is essential in many sectors:

• Polymer and plastics industry : control of the composition of films, resins and varnishes.
• Cosmetics : verification of the conformity of nail polishes, gels or hair styling products containing polymethacrylate.
• Food packaging and contact materials : detection of monomer residues (methyl methacrylate) in accordance with Regulation (EU) No 10/2011 .
• Formulation and research : characterization of copolymers, plasticizers and additives used in complex matrices.

Matrices analyzed

• Plastic films and technical sheets
• Varnishes and polymer coatings
• Cosmetics (nail polish, gels, lacquers)
• Resins and composite polymers
• Polymer powders and granules

Further analyses recommended

For a complete characterization of polymer materials , YesWeLab recommends:

• FTIR analysis : structural identification of polymers,
• Thermal analysis by DSC : study of the glass transition and melting of the material,
• TGA analysis : evaluation of thermal stability,
• Scanning electron microscopy (SEM) : observation of surface morphology,
• Tensile test : measurement of the mechanical properties of the polymer.
