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

techniques chromatography and spectroscopy 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.
