Methylpyrrolidine, also known as 2-Methyl-2-pyrrolidone, is an organic compound commonly used as a solvent, paint thinner, and in chemical manufacturing. It is widely used in the production of polyurethane foam, textiles, and paint. Common applications in the electronics industry include cleaning and etching of printed circuit boards.
When rubber is exposed to methylpyrrolidine, it can be degraded through a variety of mechanisms such as oxidation, swelling, embrittlement, and cracking. Oxidation can occur when the rubber is exposed to oxygen in the presence of the solvent, leading to discoloration, cracking and failure. Swelling can occur when the rubber absorbs the solvent and increases in volume, potentially leading to cracking and failure. Embrittlement can occur when the rubber is exposed to higher concentrations of the solvent, which can reduce the elasticity of the material and lead to failure. Finally, cracking can occur when the rubber is exposed to thermal cycling or mechanical stress.
