Poly(ethyl methacrylate)

Poly(ethyl methacrylate) (PEMA) is a hydrophobic synthetic acrylate polymer. It has properties similar to the more common PMMA, however it produces less heat during polymerization, has a lower modulus of elasticity and an overall softer texture.[7][8] It may be vulcanized using lead oxide as a catalyst[9] and it can be softened using ethanol.[7]

It is used as an impression material of ear canals for fabrication of hearing aids.[10][11] It is also used in dentistry as a chair-side denture reline material for partial and complete dentures [12] as well as a tissue conditioner with implant supported dentures.[13] It is used as a component of fossil coating and preservation [14] and for fabricating artificial nails [15]
