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 has an overall softer texture. ^[7] It may be vulcanized using lead oxide as a catalyst ^[8] and it can be softened using ethanol.

It is used as an impression material of ear canals for the fabrication of hearing aids. ^{[9] [10]} It is also used in dentistry as a chair-side denture reline material for partial and complete dentures as well as a tissue conditioner with implant-supported dentures. It is used as a component of fossil coating and preservation ^[11] and for fabricating artificial nails ^[12]
