Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).

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]
