Mineral and Glass Filled Novolak Molding Compounds, Encapsulation Epoxy is a subcategory of Epoxy. The additative is added during the manufacturing process. Its flexural modulus ranges from 1400 to 2400 MPa. Its tensile strength ranges from 5000 to 12500 MPa at break. Its flexural strength ranges from 10000 to 21800 MPa. Its compressive strength ranges from 24000 to 48000 MPa. Its Izod Impact strength ranges from 0.3 to 0.5 J/cm. Its specific gravity ranges from 1.6 to 2.05. Its coefficient of thermal expansion ranges from 18 to 43 x 10^-6/°C. Its melting temperature ranges from 145 to 155 °C. Its molding pressure ranges from 0.25 to 3 MPa.

Epoxy is a thermoset polyadduct. Common trade names include Acme, Aerolam, Basoset, Beckopx, Conapoxy, Corlar, Cycom, DER, Desmobond, Dobeckot, Dynopon, Ecco, Epikote, Epocast, Epodite, Eprosin, Eurepox, Exatron, Grilonit, Hysol, Isochembond, Lekutherm, Lopox, Nikalet, Paraplex, Quartrex, Scotchcast, and Synthane. Epoxy possesses many useful properties: air curable, highly fillable, low shrinkage, low susceptibility to stress formation, good adhesion to almost all materials, high tensile and vibrational strength, high heat resistance, high heat deformation resistance, high chemical attack resistance, good aging properties, good electrical and dielectrical properties, odorless, tasteless, and low flammability. Epoxy is commonly used in adhesives and reactive molding compounds. Epoxy is a copolymer, which means it is formed from two different chemicals, usually referred to as the "resin" and the "hardener". Epoxy-based materials can be used for coatings, adhesives, composite materials, mold making, and electrical insulators. When working with epoxy, vinegar is an effective and safe solvent for cleaning epoxy resins from tools, brushes, skin, and most surfaces.
