Epoxies are one of the most important and prominent thermoset polymers because of its specific features. Because of these features, epoxies find very important application areas in engineering. In here, we explain these properties and applications of epoxies and give informations about an epoxy material called epichlorohydrin.
What Are The Epoxies And Their Properties?
Epoxied are from the chemical group is called as epoxides which has formulation of epoxied-oxide. Curing of epoxides is very hard and specific curing agents must be added into epoxides. Important curing agents for epoxides are acid anhydrides and polyamines. And uncured epoxides has very low degree of polymerization. So cross-linked molecular structures must be obtained for good mechanical strength and rigidity. Heat and chemical resistance are also very important properties of cured epoxides. Some of applications of epoxides;
- They are used in glass-fiber reinforced composites as adhesive agents.
- Surface coating and industrial flooring applications of epoxies are also very important applications.
- Epoxies are also very good electrical insulators. So they are generally used in electronical applications as insulative elements.
What Are The Properties Of Epichlorohydrin Thermoset?
Epichlorohydrin has chemical structure of C3H5OCl and this material’s curing agent is generally triethylamine which has chemical representation of C6H5–CH2N–(CH3)2. Epichlorohydrin is a completely brittle material that has 0% of elongation value according to its original shape. The production method of epichlorohydrin is condensation polymerization method. Elasticity modulus of epichlorohydrin is around 7000 MPa and tensile strength of epichlorohydrin is around 70 MPa.
