Key differences between epoxies and resins.
Difference between polyester and vinylester resin.
Epoxy is extremely strong and has great flexural strength.
Differences between resins there are three main types of resins used for composite materials.
Per square inch while a polyester resin can hold less than 500 lbs.
But there are several key differences between epoxies and resins.
Polyester vinyl ester and epoxy resins.
Vinyl ester resins are produced by the reaction esterification between an epoxy resin and an unsaturated monocarboxylic acid.
Polyester resins are standard resin for composite construction.
See all epoxy resin products.
Vinyl esters also use peroxides e g.
An epoxy s relative strength can hold up to 2 000 lbs.
Epoxy is known for its higher bonding capabilities overall.
Ortho polyester isothalic polyester and vinylester resins are compatible they all have styrene commonly known as the fiberglass smell and chemically bond to one another.
Because of their chemical structure vinyl esters and epoxies offer higher mechanical strength adhesion and heat resistance over polyester resins.
Our 300 21 and 400 21 epoxy resins have a flexural strength of 17 500 psi.
