FRP materials are flexible ones and can be used by FRP tanks manufacturers to intend robust silos and storage tanks for industrial client. Each material carries its unique properties and in this post, we will discuss about resins that manufacturers use for producing FRP tanks and products and making them robust and non corrosive.

Isophthalic Polyester Resin

Isphthalic polyester resin belongs to a broad class of resins formulated from isphthalic acid, maleic anhydride and glycols. The certain resin specification is picked by manufacturing unit engineers to impart desired properties and corrosion resistance. These Isophthalic polyester resin is used for moderate corrosion resistance applications that would be used at temperature range around 180 degrees Fahrenheit.

Properties of Isophthalic polyester resin-

Water resistant
Acid resistant
Weak bases resistant
Hydrocarbons resistant like oil and gasoline

Vinyl Ester resin

Vinyl ester resin are polyester resins, however they are usually categorized in separate list from polyesters as they have enhanced mechanical properties and corrosion resistance. Vinyl esters provide enhanced strength and better impact and thermal shock resistance as compared to polyester resins. These resins offer superb resistance to alkalis, acids, hypochlorites, and other solvents.

Bisphenol A Fumarate polyester resin

This resin is prepared from a process in which experts perform reaction between bisphenol A and propylene oxide and fumaric acid. By this reacting phase, resin achieves a resistance against alkali environments. This type of resin is usally used for applications involving hot caustic solutions. It is ideal for service with acids, salt solutions and selected organic solvents to a temperature range of about 250 degrees Fahrenheit.

Chlorendic polyester resin

It is unsaturated, halogenated polyester resin used for making equipments that is operating at elevated temperatures or in extremely oxidizing environments like hot, wet chlorine. These resins are usually suited for making chimney liners, chrome plating tanks, flue gas duct, pickling tanks, and chlorine headers.

Phenolic resins

These are earliest commercialized thermoset resins that was first appeared in the late 1800. There are two types of phenolic resins- resole and novolac. Resoles are base-catalyzed thermosetting resins that have self-crosslinking design. Novolacs are catalyzed with acids and require a hexamine crosslinker to transform into thermosetting. These resins provide high temperature resistance, chlorinated solvents resistance, salt water resistance, and excellent smoke/fire properties.

There are a lot more resins used by FRP tanks manufacturers India to construct distinct range of products for industrial customers.
