Products Introduction
Dodecenyl Succinic Anhydride/Tetrapropylene Succinic Anhydride K12 (DDSA, TPSA) It is a series of alkenyl succinic anhydride products of Vertellus, which are different products synthesized by the reaction of maleic anhydride and a variety of olefins, including: linear octenyl succinic anhydride (OSA), starch-grade linear Octenyl succinic anhydride, nonenyl succinic anhydride (NSA), linear dodecenyl succinic anhydride (N-DDSA), branched chain dodecenyl succinic anhydride (TPSA).

Purpose
Dodecenyl Succinic Anhydride/Tetrapropylene Succinic Anhydride K12 (DDSA, TPSA) As an epoxy curing agent, it can improve the waterproofness and toughness of epoxy resin. Ventruus high-purity dodecenyl succinic anhydride is widely used in the sealing and packaging of electronic components. As a cross-linked epoxy curing agent, it can improve the performance of the product in many ways compared with other materials: improve Combines strength, increases toughness, improves electrical resistance and extends seal life.

In the application of corrosion inhibitor, alkenyl succinic anhydride and alkenyl succinic anhydride obtained by hydrolysis Succinic acid (including derivatives of both) is often used as a corrosion inhibitor in water and hydrocarbon media. After dodecenyl succinic anhydride/tetrapolypropylene succinic anhydride K12 (DDSA, TPSA) is added to gasoline and diesel, water can be absorbed by the hydrolysis of the anhydride, and the acid produced becomes a corrosion inhibitor in it. Adding a small amount of dodecenyl succinic anhydride to mineral lubricating oil can prevent pitting corrosion and green scale formation on lead watch copper bearings. At the same time, dodecenyl succinic anhydride can also improve the lubricity of the oil, increase the breakdown temperature, and reduce the friction system.
