Industrial Aerosol

Mexichem is a leading supplier to technical propellant markets including industrial Klea Logoaerosols. Klea® propellants are used to deliver products by propelling from pressurised containers or to form foams within polymer or other matrix materials.

HFC propellants continue to play a vital role in a number of product delivery systems ranging from insecticide foggers through to emergency tyre inflators. Many of these important but often overlooked applications utilise Klea®134a for more specialised technical products including those where use of a flammable propellant would have unacceptable risks for the end-user.
