Sil­i­cone flu­ids man­u­fac­tured from re­new­able raw ma­te­ri­als

Chemical Industry Digest - - Renewables -

The in­ter­na­tional in­spec­torate TüvSüd has re­cently cer­ti­fied the Wacker Group’s mass bal­ance method for trac­ing re­new­able raw ma­te­ri­als in sil­i­cone man­u­fac­ture. The man­u­fac­turer is the first com­pany in the world to pro­duce sil­i­cone flu­ids with­out the use of fos­sil re­sources.

With the cer­ti­fi­ca­tion, the com­pany has a rec­og­nized pro­ce­dure for track­ing the use of re­new­able raw ma­te­ri­als through­out the pro­duc­tion process as far as the end prod­uct. Cur­rently, the chem­i­cals pro­ducer also uses plant-based methanol in its pro­duc­tion pro­cesses. There­fore, the com­pany is able to mar­ket sil­i­cone flu­ids ex­clu­sively man­u­fac­tured with the help of biomethanol.

Sil­i­cone flu­ids pro­duced with biobased or petro­chem­i­cally based methanol are chem­i­cally iden­ti­cal. How­ever, biomethanol based sil­i­cones have a sig­nif­i­cantly more fa­vor­able car­bon bal­ance, since no fos­sil raw ma­te­ri­als are in­volved in the methanol man­u­fac­ture. Ac­cord­ing to Wacker’s cal­cu­la­tions, around 1.6 met­ric tons of car­bon diox­ide can be saved per met­ric ton of sil­i­cone fluid. Sil­i­cone pro­duc­tion re­quires not only methanol, but also sil­i­con, which is de­rived from quartz rock or sand. Sil­i­cone flu­ids from biomethanol are thus pro­duced en­tirely from min­eral- or plant­based raw ma­te­ri­als.
