The successful design of medical device components is increasingly dependent on simulations based on finite element analysis (FEA). Simulations provide a rapid and cost-effective way to determine optimal construction of multi-component systems, as well as information on how components interact with each other during use. Investing in accurate, early design simulations can provide significant resource savings by decreasing the amount of iterative loops necessary in the prototype process to validate the overall device design for FDA or other governing body approvals.

With global annual production of silicone expected to grow to 2.9 million tons by 2025, it is increasingly important to have an environmentally-friendly end-of-life option for silicone products. The current solution for discarding silicone scrap is to either landfill or incinerate it. Both of these are detrimental choices for the environment.

Silicones or polysiloxanes belong to a class of elastomers and are often referred to as silicone rubber. The prevailing type of polysiloxanes is polydimethylsiloxane (PDMS). Development began in 1940 when Eugene G. Rochow and Richard Müller independently developed the synthesis of methylchlorosilanes directly from elemental silicon. This discovery marked the beginning of a series of important findings on a new class of materials, namely silicone elastomers. The first silicone based product was a coating for the airplane industry, presented in 1942 by Dow. Presently, silicones are used in thousands of applications. Worldwide, the market for silicone consumption shows steady growth year after year

Wacker Group has started to build a liquid resins unit at its Nünchritz site. This unit will supply key upstream products for formulating silicone based building protection agents and binders for exterior paints and industrial coatings. At the moment, only Wacker’s Burghausen site produces these substances. Scheduled to go on stream at the end of 2022, the new unit will close important material loops and so further increase the cost-effectiveness of Wacker’s integrated production system. Capital spending amounts to some €30 million.
