Silicone and epoxy hybrid resins exhibit wide range of mechanical properties

The largest range of silicone and epoxy hybrid resins for the 3D printing of wearable devices, biomedical equipment and soft robotics has been developed by researchers from the Singapore University of Technology and Design (SUTD). In a study published in Applied Materials Today, the range of tunable functionally graded materials, which displayed over five orders of magnitude of elastic modulus, demonstrated excellent interfacial toughness, higher precision in complex structures and better fabrication control for the integration of mechatronic components.

Part design simulations for silicone rubber components

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.

An overview of the silicone recycling process

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.

Effects of aerosil on the properties of silicone rubber

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

Construction silicone market in the Americas forecast at $1.2 billion by 2025

America’s construction silicones market size is forecast to reach around $1.2 billion by 2025, after growing at a CAGR of 6 percent during 2020-2025. Silicones are polymers composed of many repeated subunits of siloxane. An increase in the standard of living has increased the construction activities in America, which in turn boosted the use of silicone for adhesives and tapes. Silicone rubbers are also used as a sealant in windows and doors to insulate the building from heat and moisture. Moreover, rising environmental concerns and the presence of substitutes such as urethane based sealants and polysulfide sealants act as a restraining factor for the growth of America’s construction silicones market.

Wacker will manufacture upstream products for building protection agents and binders at its Nünchritz site

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.
