Part design simulations for silicone rubber components

RubberWorld 3868 Views ,  , 

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.

Seals prevent bearing damage in EVs

RubberWorld 3976 Views , 

Freudenberg Sealing Technologies’ new generation electrically conductive seals prevent bearing damage caused by electrically induced corrosion, and also increase electromagnetic compatibility. Electric cars with drive systems that operate at 800 volts instead of the usual 400 can recharge in just 15 minutes, and produce enough power to drive several hundred kilometers. The power semiconductors in the inverter ensure that the direct current stored in the battery is converted into the alternating current required by the electric motor while driving. These power electronics are often positioned directly above the electric motor, and are also known as electric engine injection systems.

An overview of the silicone recycling process

RubberWorld 7543 Views ,  ,  , 

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

RubberWorld 4178 Views ,  ,  ,  , 

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

RubberWorld 1772 Views

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.

Total Cray Valley industrializes sustainably sourced Krasol diols

RubberWorld 4111 Views ,  , 

Total Cray Valley is expanding its hydroxyl-terminated diene resin portfolio with the industrial introduction of sustainably sourced farnesene-based resins, Krasol F3000 and Krasol F3100. The Krasol product line is known in the market as a source of well-defined hydroxyl-terminated liquid poly(butadiene) diol and monol grades. These materials are used in a variety of end-use applications as components in urethane, epoxy and UV-cured adhesive and sealant formulations for the automotive and electronic markets. The diene backbone incorporates hydrophobic quality and chemical resistance, as well as elastomeric softness and low-temperature performance.
