Freudenberg’s new development for the vulcanization of chloroprene rubber eliminates the need for ethylene thiourea (ETU) as an accelerator – while still meeting the strict requirements of the automotive industry. With this innovation, the company follows its own sustainability goals and also sets a benchmark for new elastomer compounds.
Using ethylene thiourea (ETU) as an accelerator in the vulcanization of chloroprene rubber is standard in the industry. Products with this accelerator have been used successfully for decades and show very good values in terms of low-temperature flexibility as well as the required resistance to media such as greases and lubricants. Due to the risk of reproductive toxicity and its damaging effect on fruit, however, ethylene thiourea should no longer be used if its omission is technically and economically feasible. But so far there have been no alternatives that offer a similar performance or even met the requirements.
Die cutting is an all-inclusive term for the process of using a die to cut sheets or rolls of a variety of materials, such as foils, laminates, gasket materials, polyesters, polycarbonates, and more.
Leading manufacturer of reliable filter & distillation technology for pulp & paper, chemical and petrochemical, and semiconductor applications. Their membrane technology helps to reduce load on energy-consuming evaporators or distillers.
Customer experienced seal failure in the form of extrusion; the housing structure for their membrane filter could not adequately accommodate the OEM seal
In many countries, the expansion of renewable energy is an imperative. To ensure the energy transition’s success, it will be crucial to transport the electricity generated in hydroelectric plants and in solar and wind farms to consumers with minimal energy loss. New electric power lines are now expected to supplement those already in existence. After all, more energy from windy coastlines has to travel deep into the interior. Distribution stations and substations are part of these high-voltage networks. They connect overhead power lines, which transmit electricity at more than 110,000 volts, with local distribution networks that operate at low voltages. Substations can be designed more compactly with completely encapsulated, gas-insulated switchgear as opposed to those using ambient air. Accordingly, gas-insulated switchgears can be used in buildings in a space-saving manner, which is important in urban areas. When electric circuits are switched

This is the second part of a three-part series on silicone processing options for life science applications. In part one, we discussed the chemistries of silicone. This article concentrates on the methods and processing of medical silicones.
We’ll be discussing, at a high level, three different methods: profile extrusion, which is quite common to design products; compression molding; and injection molding.
There is multi-layer extrusion, co-extrusion, and a variety of different profiles. They can range from solid profiles to hollow profiles that are symmetric to non-axisymmetric. This is a smattering of the types of extrusion that one can find and design for use in life sciences.
There are variations on this term that we use very generally as extrusion

A diaphragm flapper part cut from a 4100-3NL Medical Bag which goes into a medical device, ultimately making contact with a stream of gas which flows into patient lungs
Customer was producing diaphragms internally with a small press but could not meet increased demand and required quality of the flapper part - no contaminants could be added during the cutting process

The ZAVA® Seal Ring is a split O-ring or V-ring with a patented Quick‑Lock solution that locks in minutes. Once the rubber ring is locked in place using the quick-connect coupling, it is impossible to separate.
The Quick-Lock consists of a sleeve and a pin which is locked by pushing the pin into the sleeve and pressing it together. It is made of acid-proof stainless steel (SS 2343).
ZAVA® Seal-Rings are manufactured in different lengths and cross sections and are available in NBR or AFLAS® materials.
Because so many applications are custom sizes, the

Excessive costs and extended lead times for critical OEM sterilizer gaskets hampered research efforts
Customer wanted to identify raw material and sterilizer gasket specifications for a direct replacement for 8 different gasket styles
After identifying the silicone material specifications, Gallagher Fluid Seals located an approved
Freudenberg Sealing Technologies' peroxidic-crosslinked fluoroelastomer material 75 FKM 239961 now also has received pharma-specific approval according to USP Chapter 87. The result of the in vitro conformity test confirms that the material has no toxic effects on cell cultures. With this advancement, bisphenol crosslinked FKM materials can be replaced in the food industry. The immediately available high-performance material is very resistant to media and temperature and is ultrapure.
FKM has become an integral material for the process industry. It is suitable for applications under high temperatures and with aggressive media. These properties are critically important for the food and beverage as well as in the pharmaceutical industries. Those beneficial properties lead to high demand for the material and this in turn to long delivery times. The material from Freudenberg Sealing Technologies meets high purity standards and
Gallagher Fluid Seals’ customer created the world’s first and most advanced 3D metal printing process that transcends the ability of traditional manufacturing. Their proprietary and patented printing technology welds metal powder layers to an area 10x faster than competitors.
Our customer was having issues with material waste on their
metal 3D printing machine due to insufficient sealing. As designed, the system would allow metal alloy debris to gather on the cylinder rod, rendering the material unusable. Due to time restraints, the new
