Simrit Introduces New Fluorocarbon Compounds for Demanding Semiconductor Sealing |
Jul 1013 |
PLYMOUTH, Mich., July 13, 2010 – As the fast-paced semiconductor industry continually develops the latest microelectronics innovations, smaller components – such as seals – are an often overlooked, but extremely critical, part of the process. To help its customers create the latest industry advancements, Simrit is debuting two new fluorocarbon (FKM) compounds – VO628 and VO793 – during SEMICON® West 2010 held July 13 to 15 in San Francisco.
With their high-purity and low metal ion impurities, both critical to ensuring that no contaminants go into the clean-room production of semiconductor wafers and chips, Simrit’s VO628 and VO793 materials were created specifically for use in semiconductor fabrication processes. Both materials can be utilized in a variety of products including O-rings and bonded gates.
“As a materials specialist, it is our job to ensure industry innovations are possible by developing compounds that can withstand the evolving chemicals, temperatures and materials that threaten traditional semiconductor applications,” said Robert W. Keller, materials development manager, Simrit Division of Freudenberg-NOK. “Our latest material developments, VO628 and VO793, offer superior purity while still providing the extreme performance requirements the semiconductor industry demands.”
VO628 is a 65 nominal Shore A hardness FKM compound, while VO793 is a 75 nominal Shore A hardness FKM compound. Both materials are brown and made with no fillers and minimal metal ion impurities to offer superior high-temperature and long-term compression set characteristics compared to traditional FKM materials.
Offering excellent resistance to oxygen etch and oxygen plasma systems and performance in rapid pump-down high vacuum systems, VO628 and VO793 are useful in semiconductor applications requiring rapid development of high vacuum levels.
The Simrit Division is based at Freudenberg-NOK’s headquarters in Plymouth, Mich. Freudenberg-NOK is part of the Freudenberg and NOK Group Companies, which have total annual sales of more than $7 billion. The global Freudenberg and NOK Group offers an extensive portfolio of precision-molded products for the aerospace, appliance, automotive, marine, medical, off-highway equipment, recreational vehicle and renewable energy markets.

“Engineered Seals Withstand Extreme Conditions,” as featured in Machine Design |
Feb 1019 |
Click here to view the article on Simrit’s sealing solutions for extreme conditions that Machine Design recently featured on their website and in their printed magazine.
Quote taken from the article:
Key points:
• Aerospace applications may call for seals that are fireproof, resist fluids, and work over a large temperature range.
• Viscoelastic properties help elastomeric seals work in subfreezing temperatures.
• Semiconductor and alternative energy applications require low-maintenance seals that resist chemicals and weather.

Simrit to Unveil Simriz® 508 Compound at SEMICON West 2008 |
Jul 0810 |
SAN FRANCISCO, July 15, 2008 – To specifically address the evolving needs of the semiconductor industry, Simrit – the industrial sealing products division of Freudenberg-NOK – will debut its Simriz® 508 material during SEMICON West 2008. Simrit’s new material was specifically developed for demanding, high-temperature static and dynamic sealing applications in dry chemical environments.
Simriz 508 is a white perfluoroelastomer (FFKM) material that has a service temperature range of negative six to 300 degrees Celsius and exhibits excellent plasma resistance and minimum particulation in a wide-range of plasma environments. The O-ring is a cost-effective sealing solution that offers very low trace element contamination in both wet and plasma applications.
Ideal for a variety of dry processes, including deposition, oxide and metal plasma etching, ashing, metallization, ion implant and others, the Simriz 508 material is appropriate for the following equipment locations: chamber lid seals; bell jar seals; endpoint windows; gas inlet seals; isolator valve seals; KF fittings; slit valve seals; valve seals; and window seals. Designed for thermal stability and nearly universal protection against chemical attack, Simrit’s proprietary family of Simriz FFKM compounds offers premier sealing performance. All of the Simriz compounds approach PTFE (polytetrafluoroethylene) chemical resistance and have excellent plasma resistance for dry processing. Simrit is the single-source developer of Simriz, starting with the base polymer, thus ensuring complete oversight and continuity in the compounding process, and eliminating any need for costly outsourcing.
For more information or to speak with a Simrit representative about the Simriz 508 material, visit the Simrit booth (#N6289) during SEMICON West 2008 held here from July 15 to 17.
The Simrit Division is based at Freudenberg-NOK’s headquarters in Plymouth, Mich. and is part of the Freudenberg and NOK Group, which has total annual sales of more than $12 billion. Simrit offers an extensive portfolio of sealing solutions for the aerospace, appliance, diesel engine, industrial, marine, off-highway equipment, oil and gas, recreational vehicle and semiconductor markets.

Simrit Publishes New Plate Seals Brochure |
Oct 0716 |
Plymouth, Mich., Oct. 16, 2007 – To ensure that its customers are receiving the most accurate and current product information, Simrit – the industrial sealing products division of Freudenberg-NOK – recently published a new Plate Seals brochure. For a copy of this brochure, visit the Simrit website www.simritna.com and use the Literature Request Form on the “Brochures” page. You can also download a PDF file of the brochure from this page.
The Simrit Plate Seals brochure provides detailed descriptions of plate seals, which are hybrid seals designed to incorporate the best features of flat gaskets and O-rings, while eliminating the drawbacks associated with each of those sealing methods. For instance, the brochure highlights groove-bonded and edge-bonded plate seals, Simrit’s proprietary materials for plate seals, and plate seals specifically used in semiconductor and aerospace applications.
Furthermore, the brochure emphasizes the advantages of using plate seals:
• Ease of installation
o Rigid seals are easy to handle and install
o Offers visual confirmation of seal installation
o Seal is chemically and mechanically bonded to mating surface and can not be dislocated
o Requires less sealing force than flat gaskets
• Cost Advantage
o Reduces expensive machining required on mating components
o Single plate/multi-port sealing capabilities reduce inventory and minimize warranty costs due to missing or poorly installed sealing elements
o Allows high pressure sealing without requiring backup rings
• Performance
o Controlled squeeze metal-to-metal contact prevents over-compression, which is known to cause premature seal degradation
o Plate seals have the potential of reducing elastomer exposure and lessening fluid/swell issues
The Simrit Division is based at Freudenberg-NOK’s headquarters in Plymouth, Mich. Freudenberg-NOK is part of the Freudenberg and NOK Group Companies, which have total annual sales of more than $12 billion.
