22 May 2006 - Greene Tweed & Co Benelux BV
| In response to growing customer demand for a softer high-performance seal, Greene, Tweed announces Chemraz 656, an advanced perfluoroelastomer offering unsurpassed resistance to the harsh chemicals common in today's semiconductor processes. With its low-metallic-ion content (<5355 ppb), Chemraz 656 provides a high-purity seal that virtually eliminates the risk of contamination. |
In response to growing customer demand for a softer high-performance seal, Greene, Tweed announces Chemraz 656, an advanced perfluoroelastomer offering unsurpassed resistance to the harsh chemicals common in today's semiconductor processes. With its low-metallic-ion content (<5355 ppb), Chemraz 656 provides a high-purity seal that virtually eliminates the risk of contamination. The 70 durometer (Shore A) material was developed to meet the evolving needs of the semiconductor industry for increased reliability in harsher processing environments. "Chemraz 656 is the perfect choice for applications having low sealing forces and low tolerance stackups, including bonded slit valve gates, chamber and window seals, gas inlet seals, and lid seals," said Phil Paino, president of Greene, Tweed and head of its semiconductor business. Offering stable operation at service temperatures up to 450°F (232°C), Chemraz 656 is compatible with most semiconductor processes, including chemical vapor deposition, dry plasma etching, rapid thermal processing, and diffusion. Greene, Tweed leverages expertise in a variety of markets and products to give customers the most innovative solutions to meet performance challenges and reduce total cost of operation. With fully qualified engineering, sales and support personnel located throughout the Americas, Europe and Asia, Greene, Tweed delivers solutions to individual customer applications on a global scope. Greene, Tweed products are sold and distributed worldwide. For additional information, contact Greene, Tweed at +1.215.256.9521.

About: Greene Tweed & Co Benelux BV
Greene, Tweed specialises in the development, manufacture and supply of rings, seals and profiles for industrial applications in which extremely high specifications are set for the material; brand names include Chemraz, WR and AR. An early product in the portfolio, the G-T Ring, was introduced and approved for use in the landing gear of the F-4 Phantom in 1964. The G-T Ring remains a core product in Aerospace landing gear today. As the business developed, strategy warranted the establishment of corporate headquarters in Kulpsville, Pa., USA. in the 1970s. With this foothold, the company expanded around the globe. In the early 1980s it introduced several versatile elastomers, such as Fluoraz, and designed pioneering product geometries, such as the first "capped seal." Arlon, a tough, high-temperature, semi-crystalline engineering polymer, also joined the product line, followed shortly by one of Greene, Tweed's most innovative products, Chemraz, a chemical-resistant elastomer, effective in the most extreme temperatures. Recognizing the race toward a global economy, Greene, Tweed began geographic expansion by opening offices in Germany, England and France. By the mid 1980s, Greene, Tweed had established a presence in the Pacific with a Japanese office. The Asian market has maintained its pattern of growth with additional offices today in Singapore and Korea. The turn of the century ushered in a new product, Orthtek, a lightweight, thermoplastic composite with high-strength and radiolucent properties, that satisfies the demands of the Medical and Biotechnology industry. Worldwide expansion has continued with new offices in the Netherlands, Italy and Spain. A tradition of creative and innovative ideas has also grown with the development of new products, from new composite technologies and vision systems to fibre optic connectors and extreme electrical connectors. Greene Tweed’s WR and AR product ranges are distributed by Flowserve all over Europe. In Belgium the Greene Tweed & Co products are also distributed by Humitab BVBA in St.Job in ‘t Goor.
