Greene Tweed & Co Benelux BV
Canadaweg 2A
HALSTEREN
NL-4661 PZ Netherlands
NL
[t] +31 164 612 123
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.
