Haydale Technologies Inc. is a wholly owned subsidiary of Haydale Graphene Industries, plc, based in Wales, UK.  HTI is the North American arm of Haydale worldwide.  The US company had its beginnings in 1976.  The company was created as a joint venture of Exxon Enterprises and Hulco, Inc. of Salt Lake City, Utah.  The company at that time was named Silag, Inc.  During this period, new methods of synthesizing silicon carbide were developed at a number of Universities.  The company licensed these technologies and launched the business.

In 1979 the company moved to Greer, South Carolina, and in 1981 the company became a wholly owned subsidiary of Exxon Enterprises’ Materials Division.  Exxon advanced the technology and synthesis techniques.  Then in 1982, Atlantic Richfield Company purchased the company. In 1984 the company became part of ARCO Chemical Company.

ARCO divested many of its non-oil assets in 1986-1987.  In December 1986, the company became incorporated as Advanced Composite Materials Corporation (ACMC).  In July 1987 Tateho Chemical Industries Company, Ltd. of Japan (TCI) purchased ACMC as a wholly owned subsidiary.

TCI owned and operated the company for 19 years. In 2006, TCI decided to divest.  Through a management buyout in conjunction with the investment community, the company became a standalone, privately-held entity in 2006, and its name was changed to Advanced Composite Materials, LLC (ACM, LLC).

In 2016, Haydale acquired all of the shares of ACM and formed Haydale Ceramic Technologies LLC.




HTI treats all customer requests as confidential.  Even if there is no confidentiality agreement in place, HTI operates with the principle that all requests, all projects, and all communication should be kept in confidence.  We operate internally on a need-to-know basis, and will even erect internal walls within the company to ensure your information remains confidential.  We have been involved in many highly confidential projects and know what it takes to operate in a trustworthy fashion.




Everything needed to survive and live well depends on our natural environment.  Sustainability has been defined as “the long-term maintenance of well-being, which has environmental, economic, and social dimensions, and encompasses the concept of stewardship, the responsible management of resource use.”  Sustainability assures we have and will continue to have water, materials, and resources to protect human health and the environment.

HTI utilizes raw materials that come either directly or indirectly from the earth.  Recyclable, agricultural materials are used to produce our Silar® Silicon Carbide Whiskers.  Other mineral-based hard materials are used to produce our ceramic powders and products.  At HTI, we think green, and our products reflect that very color.

Taking what was once in the earth and converting it to another useful product is done every day at HTI.  Great care is taken in our processes to conserve natural resources.  Water is recycled to cool equipment, and power consumption is constantly reviewed and optimized.  Efforts are constantly made to reduce our carbon footprint, and industrial wastes are kept to a minimum.
