Graphite and Oxidation

A recurring issue we hear about from people using graphite components is graphite oxidation. This term describes unwanted redox reactions where oxidizing agents modify graphite properties negatively. Hence, especially at high temperatures, steps need to be taken to eliminate oxygen presence so that oxidation and deterioration of graphite components is avoided. Semco strives to educate our clients who order custom graphite components about the proper environments in which those components should operate. However, new clients will come to us expressing their frustration that graphite components are failing long before they should. One reason to work with the synthetic graphite experts...

Graphite Cement: A High Temperature-Resistant Building Material

Graphite cement typically refers to a material with adhesive and bonding physical properties that contains graphite as one of its primary components. This is not your typical cement, one of the most ubiquitous, and necessary, building materials used by people today. Your typical cement is made of forms of lime, silica, iron, and aluminum. Like manufactured graphite, cement’s formula can be adjusted to suit specific purposes. One of those materials that can be added to cement to give it certain properties is graphite. Graphite is a form of carbon known for its excellent electrical conductivity, lubricating properties, and high temperature...

Teflon: Not Just for Non-Stick Cookware

Graphite is a high temperature-resistant material. It isn’t too surprising then to find that graphite and Teflon have been combined in industrial applications that go beyond just non-stick cookware, like gasket material (and many others). Teflon-coated graphite refers to a material that consists of a layer of Teflon (a brand name for polytetrafluoroethylene, or PTFE) applied to the surface of graphite. This combination offers unique properties and applications, primarily due to the characteristics of both materials. Between the high thermal conductivity and electrical conductivity of graphite to the chemical resistance and low friction of both materials, Teflon-coated graphite makes a...

International Organization for Standardization 9001 Certification

Semco Carbon is proud to be an ISO 9001-2015 certified company. The decision 4 years ago to prepare, apply, and become certified was driven by our belief that we were already operating at a high standard that the certification would indeed confirm. We also knew that working towards and achieving this certification would contribute to the success of our company in many ways, from strengthening supplier relationships to improving the morale at our manufacturing facility in Lorain, OH. It was no small decision to apply for this certification, and it took hard work and collaboration by and across all departments...

The Carbon Material Par Excellence, Synthetic Graphite

Among carbon materials, synthetic graphite is one of the most fascinating and has found its place in a wide range of industries due to its unique properties. At Semco, we work with various forms of graphite, but synthetic graphite stands out as a highly valuable and versatile variant. With its exceptional electrical conductivity, thermal stability, and mechanical strength, synthetic graphite has become a game-changer in advanced industries. We’re taking a step back here from the details of machining graphite components in order to explore the remarkable properties and applications of this unique carbon material. We’ll also try to shed light...
