Macor is a machinable glass ceramic material that posses outstanding engineering properties. Unlike other ceramics, Macor can be machined with ordinary metalworking tools. Macor is also a problem solving material combining the performance of a technical ceramic with the versatility of a high performance plastic. Macor has no porosity and when properly baked out, will not outgas. It is strong and rigid and, unlike high temperature plastics, will not creep or deform. Macor is also radiation resistant.

Features and Benefits:

Ultra High Temperature Performance (800 C continuous - 1,000 C peak). Low Thermal Conductivity.

Excellent Insulator. No porosity. Will not outgas. Professional Plastics stocks a large inventory of Macor shapes used primarliy in the semiconductor probe test industry. We also supply Macor to various industries requiring high-purity, high-strength and high temperature resistance. Worldwide shipping. E-Commerce Website.
