PTM gets asked this one a lot: if SBR gaskets cost less than natural rubber gaskets, why not buy SBR every time? Sometimes you should. Other times it's a false economy, and the difference comes down to a few properties you can check in a minute. Strip away the price,...

Not all Gylon is the same, and picking the wrong style is a common mistake for buyers who assume it's a single product rather than a family of materials with genuinely different chemical profiles. PTM stocks and converts a wide range of Gylon styles, and here's a...

Our team here at PTM still sometimes gets calls from a customer who's found an old asbestos gasket sitting in a piece of machinery that's been running for decades, and they're not sure what to do about it. If that sounds familiar, you're not alone, and the good news...

Our team has watched materials come and go across five decades of gasket manufacturing, but few have solved as many problems as Thermiculite. Most engineers already know non asbestos gaskets as the standard replacement for old asbestos-based sealing, and Thermiculite...

Our team here at PTM still cuts a steady volume of cork gaskets every month, which might surprise anyone assuming synthetic rubber sheet has replaced cork everywhere. It hasn't. Cork remains one of the most specified sealing materials in automotive and industrial...

For much of the 20th century, asbestos was the go-to material for demanding gasket applications. It handled high temperatures, it was cheap, and it was widely available. The problem, as we now know, was the serious and well-documented health risks it carried. Asbestos...

Most sealing materials have a comfortable operating range. Push beyond it, and performance drops off fast. For applications involving sustained high heat, whether that's industrial ovens, furnaces, exhaust systems or high-temperature pipework, standard rubber or fibre...
