PS-SEAL® Non-Standard lip materials

Garlock PS-SEAL® Non-Standard lip materials for dynamic applications For a number of years, Garlock’s Fluoroelastomer (FKM/FPM) PS-SEAL® Standard with a GYLON® Black lip is known for its industry-leading reliability when sealing critical applications. However, when the sealing requirement requires an alternative solution to an FKM, Garlock also created the PS-SEAL® Non-Standard. Generally, the Garlock PS-SEAL® Non-Standard seal can be easily […]

Thermal Process

Semiconductor Manufacturing – Thermal Process The term ‘thermal process’ covers a broad scope of installations. These installation temperatures are usually higher than Plasma Processes and can go up to +300°C. In addition, thermal-based installations require not only sealing materials with a particular chemical resistance demands but also ones with good mechanical features and low compression set. Thermal Processes include: Atomic […]

Plasma Process

Semiconductor Manufacturing – Plasma Process The plasma process is one of the most hostile for elastomers, especially those vulnerable to chemicals and/or close to the substrate or the wafer. The most hostile plasma processes for elastomers include oxygen resist strip and radical based plasmas (such as remote NF3) and chamber cleans using remote plasma sources (RPS). Every seal, especially one […]

Semiconductor Material Grades

Semiconductor Material Grades

Material Grades used in Semiconductor Manufacturing What are the Semiconductor Material Grades? Performance requirements vary based on elastomer location in the process. The advantages of using our elastomer materials include decreased cost of ownership, extended tool Preventative Maintenance (PM) cycles, lower process defects, decreased particle origination and maximised device performance. Below is the table with our recommended material grades (Other […]

What is the difference between Teflon and PTFE?

Teflon vs PTFE

Teflon™ vs PTFE The sealing industry is full of trade names, technical phrases, and acronyms, which makes it hard to know what is what. In this learning journal, we will explain what Teflon™ and PTFE are, and also the differences. PTFE – what is it? PTFE is a carbon and fluorine synthetic polymer – Polytetrafluoroethylene. It is obtained from Tetrafluoroethylene […]
