Read MorePlasma 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 […]
Read MoreSemiconductor 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 […]
Read MoreGuide to Seal Installation
Expert advice on seal installation The first step to having an efficient and lasting part is getting a precise, custom manufactured seal for your application. Anyhow, errors happen during installation of the seal, which leads to failure, no matter what the quality of the seal was in the first place. Make sure the seal and assembly equipment are clean Cleanliness […]
Read MoreInternational O Ring Sizes
O Ring Sizes An O Ring (also known as Toroidal Seal) is the most popular seal used globally nowadays. It is utilised to mould a physical barrier to stop the blending of liquid fluids or gasses. The O Ring’s straightforward toroidal configuration has proven to provide high sealing effectiveness over a broad scope of installations. We distribute, stock and manufacture […]
Read MoreConversion Formulas in Sealing
Below Formulas can be used to convert your required metrics. Cross Section CS = (OD – ID) ÷ 2 Inner Diameter ID = OD – (2 x CS) Outer Diameter OD = ID + (2 x CS) Inner Diameter ID = (CL ÷ π) – CS °F = (1.8 x °C) + 32 °C = (°F – 32) ÷ 1.8 […]
Read MoreWhat is Rubber Shrinkage?
What you need to know about Rubber Shrinkage The calculation of O Ring squeeze is one of the main elements to take into consideration when designing a seal for a particular application. This is because the amount of O Ring by the media can have an impact on the design, material selection, and other important features. O Ring Squeeze – […]
Read MoreTypes of Silicone
Types of Silicone: MQ, VMQ, PMQ & FVMQ – what does it all mean? Silicone is used in a wide selection of industries, including Food & Drink, Pharmaceutical to Aerospace. It presents low toxicity, excellent flexibility, resistance to oxygen, UV, ozone and microbial growth. Silicone as a sealing material has one of the greatest scopes of working temperatures. A Standard […]
Read MoreWhat is the difference between Teflon and 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 […]
Read MoreProfile Seal DIN3869 Advantages & Features
Everything you need to know about Profile Seals DIN3869 Axially static soft seals combined with threaded elements are generally called Profile Seals (DIN3869 Seals or Fluid Connector Seals). They are often used as an alternative to an O Ring/Back-up Ring combination. How do they provide effective sealing? Profile Ring’s purpose is to stop the medium from leakage, at the same […]
