Rod Seals Explained, What is a Rod Seal?
A Beginner’s Guide To Rod Seals Rod Function: The rod, also known as the piston rod, plays a crucial role in hydraulic cylinders by converting hydraulic energy into linear mechanical movement. It absorbs hydraulic pressure from the piston, transmitting it to the object or load for movement. To ensure smooth movement and prevent metal-on-metal contact with the cylinder head, guide […]
Read MoreWhat is a BSE/TSE Certificate
TSE Certificates (Transmissible Spongiform Encephalopathy) come packaged with products that could potentially have TSE risk, such as BSA (Bovine Serum Albumin). Still, some people don’t know what the certificate means or why it is so important. If you’re shopping for bovine-derived reagents for your research, you’ve probably come across a mention of being ”TSE Compliant” quite a few times but wondered what […]

EnDura® Range Perfect For Extreme Conditions M Barnwell Services are one of the UK’s leading stockist and distributor of the EnDura® range. The unique configuration of the EnDura® range makes it particularly suitable for extreme temperature conditions, which could be highly beneficial for industries like Oil & Gas, where the equipment often operates in challenging environments. Seals made from the […]
Read MoreCompression Set
What is a compression set? In a nutshell, the compression set of a material is the permanent deformation remaining after the removal of a force that was applied to it. ‘Set’ is a term that is used to characterize something that had been deformed by a force and when released does not fully return to its original shape, it has […]
Read MoreElastomers for Food Water and Dairy
Food-grade Rubbers for Hygienic Industries M Barnwell Services understand the specific and very demanding requirements sealing materials must meet in Food, Dairy, and Water industries. Over the last 50 years, we have gained knowledge and expertise in chemically resistant food grade elastomer seals for use with hostile media observed in Clean-in-Place (CIP) and Steam-in-Place (SIP) routines and high-temperature steam sterilisation. […]
Read MoreViton™ O Rings vs Nitrile O Rings
Comparison of two of the most commonly used elastomers – Viton™ O Rings vs Nitrile O Rings As two of the most widely used elastomers, Viton™ (FKM/FPM) and Nitrile (NBR) have some great properties. Both provide a supreme compression set and have an extensive range of purposes in both domestic and industrial installations. Nevertheless, they’re not totally equal in their […]

Read MoreThermal 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 […]
Read MoreWet Chemical Process
Semiconductor Manufacturing – Wet Chemical Process Electro or Electroless Chemical Deposition Despite the fact that this is a smaller division of the semiconductor chip manufacturing industry, it still plays a crucial role. Wet chemical processes are used in etching, cleaning, and other stages in chip manufacturing. Wafers can be cleaned and rinsed after the first wafer preparation. In this stage, […]
