Silicone Hose vs Rubber Hose: Which Is Better for Your Application?
Silicone Hose vs Rubber Hose: Which Is Better for Your Application? Silicone hose is the better choice for high-temperature performance applications — track days, motorsport, intercooler pipework, and sustained industrial heat above 125°C. Standard rubber hose, typically EPDM, is the correct choice for everyday road vehicles, general cooling systems, and most industrial fluid handling where […]
Food Grade Silicone Rubber for Food Processing: Properties, FDA Compliance, and Why Engineers Choose It
Food Grade Silicone Rubber for Food Processing: Properties, FDA Compliance, and Why Engineers Choose It Food grade silicone rubber is a platinum-cured or peroxide-cured elastomer formulated specifically for direct and indirect contact with food, beverages, and pharmaceutical products, complying with FDA 21CFR177.2600 and EC 1935/2004. Unlike standard industrial silicone, food grade formulations are manufactured using […]
Rubber Seals and Gaskets for Electric Vehicles: Which Materials Do Engineers Specify?
Rubber Seals and Gaskets for Electric Vehicles: Which Materials Do Engineers Specify? Rubber seals and gaskets for electric vehicles must meet a substantially more demanding specification than those used in conventional ICE powertrains. EV battery packs, power electronics, and motor assemblies operate at elevated temperatures, carry high-voltage cabling, and are exposed to glycol-based coolants, thermal […]
Electrical Safety Matting: IEC 61111 Classes Explained — Which Class Do You Need?
Electrical Safety Matting: IEC 61111 Classes Explained — Which Class Do You Need? Electrical safety matting is specialist rubber insulation matting designed to protect personnel working on or near live electrical equipment by providing a dielectric barrier between the operative and earth. Governed in the UK by BS EN 61111:2009 (the British adoption of IEC […]
EPDM vs Neoprene vs Nitrile vs Silicone vs Viton: Which Rubber Is Right for Your Application?
EPDM vs Neoprene vs Nitrile vs Silicone vs Viton: Which Rubber Is Right for Your Application? Choosing the wrong rubber compound for a seal, gasket, or sheet application does not just risk premature failure — it can mean unplanned downtime, chemical contamination, or a safety incident. The five most widely specified industrial rubber materials in […]
EPDM Rubber: Properties, Uses and Grades Explained
EPDM Rubber: Properties, Uses and Grades Explained EPDM rubber is a synthetic elastomer made from ethylene, propylene, and a diene monomer — most commonly ethylidene norbornene (ENB). The saturated polymer backbone produced by the ethylene-propylene chemistry gives EPDM its defining characteristic: outstanding resistance to ozone, UV radiation, weathering, steam, and hot water. It is the […]
Nitrile vs Viton Rubber: Which Seal Material Should You Specify?
Nitrile vs Viton Rubber: Which Seal Material Should You Specify? Nitrile (NBR) and Viton (FKM) are the two most widely specified elastomers for oil and chemical sealing applications — but they are not interchangeable, and choosing the wrong one is an expensive mistake. Nitrile is the standard choice for petroleum oil, hydraulic fluid, and fuel resistance up […]
Shore Hardness Explained: Which Rubber Hardness Do You Need?
Shore Hardness Explained: Which Rubber Hardness Do You Need? Shore hardness is a standardised measure of a rubber’s resistance to permanent indentation — expressed as a number from 0 to 100 on either the Shore A or Shore D scale. The higher the number, the harder the material. For rubber and elastomers, Shore A is […]
