What is EPDM O-ring?
EPDM o-rings, or ethylene propylene o-rings, are a family of synthetic elastomers with lower cost steam and chemical resistance, particularly for applications involving solvents, acids and other mild chemicals.
What is a Buna O-ring?
Nitrile rubber (NBR) o-rings, also known as Buna-N, are one of the most commonly used sealing elastomers due to resistance to petroleum-based fuels and lubricants and its relatively low price. Nitrile elastomers are copolymers of acrylonitrile and butadiene. There are a number of common variations of nitrile compounds.
What are nitrile o-rings used for?
You’ll find nitrile o rings used in many applications, including where oil resistance is needed or where low temperature functionality is required. These include automotive, aircraft fuel systems, marine applications and more.
What are the ozone compatible materials?
Ozone Compatible Materials Material Rating Material Ethylene-Propylene A PVDF (Kynar) Fiber Reinforced Plastics (FRD) D Santoprene Flexelene B Silicone Fluorosilicone A Stainless Steel – 304/316
What are the storage guidelines for polymer products based on ozone?
Guidelines for the storage of polymer products based on ozone via photo-chemical processes. When equipment ISO 2230 Many polymer products and components are stored for long periods of time before being put into service, so it is important they are stored in conditions that minimize unwanted changes in properties.
How to prevent adhesion between rubber products?
They should be protected by wrapping in, or by separation with, a suitable material, e.g. paper or polyethylene. Contact with dusting powder Dusting powders should only be used for the packaging of rubber items in order to prevent adhesion. In such cases, the minimum quantity of powder to prevent adhesion should be used.
Can the metal part of rubber-to-metal bonded products come into contact with rubber?
The metal part of rubber-to-metal bonded products should not come into contact with the rubber of other products. Preservative used on the metal should be of a type that it will not adversely affect the rubber or the bond to such an extent that it does not comply with the product specification.
