Ozone Resistance - an overview | ScienceDirect Topics

Ozone resistance coined with sulfur vulcanizability was the incentive for the development of high molecular weight rubbery isobutylene–β-pinene copolymers. 65 Isobutylene/β-pinene monomer charges readily copolymerize (for example with ‘H 2 O’/EtAlCl 2 /EtCl/−50 °C to −130 °C) to give random structures containing the β-pinene moiety (2), i.e. a structural element that may be

NITRILE Rubber (NBR, Buna-N, Nitrile) Nitrile is the most widely used elastomer in the seal industry. The popularity of nitrile is due to its excellent resistance to petroleum products. It has good physical properties and is superior to most rubbers in regards to compression set, tear and abrasion resistance.

Elastomer Material Types ASTM | Precision Polymer Engineering

The hydrogenation process of NBR elastomers provides excellent heat and ozone resistance. Peroxide cured HNBRs have the best compression set and heat resistance, and high-nitrile (ACN) HNBR elastomers have better resistance to mineral oils. HNBRs coine best resistance and low temperature flexibility, although they are more expensive than NBRs.

Diaphragms - Silicone Rubber Diaphragm Manufacturer from

NBR can stand working temperatures from -10 °C up to approximately 90°C on a continuous basis, and higher temperatures intermittently. NBR resists aging caused by heat very well. NBR''s resistance to sunlight is very poor however abrasion and tear resistance of NBR is very good. NBR seals are most commonly used with the following media:

Material Properties of EPDM, NBR, and FPM Rubber Seals

A lip sealing ring constitutes the seal between socket an spigot end. The lip sealing ring ensures quick and efficient jointing of the pipe system while providing a tight seal in case of both pressure and vacuum. BLÜCHER sealing rings are available in three different rubber qualities, EPDM, NBR, and FPM.


Ethylene propylene diene monomer (EPDM) is a copolymer of ethylene, propylene and a small amount of non-conjugated diene monomers (3 – 9 percent) which provide cross-linking sites for vulcanization: The diene is usually dicyclopentadiene, ethylidene nobornene, or 1,4 hexadiene. These terpolymers can be vulcanized by traditional techniques.
