Rubber, vulcanized — Guidelines for material specification

Edition date: 2020-07-15
In Force
Available languages: French, English
Summary:

This document establishes guidelines for the specification of vulcanized rubber based on the properties of individual rubber types. This document helps users of rubber products, who are not rubber experts, to create a specification for the rubber materials they wish to use.

It also describes a designation system to enable a line call-cut code to be devised for each specification.

Since the properties of rubber depend on the type of rubber, such as composition, some rubbers are classified into several types and organized by hardness.

Representative specifications for the following rubber types are given in Annexes B to M: natural rubber (NR), styrene butadiene rubber (SBR), nitrile rubber (NBR), hydrogenated nitrile rubber (HNBR), nitrile rubber mixed with PVC (NBR/PVC), chloroprene rubber (CR), ethylene acrylic rubber (AEM), fluorocarbon rubber (FKM), silicone rubber (VMQ), epichlorohydrin rubber (ECO) and ethylene propylene rubber (EPM and EPDM).

In cases of mixed rubber polymers, the main polymer in the rubber material gives the name of the rubber type.



Le présent document donne des lignes directrices pour la spécification d'un caoutchouc vulcanisé sur la base des propriétés de types particuliers de caoutchouc. L'objectif du présent Rapport technique est d'aider les utilisateurs de produits en caoutchouc, qui ne sont pas des experts en caoutchouc, à créer une spécification pour les matériaux en caoutchouc qu'ils souhaitent utiliser.

Il décrit également un système de désignation permettant d'établir un code de sélection pour chaque spécification.

Comme les propriétés d'un caoutchouc dépendent du type de caoutchouc, telle que sa composition, certains caoutchoucs sont classés en plusieurs types et organisés selon leur dureté.

Les spécifications représentatives des types de caoutchouc suivants sont données dans les Annexes B à M: caoutchouc naturel (NR), caoutchouc styrène-butadiène (SBR), caoutchouc nitrile (NBR), caoutchouc nitrile hydrogéné (HNBR), caoutchouc nitrile-PVC (NBR/PVC), caoutchouc chloroprène (CR), caoutchouc éthylène acrylique (AEM), caoutchouc fluorocarboné (FKM), caoutchouc silicone (VMQ), caoutchouc épichlorhydrine (ECO) et caoutchouc éthylène propylène (EPM et EPDM).

Dans le cas de coupages de polymères, le polymère principal dans le matériau caoutchouc donne le nom du type de caoutchouc.
