Materials. Profiles. Applications.Clear or translucent elastomer grommets provide edge protection while offering a different appearance from opaque parts. They may be useful where visibility or a particular finish is…
EPDM grommets are molded components for suitable panel, cable-protection or sealing applications. EPDM is also used in other kinds of products, but a roof membrane, belt or…
An electrical wire grommet helps protect a cable jacket from the edge of a panel opening. Select the part from the specified mounting-hole size, panel-thickness range and…
Electrical rubber grommets help protect cable insulation from abrasion where wires pass through a panel. The grommet covers the edge of the opening and separates it from…
An electrical cord grommet provides a protective surface where a cable passes through a panel. It helps reduce abrasion of the cable jacket at the opening. It…
A black rubber grommet provides a protective surface where a cable passes through a panel opening. The color is an appearance choice; it does not establish the…
Excessive heat exposure during curing can leave some rubber compounds unable to meet their required properties. The extent of damage must be assessed from the process history…
Reversion in a sulfur-cured compound involves a loss of effective network structure during excessive heat exposure. Its extent depends on the polymer, cure formulation and time-temperature history.
A rubber grommet can lose required properties during storage or service through several aging mechanisms. Network degradation may contribute, but a sticky surface or color change alone…
This article discusses reversion in sulfur-cured rubber: a loss of effective crosslink structure during excessive heat exposure. It can affect the properties of a molded part. Reversion…
