Where to Use Hoffman
Non-Metallic Enclosures
Designed to safely house electrical and electronic controls in the harshest outdoor and indoor
environments, Hoffman non-metallic enclosures offer effective and economical protection in
these and other commercial and industrial applications:
• Pulp and paper
• Telecommunications
• Marine
• Controls OEM
Performance Comparison
While strength and corrosion resistance may
be primary considerations, other factors such
as impact resistance and ease of modification
may also come into play. This chart provides
basic material comparisons to further help
you select the best non-metallic enclosure
material for your application.

electrical systems in these tough conditions calls for Hoffman
non-metallic enclosures. Not only do non-metallics provide a
low-cost alternative to stainless steel for corrosion resistance,
they’re also lightweight, easy to modify and tough—making them
ideal for indoor and outdoor use.

Corrosion Resistance
The chart to the right provides guidance for
determining the feasibility of using certain
enclosure materials in environments
containing solvents and organics, alkalis and
oxidizers, and acids and neutral salts. Materials
are rated on a scale of Recommended to
Limited Use based upon their performance in
resisting corrosion. However, note that the
enclosure materials listed as Limited Use will
perform well when exposed to certain specific
corrosive agents within the three general
classes. Refer to the detailed Chemical
Resistance Charts in the Hoffman Specifier’s
Guide for complete information.

Where to Use Hoffman
Non-Metallic Enclosures
Designed to safely house electrical and electronic controls in the harshest outdoor and indoor
environments, Hoffman non-metallic enclosures offer effective and economical protection in
these and other commercial and industrial applications:
• Pulp and paper
• Telecommunications
• Marine
• Controls OEM
Performance Comparison
While strength and corrosion resistance may
be primary considerations, other factors such
as impact resistance and ease of modification
may also come into play. This chart provides
basic material comparisons to further help
you select the best non-metallic enclosure
material for your application.

Wet environments. Harsh chemicals. Humidity. Dust and grime.
Ocean air. Protecting vital electronic equipment, instruments and
electrical systems in these tough conditions calls for Hoffman
non-metallic enclosures. Not only do non-metallics provide a
low-cost alternative to stainless steel for corrosion resistance,
they’re also lightweight, easy to modify and tough—making them
ideal for indoor and outdoor use.

Corrosion Resistance
The chart to the right provides guidance for
determining the feasibility of using certain
enclosure materials in environments
containing solvents and organics, alkalis and
oxidizers, and acids and neutral salts. Materials
are rated on a scale of Recommended to
Limited Use based upon their performance in
resisting corrosion. However, note that the
enclosure materials listed as Limited Use will
perform well when exposed to certain specific
corrosive agents within the three general
classes. Refer to the detailed Chemical
Resistance Charts in the Hoffman Specifier’s
Guide for complete information.
