Prysmian R391 Weatherproof Plastic Compound

 

Prysmian R391 weatherproof plastic compound is used to protect electrical connections from moisture and corrosive vapours - Prysmian Components R391 is a non-hardening plastic waterproof sealant with the consistency of putty and good insulating properties. Prysmian R391 compound can be moulded around terminals or connectors, or can be used as a mechanical seal for any form of electrical enclosure.

Prysmian Weatherproof Plastic Compound R391 prevents electrical leakage or short circuits due to dampness - it prevents corrosion of electrical contacts in industrial atmospheres and seals irregular openings, cable entries, screw threads and covers of electrical equipment. R391 compound can be also used for many non-electrical applications whenever a reliable non-hardening moisture or water seal is required.

Prysmian Weatherproof Plastic Compound R391 is soft enough to be readily moulded around terminals or intricate contours or pressed into cavities - it is not sticky but has good adhesion to moulded plastic and other surfaces to resist the dislodging effects of vibration and to prevent moisture creeping along the interface. R391 does not harden on exposure to air or sunlight and does not shrink crack or peel. Exposure to sunlight may cause a slight skin hardening which does not affect the mass, and which can easily be removed by working in the hand. The compound is non-hardening and so can be readily moved and replaced for maintenance purposes. The material does not liberate toxic fumes even if overheated and is harmless to the hands.

Prysmian Weatherproof Plastic Compound R391 consists of an inert filler dispersed in a plastic base - R391 is not resistant to oils, aromatics or aliphatic hydrocarbons. The compound is highly resistant to water permeation, acids and alkalis in liquid or vapour form under normal conditions. It has no deleterious effect on metals and plastics or on natural rubber, synthetic rubber, PVC or other cable materials. R391 can be used to seal cable ends or cable entries to enclosures. R391 compound is coloured reddish brown and has an unlimited shelf life under normal conditions of wrapping and storage.
