![]() ![]() R391 compound is coloured reddish brown and has an unlimited shelf life under normal conditions of wrapping and storage. R391 can be used to seal cable ends or cable entries to enclosures. It has no deleterious effect on metals and plastics or on natural rubber, synthetic rubber, PVC or other cable materials. The compound is highly resistant to water permeation, acids and alkalis in liquid or vapour form under normal conditions. 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 material does not liberate toxic fumes even if overheated and is harmless to the hands. The compound is non-hardening and so can be readily moved and replaced for maintenance purposes. 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. R391 does not harden on exposure to air or sunlight and does not shrink crack or peel. Pack & Seal Red has been designed so that its use is easily visible while Pack & Seal Clear has been manufactured to be so transparent that it is possible to read PCB labels through it. There is a red fire retardant version and a clear version. Putty ESC is a safe and feasible adjunct to conventional sternal closure with stainless-steel wire cerclage. Our fire and electrical putty pads are moldable, non-curing, single component and. Pack & Seal Electrical Sealant Putty comes in two versions. 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. HydroFlame putty pads are a membrane-penetration firestop system. ![]() It is easy to apply and will stay resilient (will not harden). R391 compound can be also used for many non-electrical applications whenever a reliable non-hardening moisture or water seal is required. Putty Pads are specifically designed to maintain high acoustical ratings in fire rated walls. 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. Pictured:Prysmian R391 Weatherproof Plastic Compound 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 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.
