Introduction
PVC-U Domestic and general trunking
PVC-U Domestic and general
trunking
POLYVINYLCHLORIDE UNPLASTICISED (PVC-U) is one of the most successful modern synthetic materials. It makes excellent
use of scarce resources, is long-lasting and safe in production, use and disposal. PVC-U cable containment is easy to install,
light to handle and very cost-effective. It is an excellent choice of material for the majority of commercial, education and
healthcare environments and has been more thoroughly researched than almost any other synthetic material.
Recycling and sustainability
• PVC-U is a cost-effective, sustainable choice and comparable with other materials such as steel,
aluminium, copper and wood.
• 100% recyclable material.
• Long life cycle.
• Excellent weather resistance.
• No painting or powder coating required.
EMC properties
Some PVC-U systems are available with a coating that provides effective screening against
electromagnetic interference with no reduction in cable capacity.
Fire performance
• The fire rating for PVC-U is excellent* and PVC-U has all the characteristics required for Fire Escape Time.
• Highly resistant to ignition.
• Does little to contribute to the spread of fire and is classified to Building Regs: Class 0.
• Has a low rate of smoke production during the early stages of a fire.
• Acts as an effective barrier to flame spread from malfunctioning electrical components within systems.
• Chars and is self-extinguishing.
• Does not produce flaming droplets or burning debris.
• ABS fittings fire rated to UL94V0.

Environmental
• No increase in dioxin emission from Municipal Waste Incineration.
• No phthalates used in manufacture of PVC-U or FR-ABS.
• Lead-free formulations are used for mouldings and extrusions.
• No use of cadmium-based stabilisers or pigments.
• Lowest oil content of a commodity plastic.
