Nullifire introduces sealant solution for CPVC materials

26 August 2021

NULLIFIRE HAS launched a sealant solution specifically for CPVC materials, offering up to 120 minutes of fire resistance. It also benefits from a distinct blue shade for easy on-site identification and traceability.

FS719 HP Blue for CPVC is described as “a powerful product” designed to close CPVC only when the pipes are deteriorating under fire conditions. This FBC-approved compatible product is rigorously fire-tested (only on CPVC pipes) to EN 1366-3.

Nullifire’s European fire stopping technology manager Ian Outram said: “FS719 HP Blue for CPVC has been developed to address a very specific issue between CPVC and its compatibility issues with other construction products. Our testing offers the assurance of up to 120 minutes of fire resistance.”

Outram continued: “FS719 remains inert until exposed to a specific temperature. The temperature increase will then trigger FS719 to expand, but only if the CPVC pipe is degrading, sealing any gap left by the degraded CPVC sprinkler pipe in the process and ensuring the fire compartment line is maintained. It’s a versatile and easy-to-apply solution for installers of fire protection and sprinkler systems in the UK.”

Chemically compatible with all CPVC pipe types, FS719 is tested for use around 1”, 2” and 3” internal diameter CPVC pipes or up to 90 mm external diameter pipes through flexible and rigid walls, as well as rigid floors.

Fire stopping portfolio

FS719 can be used directly within substrate or Nullifire FB750 Intubatt Coated Batt when installed in full accordance with the manufacturer’s testing methods and recommendations. The CPVC pipes are additionally tested offset within openings, with a reduction in annular of the FS719 down to 5 mm at a single point, provided the minimum 20 mm annular is achieved on the opposite edge of the pipe circumference.

FS719 HP Blue for CPVC is the latest product to join Nullifire’s extensive fire stopping portfolio.

Outram stated: “Like all of our fire stopping products, FS719 HP Blue for CPVC has been launched having undergone rigorous trials and evaluations in line with our focus on excellence within the passive fire protection market. This stringent approach is combined with client support from Nullifire’s team of technical experts. Those experts have years of experience supporting the specification and installation of our products, as well as full specifier and contractor training programmes to ensure the right outcome. In short, everything is focused on providing what our customers need at every stage of their project. That’s smart protection.”
