Is there a difference between flame resistant and flame retardant and what is it? And are cable ties heat resistant, fire resistant or fire retardant?
When working in any environment that poses a risk of fire, for example electrical installations both domestic and commercial, it is vital to understand the difference between the terms that are commonly used when referring to fire safety. Many people think the following terms all mean the same thing but they do not, and in fact each refers to a defined level of protection against fire and heat.
It is understanding the differences between these phrases that is key to using the safest equipment possible, and this easy-to-follow guide will help to break down those differences for you.
What is the definition of flame resistant?
When an item is described as flame or fire resistant, it means it will not be affected by flames. Items labelled flame resistant will withstand heat and therefore prevent the spread of fire.
What is the definition of flame retardant?
Items classified as flame retardant have been treated with a chemical that will react when in contact with flames to slow down the flame. Flame retardant items are not flame resistant.
What is the definition of heat resistant?
Heat resistant items will operate normally at higher temperatures but may not operate normally in a fire.
Flame-resistant stainless steel cable ties
All our stainless steel cable ties are manufactured from 316 stainless steel which has a tolerance of temperatures up to 538°C (1000°F). The high melting point of stainless steel 316 (1375-1400°C/2500-2550°F) renders them both fire retardant and fire resistant. Our stainless steel cable ties comply with the 18th Edition of the IET Wiring Regulations (BS7671)
Flame retardant cable ties
Flame retardant cable ties such as our nylon 6/6 range offer not only good chemical resistance but also low smoke density and are the ideal solution for situations where there may be the potential for direct exposure to flames. Our nylon 6/6 cable ties meet the standard UL94.
Flame retardant heat shrink tubing
Our heat shrink tubing is manufactured from polyolefin, a synthetic polymer which is highly flame retardant and offers temperature resistance up to +135°C (275°F). Our range of heat shrink tubing complies to UL standard 224 VW-1.
Heat resistant cable ties
A flame-resistant cable tie is designed for environments where there is exposure to heat and fire. Our UV and heat stabilised cable ties are intended for use in prolonged exposure to extreme temperatures and will tolerate temperatures up to +120°C (240°F). These heat resistant cable ties meet UL standards for electrical applications, which assess the flammability of materials.
If you are operating under any conditions where extreme temperatures and/or fire need to be considered, ensure you have the right equipment and accessories by calling our experienced sales team on 01623 706241 or send us an email to sales@cableties-online.co.uk
