ETFE (ethylene tetrafluoroethylene) is a material that is gaining popularity in the construction industry due to its numerous benefits. While ETFE has been known for creating lightweight and durable roofing solutions, it is now being used for more than just its aesthetic qualities.
One of the most notable benefits of ETFE is its exceptional security properties, which have made it a go-to material for security applications.
This article will discuss the top 7 benefits of ETFE regarding security.
ETFE is highly fire-retardant, which means it is less likely to catch or propagate flames, reducing the risk of spreading fire in an emergency. This is due to its self-extinguishing properties that help prevent fires from spreading.
ETFE has a melting point of approximately 260°C. In the event of a fire, ETFE does not promote the spread of flames because it self-extinguishes and does not generate any flaming droplets or particles.
If hot gases or flames come into contact with ETFE cladding forming part of the building envelope, it will melt and shrink back from the area affected, allowing hot gases and smoke to be vented.
The venting of internal spaces consequent to this effect can contribute to the overall fire safety of a building complex.
ETFE has been tested to various international and national standards.
- Under AS1530.2, ETFE has a Flammability Index of 1
- Under AS1530.3, ETFE has an Ignitability Index of 0, Spread of Flame Index of 0, and Smoke Developed Index of 1
The fire rating of ETFE to British and European Standards (which are very detailed in their rating) is class Bs1d0:
- BS476 6&7 class 0: a material of limited combustibility
- EN 13501-1 EUR Class Bs1d0: means ETFE is a combustible material with a minimal contribution to fire with a weak quantity/speed of smoke emission and no dripping of flaming droplets.
ETFE is highly resistant to chemicals, making it an excellent choice for harsh environments where chemical exposure is a concern. This property allows ETFE to withstand acid rain, exhaust fumes, and other corrosive substances, making it suitable for high-security areas such as industrial facilities.
ETFE offers excellent chemical resistance to various substances, including acids, bases, and organic solvents. It can withstand exposure to these chemicals without significant degradation or loss of mechanical properties. This makes it ideal for harsh chemical environments where other materials may fail.
ETFE is highly resistant to various sulfuric, nitric, and hydrochloric acids. It can withstand exposure to these acids without significant degradation or loss of mechanical properties. This makes it an ideal material for chemical processing, where acids are commonly used in various applications.
ETFE is also highly resistant to a broad range of bases, including sodium hydroxide, potassium hydroxide, and ammonium hydroxide. It can withstand exposure to these bases without significant degradation or loss of mechanical properties. This makes ETFE an ideal material for use in the pharmaceutical and chemical processing industries, where commands are commonly used.
ETFE is highly resistant to various organic solvents, including alcohols, ketones, and esters. It can withstand exposure to these solvents without significant degradation or loss of mechanical properties. This makes it an ideal material for use in the chemical and pharmaceutical industries, where organic solvents are commonly used.
ETFE is highly resistant to UV radiation, which can cause other materials to deteriorate or become discolored over time. This makes ETFE an excellent choice for outdoor applications, such as skylights, that require high levels of UV protection.
Highly Resistant to Impact
ETFE is highly resistant to impact and can withstand damage caused by hail, snow, and even explosives. Unlike traditional glass, ETFE can absorb high levels of impact without shattering, making it an ideal solution for protecting buildings from physical attacks.
Tear and Puncture Resistance
ETFE is highly resistant to tearing and puncturing, which means it can withstand the impact of high-velocity projectiles, such as bullets or rocks. This makes it an excellent choice for security applications, such as ballistic-resistant windows or protective glazing.
With a shallow mass, ETFE cushions limit the reverberation within a room by absorbing the acoustics. The same sound levels within an enclosure will depend on the properties of the cushions and the project (e.g., the size/scale of the room, the incline of the pillows, the materials used inside, and the span of the pads).
ETFE has excellent soundproofing properties, making it a perfect choice for buildings requiring high noise reduction levels. This property can help reduce the impact of external noise, such as traffic, and improve the overall comfort of occupants.
ETFE has excellent durability and is resistant to wear and tear. It is much stronger than glass and other plastic materials and can withstand impacts and heavy loads. The material is highly flexible and can be formed into various shapes without losing strength, making it an excellent choice for complex designs.
In conclusion, ETFE is an excellent choice for security applications due to its numerous benefits. Its properties make it highly resistant to impact, fire, chemicals, UV radiation, and tearing and puncturing. Additionally, its energy efficiency, soundproofing properties, durability, design flexibility, and cost-effectiveness make it a superior choice over other materials.
