Interpretation of the difference between safety film and blast resistant film
Are construction blast resistant films and construction safety membranes the same? Many people don’t understand the difference between safety membrane and blast resistant film. They feel that these two membranes are just called differently, and their performance and functions are the same. Among them, this is a very serious misunderstanding. Since these two membranes Different names must have reasons and meanings that can support their own different names. Today in the editor, I will briefly explain the difference between safety film and blast resistant film for you, and teach you how to distinguish.
1. Use materials
First of all, we talk about the difference between the two in terms of the thickness of the film and the materials used. The thickness of the safety film is between 100-175 microns (approximately 4-7mil), and the thickness of the blast resistant film is above 250 microns (approximately 10mil), so the best way to distinguish the two films is to compare the two. The thickness of the film. The blast resistant film on the material used is laminated with a special process to make a multilayer polyester composite film. Therefore, in terms of production process and thickness, the blast resistant film is higher than the safety film.
2. Use materials
Secondly, we are different from the protection level and protection concept of the film. As the name suggests, the safety film can help us prevent or reduce the occurrence of personal injury caused by glass breaking. It can only simply prevent the splashing of glass fragments caused by glass breaking, and its real protection level is relatively low. The blast resistant film can withstand the impact of stronger energy. The combination of high-end blast resistant film and glass can even reach the bulletproof level. The protective function of the blast resistant film covers the effect of the safety membrane while reaching the level of safety and explosion-proof. Therefore, the price of anti-explosion film is higher among many car films in the automotive film market.
3. Implementation standards
Finally, we distinguish the difference between the safety film and the blast resistant film from the performance standard of the film. As long as the safety film can prevent or reduce the damage to the human body due to glass breakage, the German standard is DIN53337, the British standard is BS6064, the Italian standard is ANSI Z97.1, and the European standard is EN12600. These are international standards. Standard or national standard. Most of these standards are to prevent "glass shattering", causing people in the car to be injured by glass shards.
The testing standards of blast resistant films are based on preventing penetration. For example, the testing standard of German blast resistant film is DIN52290, the standard of American blast resistant film is UL972, the standard of British blast resistant film is BS5544, and the standard of European blast resistant film is EN356, etc., even if the glass is broken or broken by impact, the blast resistant film will not be penetrated if it meets these standards.
With the development of economy, the application of construction blast resistant films and construction safety membranes has become more and more extensive. The above three points are the differences between safety film and blast resistant film that I briefly introduced to you. If there is something wrong, please correct me.
