When it comes to sealing brushes, there are many kinds of materials, such as nylon rubber filaments, nylon flame-retardant rubber filaments, etc. Among them, the sealing brushes made of nylon flame-retardant rubber filaments are also called “flame-retardant sealing brushes” in the industry. Mostly common. However, when it comes to flame-retardant sealing brushes, many people will worry that the sealing brush strips made of brush filaments will be poisonous. So, is the flame retardant sealing brush poisonous? Below, let’s take a look.
In fact, the main difference from the sealing brush made of ordinary rubber wire is that the flame-retardant rubber wire sealing brush is added with flame-retardant and flame-retardant materials; while the ordinary rubber wire uses new plastic particles as raw materials, Without adding any flame-retardant additives, the flame retardant effect is not obvious. The sealing brush has flame retardancy and cannot contain heavy metals and toxic and harmful substances. It needs to use environmentally friendly halogen-free flame retardants and nylon filaments processed and produced from new environmentally friendly raw materials. After burning in this way, it will not produce a non-irritating smell, and it can pass the EU UL94V-0 flame retardant test. For example, AOQUN brand’s flame-retardant sealing brush.
The screen door sealing brush of AOQUN brand has passed the SVHC test and complies with the ROHS EU standard; the sealing brush reaching the UL94-V0 flame retardant level meets the EN45545-2 EU fire retardant smoke toxicity test requirements, non-toxic, low smoke, and pass Bombardier smoke density test.
On the contrary, many low-priced and cheap ones on the brush market are under the guise of saying that the sealing brush made of flame-retardant nylon glue contains heavy metal components that seriously exceed the standard, and the flame-retardant effect is quite poor. , The smell produced after burning is a serious hazard to human health. This is why more and more people are paying attention to the safety and environmental protection of sealing brush products.
To sum up, the sealing brush that complies with the ROHS EU standard and can also reach the flame-retardant level of UL94-V0 is non-toxic and not easy to burn. on the contrary. Those so-called “flame-retardant sealing brushes” on the market that claim to be highly flame-retardant and low in price are likely to be false. Therefore, when faced with the purchase of sealing brushes, it is recommended to find a reliable manufacturer of sealing brushes.
