Flame retardant is a functional additive which gives flame retardancy to flammable polymers. It can be widely used in flame retardant of fabrics, wood, plastics, rubber, polyurethane and so on. Sometimes when using flame retardant, there will be flame retardant failure. What are the causes of flame retardant failure after using flame retardant? The following is a brief introduction to you.

1. Different flame retardants. Different flame retardants have different retention time, such as one-off flame retardant and durable flame retardant, water-based flame retardant and flame retardant varnish have different flame retardant effect and failure time, so it is obvious that the flame retardant effect and effective time of wood treated with flame retardant varnish are longer.

2. Use method of flame retardant. There are two kinds of flame retardants: internal and external. The internal flame retardant is mixed and stirred before the flame retardant is formed. The external flame retardant is soaked by physical method and sprayed. The effective time of the flame retardant added in obviously is longer and better.

3. Environmental factors. The storage environment of the treated flame retardants is different, and the effective time of flame retardant is different. For example, indoor and outdoor, due to the influence of sunshine, temperature and air, the outdoor failure rate is obviously faster than indoor failure rate.

4. Flame retardant treatment time is too long. If the fabric is more than half a year or more away from the last flame retardant treatment, the flame retardant effect will be worse or ineffective compared with the initial flame retardant treatment.

These are the reasons for the failure of flame retardants after using flame retardants. I hope it can help you. If you have any other questions about flame retardants, you can contact us at any time. We will serve you wholeheartedly!
