Flame retardant (HFFR) in glass fiber reinforced PA6 PA6 glass fiber reinforced composite material uses glass fiber as a filler, which does not improve the flame resistance of the composite material because of the high flame retardant properties of glass fiber. Easier to burn.The wick effect of PA6 glass fiber reinforced materialThe so-called "candle wick" effect means that the candle needs a wick to burn. It originated …

The necessity of Ca Zn stabilizer PVC pipe is a plastic pipe that is very popular in the world. Affordable prices and diverse functions are the main reasons why people choose PVC pipes as piping systems in their homes. From the manufacturer`s point of view, PVC is not an easy pipe to produce because PVC material itself is a plastic that is very sensitive to temperature. When the production temperature is not rea…

The Function of PVC Stabilizers Without the addition of a stabilizer, PVC resins begin to degrade at temperatures of 160°C or more, the main re-action being dehydrochlorination.The results of measurement of the chlorine in the hydrogen chloride gas produced by the degradation of PVC during heating shows, as can be seen, the addition to the resin of a lead stabilizer reduces the amount of hydrogen chloride prod…

New trends in PVC stabilizers for PVC pipe The PVC pipes are currently manufactured using a wide range of stabilizer systems. European market was historically based on Lead stabilizers that have been entirely replaced by COS (Organic-based and/or Calcium-Zinc stabilizer) systems thanks to the Voluntary Commitment of the European Stabilizer Producers Association within the Vinyl 2010–Vinyl Plus initiative.The North Ameri…

Three Surprising Benefits of Using Flame Retardant at your House Flame retardants are products in a home that contain chemicals to decrease or eliminate their flammability, and they work in three different ways to inhibit or minimize the severity of a fire. A flame retardant will decrease the presence of oxygen as well as gasses located close to items that are burning. It will inhibit a material’s ability to ignite. Flame retardants also pro…

What are the protective benefits of flame retardants? Flame retardants play a unique role in fire prevention and fire safety. They not only prevent fires from starting, but if a fire does occur, they slow down the spread of the fire and improve the opportunity for safe escape. Their role in delaying flashover, for example, is especially critical to escaping the deadly consequences of fire. Flashover occurs when every flammable obje…

Flame Retardant Classification 1. How many types of flame retardants are in the market?There are many classification methods for flame retardants, which are divided into inorganic flame retardants, including magnesium hydroxide, aluminum hydroxide, and antimony trioxide. The most commonly used ones are mainly used as synergists and other flame retardants will be better. If used alone, the amount will be large…

Brief introduction of Lead stabilizer History“Like tin and iron, lead is among the longest-known metals, and was made mention of already in the Old Testament”, the famous chemist Dr J. Jakob Berzelius, a professor at the Royal Swedish Academy of Sciences, wrote in his chemistry textbook in 1824.Lead is easy to mine and both pure lead and lead alloys have favourable mechanical properties. In addition, lead can be f…
