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…

Lead stabilizer in PVC production Polyvinyl chloride (PVC), is the most produced plastic polymer in the world after polyethylene and polypropylene. The polymer was discovered in 1872 by Eugen Baumann when he observed that some vinyl chloride in a flask had started to polymerize in a white solid during exposure to the sun. However, the use of PVC in commercial products became more widespread only after the B.F. G…

Classification of lubricants In the plastic molding process, lubricants reduce the friction between the plastic and processing machine, and between the plastic particles, and they are therefore effective for improving the fluidity and mold-release properties of the plastic, and for enhancing the processing efficiency and appearance of the resulting molded article. Some act as external lubricants, and some a…

Characteristics of additives used in the processing of PVC. PVC processing requires the use of many additives, thanks to which it is possible to obtain products for different purposes and with different levels of flexibility.PVC is very easily modified and therefore its properties can be freely customized to very different requirements depending on the intended use.Modification is accomplished through the appropriate selection of PVC ble…

The Formulating PVC Products Before PVC can be made into products, it has to be combined with a range of special additives. The essential additives for all PVC materials are stabilisers and lubricants; in the case of flexible PVC, plasticisers are also incorporated.Other additives which may be used include fillers, processing aids, impact modifiers and pigments. Additives will influence or determine the mec…
