Introduction to PVC pipe-2 PVC can be divided into soft PVC and hard PVC.Hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3. Soft PVC is generally used for the surface of floors, ceilings and leather, but because soft PVC contains plasticizer (this is also the difference between soft PVC and hard PVC), the physical properties are poor (such as the water pipe needs to withstand a …

WHY DO WE NEED FLAME RETARDANTS? On average, there are more than 4,500 fatalities annually in the EU-27 as a result of fires; this accounts for 2% of all fatal injuries. Fires develop from inception through build-up, until a stage where the total thermal radiation from the fire-plume, hot gases and hot compartment boundaries cause the radiative ignition of all exposed combustible surfaces within the compartment…

WHAT ARE FLAME RETARDANTS? Flame retardants are compounds, which when added to materials during or after manufacture, inhibit or suppress the combustion process.They interfere with combustion at various stages of the process, e.g. during heating, decomposition, ignition or flame spread. Their primary function is to suppress the spread of fires or delay the time of flashover so that people can escape.Flame…

About fire retardant coatings Types of fire retardant coatings can be defined in many ways and can usually be classified as follows: From the base material it uses, it can be divided into organic type and inorganic type. The organic type fireproof coating is based on natural or synthetic organic resin and organic emulsion; the inorganic type fireproof coating is based on the inorganic adhesive. According to …
