A Brief Description Of Wood Flame Retardant Wood is a porous and complex natural organic material mainly composed of cellulose, hemicellulose and lignin. Its characteristics are: it does not dissolve or melt under normal processing and use conditions, so the processing method is different from synthetic polymers; wood molecules contain a large number of hydroxyl and hydroxymethyl and other oxygen-containing polar groups, …

In The Laboratory: Compounding Solutions The current trends indicate an oversupply of raw materials, a situation that could last for some time. With a large amount of resin on the market, chemical companies are cutting their research and development budgets. This could force compounders to fill the cap, meaning they will have to perform more testing. They may lean on distribution partners for technical assistance. The …

Features Of Wood Flame Retardant 1: High flame retardant effect, which can prevent flame burning and suppress smoldering (flameless burning, red hot burning);2: The flame retardant itself is non-toxic and does not pollute the environment during production and use. The pyrolysis products of flame-retardant wood should have less smoke, low toxicity, non-irritating and non-corrosive;3: Long-lasting flame retardant…

Characteristics Of Flame Retardant Masterbatch 1. Easy to use: flame retardant masterbatch (masterbatch) is mostly tablet-like or strip-like tablet-sized particles, which are exactly the same size as general plastic particles, which improves the compatibility between them, makes it easier to disperse and add, and is hygienic And reduce volatile waste.2. Good compatibility with resin: In general, the flame retardant masterbat…

Magnesium Hydroxide Magnesium hydroxide is the second largest sales volume of inorganic hydroxide flame retardants. It is a white to light white lens powder with a relative density of 2.4 and a Mohs hardness of 3.0. When heated to above 450°C, the weight will be reduced by 30.9% (mass fraction) due to the loss of water. When magnesium hydroxide is used as a flame retardant, its purity requirements …

Aluminum Hydroxide (ATH) Aluminum hydroxide is one of the most widely used flame retardants. It is a non-toxic, white to light white powder with a relative density of 2.42 and a Mohs hardness of 3.0. When the temperature is heated to higher than 320°C, aluminum hydroxide loses 34.6% of its weight due to water loss. For polymers whose processing temperature is lower than the decomposition temperature of …
