How to add aluminum hydroxide to achieve flame retardant

2020-11-30

Safe and environmentally friendly non-toxic, non-polluted inorganic flame retardants are more and more widely used, and the most commonly used flame retardant material is aluminum hydroxide. How should aluminum hydroxide be added to achieve the flame retardant ?

The consumption of aluminum hydroxide ranks first among flame retardants, and aluminum hydroxide itself has three functions: flame retardant, smoke suppression, and filling.

It can also achieve flame-retardant synergistic effects with a variety of substances, and is called an ideal environmentally friendly inorganic flame retardant;

In particular, it has rich resources and low prices and is favored by customers.
Non-volatile, non-exuding, can be stored in polymer materials for a long time,

When the product is subjected to arc action, it has the characteristics of anti-arc and anti-magnetic; it has good dispersion in the resin, and it is not easy to bend and white when added in a large amount; it has a self-cleaning effect on the calender roller to prevent the resin from sticking and Attached, good molding processing performance.

Calendering is a molding method mainly used for polyvinyl chloride resin, which can produce films, sheets, plates, artificial leather, floor tiles and other products.

When aluminum hydroxide is heated, it produces Al2O3 that loses water, which absorbs heat during gasification, promotes carbonization, and has a better flame retardant effect.

However, aluminum hydroxide also has the disadvantage of a large amount of addition in the use process, usually more than 40% is needed to show the flame retardant effect.
