Common knowledge about microcapsules flame retardants for plastics

Plastics are widely used in industry, agriculture and daily life. However, almost all plastics are easy to burn, and some of them will produce a large amount of harmful gas and smoke when burned. Therefore, the flame retardancy and flame retardancy of plastics are a major problem.In the flame retardant technology of plastics, adding flame retardants is a commonly used method at present. According to rough statistics, 65% to 70% of the world's flame retardants are used for flame retardant plastics.

The application of microencapsulation technology in flame retardants is a new field of science and technology developed in recent years.

Microcapsules, also known as microspheres, are tiny containers that use synthetic polymer materials to wrap solid particles or liquid droplets.The wrapping membrane is called the wall material, and the wrapped material is called the core material.Applications, the preparation of microcapsule by mixed with polymer material or other material, on a substrate is used, by means of radiation heating, pressure or make the micro capsule rupture, releasing the package material, produce the desired performance, or does not destroy the cyst membrane, the package material to the outside through cyst membrane diffusion release, control performance.

The advantage of microencapsulation technology lies in that the capsule core is enveloped and isolated from the external environment during the formation of microencapsulation, so its properties can be preserved without any influence, while under appropriate conditions, the capsule core can be released when the wall material is destroyed, which brings a lot of convenience to the application.
