How to make polycarbonate fire resistant and straightforward?

Polycarbonate is a sort of designing plastic with fantastic execution and wide application. It has incredibly high straightforwardness, and the light conveyance can reach 89%. It can meet numerous application situations with high prerequisites for optics and variety. Besides, it makes a specific fire resistant difference, which can arrive at V-2 fire resistant. It is a self smothering designing plastic.

Notwithstanding, in some application situations, it is important to accomplish a V-0 fire resistant of 1.6 mm or even 0.8 mm, for example, cell phone cases and other electronic items, PC films, PC plates and different fields, and furthermore to keep up with the straightforwardness of the PC, which has specific challenges. Nonetheless, the utilization of fire resistant can additionally work on the fire resistant level of the PC.

As of now, the fire retardants utilized for PC chiefly incorporate phosphate, natural silicon and sulfonate. Phosphate fire retardants (like BDP and RDP) should be included an enormous sum to hinder PC, which is inclined to trickling. Hostile to dribbling specialists should be added, which will truly influence the straightforwardness of PC. The sulfonic corrosive salts and organosilicon fire retardants can keep up with the high straightforwardness of PC.

1、 Sulfonate fire resistant

Sulfonate fire resistant has a place with soluble earth metal salt, which has high fire resistant effectiveness for PC items. The usually utilized assortments are chiefly sodium 2,4,5-trichlorobenzenesulfonate (STB), potassium phenylsulfonyl benzene sulfonate (KSS), and potassium perfluorobutylsulfonate (PPFBS). STB contains chlorine, which is generally utilized in non straightforward PC frameworks.

Fire resistant system of sulfonate fire resistant:

At high temperatures, sulfonates can advance the isomerization of PC, discharge carbon dioxide and water during burning, advance the age of phenols, advance the age of aliphatic and sweet-smelling accumulates, speed up the carbon development pace of PC particles, and advance the cross-connecting of polymer particles.
