Recently, the supply of phosphate ester flame retardants is tight or even unavailable. It has always been thought that many products in the market are in oversupply, but many products in the flame retardant industry are in short supply.

Organophosphorus flame retardants mainly refer to phosphate ester flame retardants, which are one of the most important varieties of PC/ABS alloy halogen-free flame retardants, with dual effects of flame retardant and plasticization. Its flame retardant mechanism is: on the one hand, it is thermally decomposed to generate phosphoric acid, metaphosphoric acid, etc., which can catalyze the endothermic dehydration of hydroxyl-containing compounds into carbon reaction, so that a dense carbon layer is formed on the surface of the polymer; on the other hand, it is heated to generate PO•, which can Capture H• and HO• to inhibit combustion reaction.

Polycarbonate (PC) is a thermoplastic engineering plastic with excellent mechanical properties, good heat resistance and low temperature resistance, stable electrical properties and good dimensional stability. However, PC has poor processing fluidity, is sensitive to notches, is prone to stress cracking, has poor chemical resistance, and is expensive, which limits its application range. Compatible toughener ST-1 can solve the problem.

The recent plunge in the international crude oil market has impacted the chemical market and the mentality of the epoxy resin industry chain, aggravating the bearish sentiment of the industry. The domestic epoxy resin market continued its downward trend, and the trading on the market did not change significantly. The support of the dual raw materials is weak, and the offer of epichlorohydrin has declined significantly. The support of the other raw material, bisphenol A, is weak, and the epoxy resin is in a downward trend as a whole. There are few market purchases and it is difficult to ship.

Inorganic flame retardants for flame retardant tapes: generally refer to inorganic compounds that are added to the formulation of polymers and have flame retardant or smoke suppression effects. The main components are hydroxide (aluminum hydroxide, magnesium hydroxide), red phosphorus, tin series, borate (zinc borate).

ABS plastics are generally used in traditional household appliance housings. ABS plastic has the characteristics of wide source of raw materials, easy molding and processing and excellent impact performance, and is widely used in automobiles, household appliances and machinery industries.
