The plastic contains halogen flame retardants
Nearly 80% of the domestic modified plastic used flame retardants as halogen flame retardants, plastic containing halogen flame retardants with polybrominated diphenyl ether and polybrominated biphenyls.
The bromine flame retardants in plastic containing halogen flame retardants are of high efficiency and low dosage, which have little effect on the material performance, and the price of bromine flame retardants is moderate. Compared with other plastics containing halogen flame retardants, the efficiency/price of bromine flame retardant is superior, and 70%~80% of China's export electronic and electrical products are used with such flame retardants.
However, in recent years, some countries in the European Union believe that the flame retardants of bromine will produce the toxic carcinogenic polybromoprene (PBDD) and the polybromo-dibenzofuran (PBDF). The European Union introduced a ban on all electronic and electrical equipment sold in eu countries, which cannot contain polybrominated biphenyls and polybrominated diphenyl ether.
At present, the development of domestic environmental protection type flame retardant has attracted more and more attention. At the same time, people's demand for fire safety and flame retardant products is higher and higher, and no halogen, low-smoke, low-toxic environmental flame retardant has become the target of people's pursuit.
Flame retardant break down to form non-volatile protective film of flame retardants in plastics combustion temperature decomposition, the decomposed product form involatile protective film covering on the surface, to partition the air to prevent burning.
Flame retardant breakdown products cutting the active free radical chain reaction active free radical chain reaction can make flame continues, flame retardant breakdown products cutting the active free radical chain reaction, so as to effectively prevent the fire burning.
The dispersion of combustion heat and the dilution of combustible material are one of the ways to achieve flame retardant. As the heat of combustion is absorbed in large quantities, it reduces the temperature of the plastic, thus slowing down the decomposition of evaporation and combustion. On the other hand, the plastic flame retardant system can be decomposed into non-flammable gases, thus diluting the combustible gas and the flame retardant.

Diphenyl Isooctyl Phosphate (S141,362, DPOP) Product Overview
Chemical Classification: Diphenyl Isooctyl Phosphate, Diphenyl 2-Ethylhexyl Phosphate
Diphenyl Isooctyl Phosphate (S141,362, DPOP) Is An Excellent Flame Retardant Plasticizer That Can Be Used In Most Industrial Polymers Including PVC And Its Copolymers, Nitrocellulose, Ethylcellulose, Poly Methyl Cellulose Methyl Ester, Polystyrene And The Like. Diphenyl Isooctyl Phosphate (S141,362, DPOP) Are Generally Used In The Manufacture Of Vinyl Sheets, Coated Fabrics, Inks, Plastics, Rubber And Plastic Foamed Organic Sol, Adhesives, Vinyl And Conveyor Belts. Due To Excellent Solubility, Improve The Performance Of Many Formulations. In Addition, It Can Be The Final Product It Offers The Following Range Of Interesting Properties Such As Flame Retardancy, Low Temperature Flexibility, Abrasion Resistance, Grease Resistance, Excellent Light Stability And Outdoor Weather Resistance And Excellent High Screen Welding Performance. Due To Its Excellent Solubility, Diphenyl Isooctyl Phosphate (S141, 362, DPOP), And Then 3 Phr Of Bismuth Oxide And 10-20 Phr Of Aluminum Hydroxide Were Added.
Diphenyl Isooctyl Phosphate (S141,362, DPOP) Can Be Used As An Excellent Flame Retardant Material For Transparent Films. In Some Fire-Resistant Harsh Colored Films, It Is Recommended To Add Diphenyl Isooctyl Phosphate (S141,362, DPOP) To Significantly Improve The Light Stability And Outdoor Weather Resistance Of The Film.
(S141,362, DPOP) With Diphenyl Phosphate And Tricresyl Phosphate In The Presence Of 10-15% Of Phthalate Plasticizer Such As DOP, Phosphoric Acid Diphenyl Isooctyl Ester (S141, 362, DPOP) Allows The Resulting Plastic To Have A Low Initial Viscosity And A Good Good False Plasticity And Storage Stability. Due To Its Good Pseudoplasticity And Film-Forming Properties It Is Recommended To Add Diphenyl Isooctyl Phosphate (S141,362, DPOP) To PMMA-Based Plastics And Nitrocellulose Coatings And Inks.
A heavier gas or a high boiling point of liquid oxygen isolation. The water taken out of the reaction absorbs a lot of heat, reduces the surface temperature of the combustible, and vaporized into steam, forming a protective film on the surface of the combustible, thereby achieving the flame retardant.
The process of plastic burning can think like this: in the air, due to external heat or fire make plastic is heated, and eventually led to the degradation, the volatile products, flammable products and thermal energy products, under the effect of external heat source to continue, reaches a certain temperature plastic will burn. Some of the heat from plastic combustion is absorbed by the degradation of plastics through conduction, radiation and convection, and volatilizes more combustible products. On the other hand, in the burning process, the air around the flame is turbulent, increasing the mixing speed of combustible volatiles and air, making the combustion more violent.
The flame retardant of plastic with halogen flame retardants is a kind of substance which can prevent combustion, reduce combustion speed or improve the ignition point.
The dehydration of the decomposition product of flame retardants makes the organic carbonization of organic matter, which prevents the combustion of burning plastic from decomposition and combustion, and usually the single carbon does not produce the combustion of flame and decomposition combustion. Therefore, if the thermal decomposition of the material can be rapidly carried out and not stopped at the combustible material stage and decomposed to carbon, it can prevent combustion.
Eight bromine ether has nothing to do with the quality of the abroad, but to pay more attention to improve the appearance of products, overseas has change from the traditional powder for granular, of collecting main manufacturers in the past two years have been the output granular eight bromine ether, made gratifying. Hexabromocyclododecane heat not affect its using effect in the process of flame retardant products processing, foreign entry type heat resistant hexabromocyclododecane in general the structure of the polymer processing temperature can keep not disorderly, and once the combustion does not produce too much smoke, this is our country hexabromocyclododecane to improvement.
