1. Flame Retardants, Functional Auxiliaries That Impart Flame Retardant Properties To Flammable Polymers, Are Primarily Designed For The Flame Retardant Design Of Polymeric Materials; Flame Retardants Are Available In A Variety Of Types And Are Classified As Additive Flame Retardants According To The Method Of Use. And Reactive Flame Retardants. Additive Flame Retardant Is Added To The Polymer By Mechanical Mixing Method To Make The Polymer Flame Retardant. Currently, The Additive Flame Retardant Mainly Includes Organic Flame Retardant, Inorganic Flame Retardant And Halogen Flame Retardant (Organic) Chlorides And Organic Bromides) And Non-Halogenated. Organic Flame Retardants Are Represented By Bromine, Phosphorus Nitrogen, Nitrogen And Red Phosphorus And Compounds. Inorganics Are Mainly Flame Retardant Systems Such As Antimony Trioxide, Magnesium Hydroxide, Aluminum Hydroxide, And Silicon. Reactive Flame Retardant Is Used As A Monomer To Participate In The Polymerization Reaction, So That The Polymer Itself Contains Flame-Retardant Components, Its Advantages Are Less Impact On The Use Of Polymer Materials, Flame-Retardant Long-Lasting.
There Are Many Substances That Can Be Used As Flame Retardants, Such As Alkyl Phosphates: Tributyl Phosphate, Tri(2-Ethylhexyl) Phosphate, Tris(2-Chloroethyl) Phosphate, Tris(2,3) -Dichloropropyl) Ester, Tris(2,3-Dibromopropyl) Phosphate, Pyrol99, Etc.; Aryl Phosphate: Toluene-Diphenyl Phosphate, Tricresyl Phosphate, Triphenyl Phosphate, Phosphoric Acid (2 -Ethylhexyl)-Diphenyl Ester And The Like. Dicyclopentadienes: Chloralanhydride, Etc. Aliphatic Halogenated Hydrocarbons, Especially Bromides: Aromatic Bromides Such As Dibromomethane, Trichloromethane, Dichlorobromomethane And Octabromodiphenyl Oxide, Pentabromoethylbenzene, Tetrabromobisphenol A, And Other Halogenated Compounds. . In Addition, There Are Tris(Dibromopropyl) Phosphate And Cyclohalohexane And Its Derivatives, Decabromodiphenyl Ether And Its Derivatives. Inorganic Flame Retardants Include Antimony Compounds, Hydroxy Aluminum, Magnesium Hydroxide, Borate, And The Like. Organic Nitrogen-Based Flame Retardants Such As Triazine And Its Derivatives, Melamine, Etc. Are Not Satisfactory When Used Alone, But When Used In Combination With A Phosphorus-Based Flame Retardant, They Can Play A Synergistic Effect. There Are Two Types Of Composite Flame Retardants Like This: One Is A Compound Flame Retardant With Mechanical Blending Of Two Flame Retardants; The Other Is A Compound Containing Both Nitrogen And Phosphorus. The Former Include Flame Retardants Composed Of Melamine And Polyphosphate Esters, Flame Retardants Composed Of Urea, Dicyandiamide And Phosphate Ester; The Latter Include Melamine Salt Of Pentaerythritol Phosphate Ester, Cyclophosphamide Polymer And The Like.

 

2. Plasticizers Are A Kind Of Macromolecular Material Auxiliaries, And They Are Also A Variety Of Phthalates (PAEs Phthalates) In Environmental Estrogens. The Most Common Species Is DEHP (Commercial Name DOP). The DEHP Chemical Name Di(2-Ethylhexyl) Phthalate Is A Colorless, Odorless Liquid That Is Widely Used In Industry.Plasticizers Are Also Generally Called Plasticizers. Plasticizers Are Industrially Widely Used Additives For Polymer Materials. Adding This Material To Plastics Processing Can Increase Its Flexibility, Ease Processing, And Can Be Legally Used In Industrial Applications. Taiwanese Manufacturers In China Used A Common Plasticizer, DEHP (After Successive Detection Of DINP, DNOP, DBP, DMP, DEP, Etc.) Instead Of Palm Oil To Produce Thickeners Similar To Emulsifiers. However, People In The Industry Pointed Out That DEHP, DINP And Other Plasticizers Do Not Belong To Food Spices. Therefore, DEHP Can Not Only Be Added To Food, And Even Not Allowed To Use In Food Packaging. "Clouding Agent" Is A Legal Food Additive, Often Used In Juices, Jams, Beverages And Other Foods. It Is Made From A Mixture Of Gum Arabic, Emulsifiers, Palm Oil And Various Food Additives.
