Stabilizers Purpose And Effect Of Introduction.Triphenyl Phosphite (TPPI)

     (1) Lead Compounds Lead Compounds Include Sulfuric Acid, Carbonic Acid, Phosphoric Acid, Phthalic Acid, Stearic Acid Lead Salts. Lead Stabilizers Are Used To Stabilize The Earliest Varieties Of PVC, Thermal Stability Works Well, Some Lead Salt Also Has Good Light Stability. With This Stabilizer Can Not Be Obtained Clear And Transparent Film, In The Presence Of Hydrogen Sulfide Film Will Appear Dark Brown. For These Reasons, It Can Not Be Used In All The Films.Stabilizers Purpose And Effect Of Introduction.Triphenyl Phosphite (TPPI)


     (2) Barium Soaps And Soap Barium Cadmium And Cadmium (Also Including Calcium) Soaps Of Organic Acids (Such As Stearic Acid Soaps, Lauric Acid Soaps), Often Alone Or Mixed With Other Stabilizers As Polyvinyl Chloride Film (Especially Soft PVC Film) Heat, Light Stabilizers. Applications Barium Cadmium Soap And Soap Can Solve Many Of Manufacture And Application Of Technical Problems. Such As Proper Ratio, In Addition To The Effect Of Thermal Stability, It Will Also Produce A Satisfactory Light Stability.


Chelating Agents May Form A Complex With A Metal Chloride Generated, And Thus It Does Not Produce Harmful Effects. At Present, The Commonly Used Phosphite Chelators Have A Benzene Diisooctyl Vinegar, Triphenyl Phosphite. Is Currently Expanding A Liquid Barium Cadmium Applications, Adding A Lot Of Phosphite Chelators Terephthalic Isooctyl And A Small Amount Of Bisphenol A And Pentaerythritol In A Liquid Barium Cadmium. Such A Chelating Agent And Stabilizer Systems Liquid Stabilizer Composition, Commonly Used In Soft Films And Achieved Good Results.Stabilizers Purpose And Effect Of Introduction.Triphenyl Phosphite (TPPI)

      As We All Know, Barium And Cadmium Compounds Are Not Toxic. Calcium, Zinc Compounds Can Be Achieved Without The Stabilizing Effect On The Physiological Effects.


     (3) Tin Compounds Mamy Acid And Lauric Acid And Esters Of Diorganotin Dialkyltin Mercaptan Is The Most Expensive, But It Is Also Used For Hard Or Soft PVC In The Best Stabilizer. We Can Ensure Transparent Film Has The Best Transparency And Good Thermal Stability Effect, Mainly For The Production Of Suspension PVC Hard And Soft Transparent Film. At The Same Time Long-Chain Alkyl Tin Compound In A Stabilizing Effect Can Be Made To Ensure That The Rigid Film Used For Packaging Is Completely Non-Toxic.

1. As Synthetic Rubber And Resin Stabilizer, Antioxidant And Raw Materials PVC Alkyd Resin And Pesticide Intermediates. As The Cellulose Resin, Vinyl Resin, Natural Rubber And Synthetic Rubber Flame Retardant Plasticizer. This Product Is Of Low Volatility, High Flame Retardant Efficiency, With Excellent Mechanical Property Retention, Transparency, Flexibility And Toughness. Mainly Used For Nitrocellulose, Cellulose Acetate Film (E.G., Film Base) And A Flame-Retardant Plasticizer Plastic Film, Can Also Be Used In Viscose Fiber As Camphor Nonflammable Substitutes.

2. As Polyethylene, Polypropylene, Polyvinyl Chloride, ABS Resin, Epoxy Resin, Synthetic Rubber And Polyester Polymers Antioxidant Stabilizer. Halogen Flame Retardants And Use, Can Play Its Fire-Retardant And Antioxidant Effect, And Having A Light Stabilization. Also Widely Used In PVC Chelator, When A Metal Soap-Based Stabilizers, Together With The Product Can Reduce The Harm Of Metal Chlorides, And To Maintain The Transparency Of Products And Inhibit Change Chromaticity. It Can Also Be Used As A Synthetic Alkyd Resins, Polyesters, Phosphorous Acid Alkyl Esters.Stabilizers Purpose And Effect Of Introduction.Triphenyl Phosphite (TPPI)


     (4) Pure Organic Stabilizer In The Case Of A Small Amount (Almost 1% Lower), Pure Organic Emulsion Can Be Bit Hard And Soft Polyvinyl Chloride Resin Film Having Excellent Thermal Stability, But Not As Light Stabilizers Agents. Diphenyl Thiourea, Phenyl Indole And Aminocrotonate Is Pure Organic Stabilizers.


     (5) An Epoxy Compound As The Epoxy Compound Has A Stabilizing Effect Plasticization. Can Absorb Hydrogen Chloride, The Residue Can Be Well Compatible With PVC. In Soft PVC Film, The Maximum Amount Of Epoxy Plasticizers Up To About 20% Of The Total Intake Of Plasticizers. In Addition To Having Good Thermal Stability Effect, There Is A Good Light Stabilizing Effect, It Is Often Applied To Film Outdoor Use.
