FILLER/ADDITIVES

Filler materials are particles added to resin or binders (plastics, composites, concrete) that can improve specific properties, make the product cheaper, or a mixture of both.

Acrylic

ACR Is Kind Of Polymer With Speacial Structure. ACR Resin Is Composed Of Methyl Methacrylate, Butyl Acrylate By Seed Emulsion Polymerization Is A Kind Of Thermoplastic Graft Polymer, And Has A Dual Function Of Impact Modification And Processing Of Plastic Additives, Mainly Used For Hard And Half Hard PVC Prouducts (I.e. Building Materials, Pipes, Pipe Fittings, Sheet, Foam Materials Etc.


Chlorinated Polyethylene (CPE)

Chlorinated Polyethylene Is An Inexpensive Variation Of Polyethylene Having A Chlorine Content From 34 To 44%. It Is Used In Blends With Polyvinyl Chloride Because The Soft, Rubbery Chlorinated Polyethylene Is Embedded In The PVC Matrix, Thereby Increasing The Impact Resistance. In Addition, It Also Increases The Weather Resistance. Furthermore, It Is Used For Softening PVC Foils, Without Risking Plasticizer Migration. Chlorinated Polyethylene Can Be Crosslinked Peroxidically To Form An Elastomer Which Is Used In Cable And Rubber Industry. When Chlorinated Polyethylene Is Added To Other Polyolefins, It Reduces The Flammability.

Calcium Carbonate

Calcium Carbonate Is Additives Used When Making Filler Masterbatch Or Compound. The Purpose Of This Action Is To Make Final Products Replace For Using 100% Primary Plastic.Making Plastic Pipe Or Some Construction Products As Films, Plastic Door, Ceiling Sheets Is Considered A Typical Example Of Using Caco3. It Increases Durability, Better Dispresion In Plastic Chemicals And Optimal Gloss Of Products.


Isocyanates

Isocyanates Are A Family Of Highly Reactive, Low Molecular Weight Chemicals. They Are Widely Used In The Manufacture Of Flexible And Rigid Foams, Fibers, Coatings Such As Paints And Varnishes, And Elastomers, And Are Increasingly Used In The Automobile Industry, Autobody Repair, And Building Insulation Materials. Spray-on Polyurethane Products Containing Isocyanates Have Been Developed For A Wide Range Of Retail, Commercial, And Industrial Uses To Protect Cement, Wood, Fiberglass, Steel And Aluminum, Including Protective Coatings For Truck Beds, Trailers, Boats, Foundations, And Decks.

Master Batches

Masterbatches Are Solid Or Liquid Additives For Plastic Or Imparting Other Properties To Plastics. Masterbatches Are A Concentrated Mixture Of Pigments And/or Additives Encapsulated During A Heat Process Into A Carrier Resin, Which Is Then Cooled And Cut Into A Granular Shape. Masterbatches Allows The Processor To Colour Raw Polymer Economically During The Plastics Manufacturing Process.


PVC Stabilizer

Polymer Stabilizers Are Chemical Additives Which May Be Added To Polymeric Materials, Such As Plastics, To Inhibit Or Retard Their Degradation.Stabilizers Are Used At All Stages Of The Polymer Life-cycle. They Allow Plastic Items To Be Produced Faster And With Fewer Defects, Extend Their Useful Lifespan, And Facilitate Their Recycling. However They Also Continue To Stabilise Waste Plastic, Causing It To Remain In The Environment For Longer. Many Different Types Of Plastic Exist And Each May Be Vulnerable To Several Types Of Degradation, Which Usually Results In Several Different Stabilisers Being Used In Combination. Even For Objects Made From The Same Type Of Plastic, Different Applications May Have Different Stabilisation Requirements. Regulatory Considerations, Such As Food Contact Approval Are Also Present. A Wide Range Of Stabilizers Exist Is Therefore Needed.

Polyol

Polyols Are The Main Reaction Partners Of Polyisocyanates And Their Chemical Composition And Molecular Mass Determine The Properties Of The Resulting Purs. About 75% Of All Polyols Are Polyether Polyols, And About 25% Are Polyesters And Other Polyols.polyether Polyols Are More Stable Against Hydrolysis, But Less Stable Against Oxidation Compared With Polyester Polyols. Therefore, Polyether Polyols Are Mostly Stabilized By Antioxidants. Polyester Polyols Are Generally More Viscous And Less Stable Against Hydrolysis, But The Resulting Purs Often Show Better Physical Properties.polyether Polyols Are Manufactured By The Addition Of Cyclic Ethers (EPOXIDES), Especially Ethylene Oxide (EO) Or Propylene Oxide (PO) To Dior Polyfunctional Starter Molecules (Figure 18): Catalysis Is Necessary For This Reaction. Classically, An Anionic Catalysis With Strong Bases Like Potassium Hydroxide (KOH) Was Used.
