Polyurethane Liners | Wear Urethane Linings | Abrasion PU Liner & PU Lining

Polyurethane Liner Is a General Term For Polymers With Amino Ester Binding Groups. It Is Formed By The Combination Of Isocyanate Groups And Compounds With Active Hydrogen Such As Hydroxyl Groups. Polyurethane Lining Has Not Only The Elasticity Of Rubber, But Also The Strength And Excellent Processing Properties Of Plastics.

It Has Incomparable Advantages In Heat Insulation, Sound Insulation, Wear Resistance, Oil Resistance And Elasticity. It Is The Sixth Largest Plastic After Polyethylene, Polyvinyl Chloride, Polypropylene, Polystyrene And Abs. It Has Been Widely Used In Defense, Aerospace, Light Industry, Chemical Industry, Petroleum, Textile, Transportation, Automobile, Medical And Other Fields.

Wear Polyurethane Liner Resin Is a Kind Of Polymer With Repeated Structural Unit Of Carbamate Chain By Reaction Of Isocyanate With Polyol. Urethane Liner Products Can Be Divided Into Two Categories: Foam Products And Non-Foam Products, While Foam Products Are Divided Into Soft, Hard And Semi-Rigid, While Non-Foam Products Include Coatings, Adhesives, Elastomers And Elastic Fibers (Spandex). Polyurethane Material Has Excellent Properties And Wide Application, And Its Various Products Can Be Used In Many Fields.
1. Polyurethane Lining Foam Plastics
Urethane Linings Foam Has The Characteristics Of Light Weight, Good Resilience And Durability, Adjustable Density And Hardness, Good Impact Resistance, Good Thermal Insulation, And At The Same Time, It Has The Properties Of Easy Cutting, Perforation, Bonding And Processing.

Soft Polyurethane Foam Liner Plastic, Referred To As Polyurethane Soft Foam, Is a Kind Of Flexible With Certain Elasticity Pu Liner Foam Polyurethane Soft Foam Is The Largest Amount Of Polyurethane Products In Pu Lining Products. Polyurethane Soft Foam Is Mostly Open-Hole Structure, With Low Density, Good Elastic Recovery, Sound Absorption, Air Permeability, Heat Preservation And Other Properties, Mainly Used As Furniture Cushion, Mattress, Vehicle Seat Cushion And Other Cushion Materials, Industrial And Civil Use Of Soft Foam As Filter Materials, Sound Insulation Materials, Shockproof Materials, Decorative Materials, Packaging Materials And Heat Insulation Materials.

According To The Degree Of Soft And Hard, That Is, The Resistance To Load, Polyurethane Soft Foam Can Be Divided Into Ordinary Soft Foam, Super Soft Foam, High Bearing Soft Foam, High Rebound Soft Foam And So On, Among Which High Rebound Soft Foam, High Bearing Soft Foam Are Generally Used To Make Seat Cushion, Mattress. According To The Different Production Process, Polyurethane Soft Foam Can Be Divided Into Block Soft Foam And Molding Soft Foam, Block Soft Foam Is Through The Continuous Process To Produce Large Volume Foam And Then Cut Into The Desired Shape Of Foam Products, Molding Soft Foam Is Through The Gap Process Directly Mixed Raw Materials Into The Mold Foaming Into The Desired Shape Of Foam Products.

The Main Uses Of Polyurethane Soft Foam Include: Cushion Material, Such As Seat, Sofa, Mattress, Etc. Polyurethane Is a Very Ideal Cushion Material, Which Is Also The Application Field With The Largest Amount Of Soft Foam; Sound Absorption Material; Fabric Composite Material; Toys, Etc.

Hard Polyurethane Liner Foam, Referred To As Polyurethane Hard Foam, In Polyurethane Products In The Amount Of The Second Only To Polyurethane Soft Foam. Polyurethane Hard Foam Is Mostly Closed Hole Structure, With Good Insulation Effect, Light Weight, Large Specific Strength, Convenient Construction And Other Excellent Characteristics, But Also With Sound Insulation, Shockproof, Electrical Insulation, Heat Resistance, Cold Resistance, Solvent Resistance And Other Characteristics, Widely Used In Refrigerators, Freezers Box Insulation, Cold Storage, Refrigerated Trucks And Other Insulation Materials, Buildings, Storage Tanks And Pipes Insulation Materials, a Small Number Of Non-Adiabatic Occasions, Such As Imitation Wood, Packaging Materials.

In General, The Lower Density Polyurethane Hard Foam Is Mainly Used As Heat Insulation (Insulation) Material, And The Higher Density Polyurethane Hard Foam Can Be Used As Structural Material (Imitation Wood). The Main Uses Of Polyurethane Hard Foam Are: Food And Other Industries Frozen Refrigeration Equipment, Such As Refrigerators, Freezers, Cold Storage, Refrigerated Trucks And Other Refrigerated Equipment; Industrial Equipment Insulation, Such As Storage Tanks, Pipe Insulation; Building Materials; Transportation; Imitation Wood; Filling Materials, And So On.

2. Non-Foam Polyurethane Liner Products

The Application Range Of Non-Foam Products Varies According To The Type Of Products.Polyurethane Liner Coatings Are Based On Polyurethane Liner Resin, With Pigments, Fillers And Other Auxiliary Materials. In Polyurethane Liner Coatings, In Addition To Containing a Large Number Of Amino Ester Bonds, There Are Urea Bonds, Ester Bonds, Ether Bonds, Amide Bonds And So On.

These Special Bond Structures Endow The Coating With Excellent Adhesion, Wear Resistance, Flexibility, Resilience, Chemical Corrosion Resistance, Solvent Resistance, Luster, So As To Integrate Decoration And Protection.Polyurethane Liner Coatings Have a Wide Range Of Applications, Including The Following Aspects: Surface Coating Of Aircraft, Ships, Vehicles; Surface Coating Of Wood, Plastics, Rubber, Leather; Building Coating; Anticorrosive Coating, And Some Other Surface Coating With Higher Requirements.

Wear Polyurethane Liner Elastomer, Also Known As Polyurethane Liner Rubber, Is An Elastomer Polymer Material Containing More Isocyanate Groups In The Molecular Chain, And Its Structural Characteristics Make It Have Excellent Wear Resistance, Which Is Known As "Wear-Resistant Rubber ".Compared With Metal Materials, Polyurethane Liner Elastomer Has The Advantages Of Light Weight, Low Noise, Wear Resistance, Low Processing Cost And Corrosion Resistance; Compared With Plastics.

It Has The Advantages Of Non-Brittle, Elastic Memory And Wear Resistance; Compared With Rubber, It Has The Advantages Of Wear Resistance, Tear Resistance, High Bearing Capacity, Transparent Or Translucent, Ozone Resistance, Filling, Pouring, Wide Range Of Hardness And So On. Polyurethane Liner Elastomer Has Very Good Comprehensive Properties, So It Is Widely Used In Industry, Agriculture, Medical Treatment, National Defense And So On: Applications In Mining, Metallurgy And Other Industries —— Sieve Plates, Shakers, Etc.; Applications In Mechanical Industry —— Cots, Tape, Seals, Etc.; Applications In Automotive Industry —— Tires, Seals, Etc.: Applications In Light Industry ——Polyurethane Liner Sole Materials, Polyurethane Liner Synthetic Leather, Fiber, Etc.; Applications In Construction Industry —— Waterproof, Paving Materials, Filling Materials, Etc.

Wear Polyurethane Liner Adhesives Are Those Containing Amino Esters (- Nhcoo-) And/Or Isocyanates (- Nco-) In Molecular Chains. Polyurethane Liner Adhesives Have The Following Characteristics Compared With Other Adhesives: Polyurethane Liner Adhesives Contain Strong Polar And Chemically Active - Nco-、-Nhcoo- Groups, And Substrates Containing Active Hydrogen, Such As Foam, Plastics, Wood, Leather, Fabrics, Paper, Ceramics And Other Porous Materials, As Well As Metal, Glass, Rubber, Plastics And Other Smooth Surface Materials Have Excellent Chemical Adhesion; Polyurethane Liner Adhesives Have Excellent Shear Strength And Impact Resistance, Suitable For Various Structural Fields And Excellent Flexibility; Polyurethane Liner Adhesive Has Excellent Rubber Characteristics And Can Adapt To The Adhesion Of Different Thermal Expansion Coefficient Substrate, It Is Soft In The Formation Of Substrate. Hard Transition Layer, Not Only Strong Adhesion, But Also Excellent Buffer, Shock Absorption Function; Polyurethane Liner Adhesive Low Temperature And Ultra-Low Temperature Performance Over All Other Types Of Adhesive; In High Temperature, High Humidity Environment, Easy To Hydrolyze And Reduce The Bonding Strength.
