Product Description Product DescriptionCore Definition: Polyurethane, with its English full name abbreviated as PU, is a polymer with a main chain that contains carbamate groups (-NHCOO-). In industry terms, MDI and TDI are polyurethane upstream raw materials (isocyanates), referring to diphenylmethane diisocyanate (MDI) and toluene diisocyanate (TDI), respectively.Polyurethane industrial accessories are customized functional components made from polyurethane (PU) materials. By adjusting the formula and process, they can achieve a performance range from elastomers to hard plastics, and are widely used in scenarios requiring wear resistance, shock absorption, and sealing.Classification of Polyurethane1. ElastomersCast elastomer (CPU): Offering a wide hardness range (Shore A 70-95), oil resistance, and low-temperature resistance, it is used for mine screen plates, sealing rings, etc.Thermoplastic elastomer (TPU): Over five times more resistant than conventional rubber, suitable for rubber rollers, soles, and medical catheters.2. FoamHard foam (PUF): With a thermal conductivity as low as 0.024 W/mK, it is utilized for building insulation and cold chain transportation heat insulation.3. Functional ProductsSeals: Featuring high-temperature resistance (up to 150oC) and hydrolysis resistance, they are used for automobile oil seals and engine seals.Rollers and conveying parts: Resistant to solvents and antistatic, suitable for printing, textiles, mining machinery, etc.Detailed PhotosProduct Parametersperformance indexTypical values / featuresapplication scenariosabrasion performanceAbrasion index 0.05 mg / cm2 (5 x super rubber)Mine screen plate, conveyor belt rollertemperature tolerance-70oC ~150oC (up to 300oC for some special materials)High-temperature sealing ring, automobile engine partschemical resistance Oil resistance, acid and alkali resistance, electrolyte resistance (such as new energy vehicle battery packaging)Chemical equipment sealing, battery cooling pipeShock absorption and return elasticityCompression deformation rate is 5%, and rebound rate is 60%Shock pad, cushion rubber head, car bumperPackaging & ShippingInstallation InstructionsTypical Application Areas1. Interior Parts: Polyurethane armrests and seat foam offer high resilience (with a laboratory-tested lifespan increased by threefold), and their lightweight design reduces the vehicle's energy consumption.2. Sealing and Shock Absorption: Sealing strips and shock-absorbing rubber cushions boast a weather resistance of 10 years, making them suitable for the high-pressure environments of new energy vehicles. Acid and alkali-resistant seals are utilized for chemical equipment, and self-repairing polyurethane extends the lifespan of components by 30%.3. New Energy Components: Battery packaging adhesives exhibit electrolyte corrosion resistance, with voltage resistance reaching up to 60MPa; TPU cable sheaths are used for high-voltage lines.4. Mine Equipment: The life expectancy of CPU screen plates is triple that of metal, and they are equipped with strong wear resistance for use in ball mills and crushers.5. Rollers and Transmission Wheels: Food-grade polyurethane rollers are solvent-resistant, with a surface roughness of Ra 0.1 μm, making them suitable for printing and textile machinery.6. Electronics and Semiconductors: Semiconductor CMP polishing pads are utilized in silicon wafer polishing, and thermal conductive polyurethane materials are used in medical CT slip rings.7. Suspension System: Polyurethane buffer blocks (Jounce Bumpers) and top mounts (Top Mounts) replace rubber components to enhance vehicle NVH performance (reducing noise, vibration, and harshness).8. Aerospace: High-temperature resistant polyurethane seals are utilized for engine compartment vibration isolation, and their lightweight design is tailored to fit rocket structures.9. Household appliances: Refrigerator compressor shock absorption pads reduce operating noise and enhance energy efficiency. Polyurethane Core Characteristics1. High elasticity and resilience energyThe polyurethane elastomer can undergo significant deformation under pressure (up to a 75% deflection rate is permissible), and it can absorb impact energy through its internal microporous structure, thereby reducing the impact force.With a compression deformation rate of 5% and a recovery rate of 60%, it can quickly restore from deformation, making it suitable for high-frequency vibration scenarios.2. Wear resistance and tear resistanceThe abrasion index is 0.05 mg/cm2, and the wear resistance is over five times that of rubber, extending the lifespan of mining equipment by three times compared to metal parts.It possesses high tear resistance strength, capable of withstanding wear from sharp objects or complex working conditions.3. Environmental adaptabilityTemperature resistance range spans from -20oC to 150oC; special modified materials can endure extreme temperatures up to 300oC.It is oil-resistant, resistant to acids and alkalis, and electrolyte corrosion, making it suitable for chemical equipment and the high-pressure environments of new energy vehicles.
