Engineering Bar Polyurethane Sticks PU Plastic Rod

I. Product Overview

II. Product Characteristics

(I) Chemical Properties

1. Chemical Resistance
   It has good tolerance to a variety of chemical substances, including but not limited to common organic solvents (such as alcohols, esters, ethers, etc.), weak acid and weak base solutions. When in contact with these chemical substances, PU Sheet will not undergo reactions such as dissolution, swelling, or embrittlement, thus ensuring its long-term stable performance in complex chemical environments. This enables it to be safely and reliably used in industries such as chemical engineering and electronics.
2. Anti-aging Properties
   The product contains special anti-aging additives that can effectively resist the effects of environmental factors such as ultraviolet radiation and oxidation. Even after long-term exposure outdoors or in harsh environmental conditions, the performance of PU Sheet can still remain stable, prolonging the service life of the product. This anti-aging characteristic makes it widely applicable in fields such as outdoor architecture and automotive components.

(II) Mechanical Properties

1. High Strength and Wear Resistance
   PU Sheet has excellent tensile strength, tear strength, and wear resistance. Its unique molecular structure endows the material with good load-bearing capacity, and it is not prone to cracking or wearing when subjected to external forces such as stretching, shearing, or friction. In applications with high loads and frequent friction, such as conveyor belts, shoe soles, and mechanical seals, it can maintain good performance, reducing the frequency of maintenance and replacement and improving production efficiency.
2. Good Elastic Recovery Ability
   Even after undergoing significant deformation, PU Sheet can quickly return to its original shape. This elastic recovery characteristic makes it outstanding in applications that require repeated compression or stretching, such as in cushion pads and spring substitutes. It can effectively absorb and release energy, providing stable cushioning and supporting effects.

(III) Other Properties

1. Good Machinability
   It can be formed by various processing methods, such as cutting, stamping, thermoforming, and injection molding. This provides great convenience for customers during the production process, allowing for flexible processing according to different design requirements and product shapes to meet diverse market demands.
2. Excellent Surface Properties
   The surface of PU Sheet can be treated according to needs to achieve different surface effects, such as smooth, matte, or textured. A smooth surface helps reduce the friction coefficient, which is suitable for applications requiring low resistance; while a matte or textured surface can increase the friction force, improving the grip or anti-slip performance of the product in specific environments. In addition, the surface can also be treated for anti-static and antibacterial properties, expanding the application range of the product.

III. Application Fields

(I) Industrial Field

1. Conveyor Belts
   Due to its high strength, wear resistance, and chemical resistance, PU Sheet is widely used in the manufacturing of various industrial conveyor belts, such as those in the food processing, logistics transportation, and mining industries. It can effectively transport materials and reduce maintenance costs.
2. Mechanical Seals
   In mechanical devices, it is used as a sealing gasket, capable of withstanding the effects of high pressure, high temperature, and chemical media, effectively preventing liquid or gas leakage and ensuring the normal operation of mechanical equipment.
3. Shock Absorbing and Cushioning Pads
   During the installation of heavy machinery and precision instruments, it serves as a shock-absorbing and cushioning material, capable of absorbing and dispersing the vibration and impact forces generated during the operation of the equipment, protecting the equipment from damage and improving the stability and service life of the equipment.

(II) Medical Field

1. Medical Mattresses and Cushions
   PU Sheet with low hardness, high elasticity, and good air permeability can be used to manufacture medical mattresses and cushions, providing comfortable support for patients, reducing the pressure on pressure points, and preventing the occurrence of bedsores. At the same time, the chemical resistance and easy-to-clean properties of the material also meet the hygiene requirements of the medical environment.
2. Medical Instrument Accessories
   For example, the handles of surgical instruments and the linings of stretchers, the soft touch, good grip performance, and easy-to-disinfect characteristics of PU Sheet make it an ideal material for medical instrument accessories.

(III) Household Field

1. Furniture Cushions and Backrests
   In household furniture, PU Sheet can be used to make sofa cushions, chair backrests, etc., providing a comfortable sitting feeling and good elastic recovery ability, and not being prone to deformation after long-term use. Its multiple colors and surface treatment methods can also meet the different decoration style requirements of households.
2. Floor Mats and Anti-slip Mats
   PU Sheet with anti-slip properties obtained through surface treatment can be made into floor mats and placed in areas prone to slipping such as bathrooms and kitchens, effectively preventing accidental slipping accidents. At the same time, its wear resistance and easy-to-clean properties also make the floor mats easy to maintain.

(IV) Electronic Field

1. Electronic Device Spacers
   During the assembly of electronic devices, PU Sheet, as a spacer material, can provide good cushioning and insulating properties, preventing electronic components from being affected by mechanical shock and electrostatic interference, ensuring the stable operation of electronic devices.
2. Keyboard Keys and Mouse Pads
   The soft touch and good elasticity of PU Sheet make it a high-quality material for manufacturing keyboard keys and mouse pads, which can improve the operation comfort of users and the performance of the devices.
