PU Sheet 1-2

I. Product Overview

II. Product Characteristics

(I) Physical Characteristics

1. Flexibility
   PU Sheet has excellent flexibility and can maintain its integrity under different bending and stretching conditions without breaking or cracking easily. This enables it to adapt to complex-shaped application environments, such as performing well in packaging or decoration applications that require fitting curved surfaces.
2. Strength
   Despite being soft, it still possesses a certain degree of strength and can withstand a certain amount of pressure and tension. Its tensile strength and tear strength can be adjusted according to different formulations and production processes to meet the needs of different application scenarios. For example, in the application of cushion pads that bear the weight of heavy objects, it can effectively disperse the pressure.
3. Diversity in Thickness and Size
   It can be produced in various thickness specifications, ranging from extremely thin millimeter levels (such as the ultra-thin PU Sheet used for packaging precision electronic components) to thicker sheets (used in large application scenarios such as industrial shock absorption and sound insulation). Meanwhile, the size can also be customized according to customer requirements. Large-sized sheets can meet the need for covering large areas, such as in the application of building sound insulation.

(II) Chemical Characteristics

1. Chemical Resistance
   PU Sheet has good tolerance to many chemical substances. It can resist the erosion of common organic solvents, oils, and some mild acid-base solutions. It is widely used in industrial scenarios with complex chemical environments, such as sealing gaskets for chemical pipelines and linings for chemical storage containers.
2. Stability
   Under normal temperature and humidity conditions, PU Sheet has good chemical stability and is not prone to decomposition, aging, or deterioration. Within a certain temperature range (usually from -40°C to 80°C), it can maintain its performance stability, making it suitable for various applications under different climatic conditions.

(III) Other Characteristics

1. Comfort (for Applications in Contact with the Human Body)
   If used to make insoles, seat cushions, and other products that come into direct contact with the human body, PU Sheet has a soft and comfortable touch and good air permeability, which can reduce stuffiness and moisture accumulation and improve the comfort of users.
2. Sound Insulation and Heat Insulation
   The porous structure inside PU Sheet endows it with certain sound insulation and heat insulation properties. In the field of architecture, it can be used as a heat insulation and sound insulation material for walls, roofs, etc., effectively reducing external noise interference and heat transfer and improving the comfort of the indoor environment.
3. Cushioning Performance
   It has excellent cushioning performance and can effectively absorb and disperse impact forces. In the packaging field, it is used to protect fragile items such as glass products and precision instruments from damage caused by vibration and collision during transportation; in sports protective equipment such as helmet linings and knee pads, it can reduce sports injuries.

Application Areas of the Product

(I) Industrial Field

1. Sealing Gaskets
   In pipe connections and sealing parts of mechanical equipment, PU Sheet can be used as sealing gaskets. Its good flexibility and chemical resistance can effectively prevent the leakage of liquids and gases, ensuring the sealing and stability of the system.
2. Shock Absorption and Cushioning Materials
   In industrial automation production lines and the installation of precision instrument equipment, it is used as a shock-absorbing pad to reduce the vibration and noise generated during the operation of the equipment, protect the equipment from vibration damage, and extend the service life of the equipment.
3. Conveyor Belts
   In some light-duty material conveying systems, the conveyor belts made of PU Sheet have good flexibility and friction, can transport materials smoothly, and their wear resistance can also ensure the long-term use of the conveyor belts.

(II) Packaging Field

1. Packaging of Electronic Components
   The ultra-thin and soft PU Sheet can be used to package precision electronic components such as electronic chips and integrated circuits, providing cushioning protection to prevent them from being damaged by static electricity, vibration, and collision during transportation and storage.
2. Packaging of Fragile Items
   For the packaging of fragile items such as glass products and ceramic products, PU Sheet can be customized, cut, and formed according to the shape of the items, used as a lining or wrapping material to effectively absorb external impact forces and reduce the risk of breakage.

(III) Architectural Field

1. Heat Insulation and Sound Insulation Materials
   It is used in the heat insulation and sound insulation layers of building walls, roofs, and floors, which can effectively reduce heat transfer and external noise interference. It can be combined with other building materials to improve the energy efficiency and living comfort of buildings.
2. Waterproof Sealing
   In building waterproof engineering, such as roof waterproofing and basement waterproofing, the water resistance and flexibility of PU Sheet can ensure the sealing effect and prevent water penetration.

(IV) Daily Life Field

1. Insoles and Shoe Materials
   The insoles made of PU Sheet have the characteristics of softness, comfort, air permeability, sweat absorption, and shock absorption, which can improve the wearing comfort of shoes. Meanwhile, in some fashion shoe styles, PU Sheet can also be used as a decorative material for the upper or a support material for the heel.
2. Furniture Decoration and Cushioning
   It is used for filling and decorating seat cushions, sofa cushions, etc. of furniture, providing a comfortable sitting feeling and a good appearance. In addition, in the movable parts such as drawers and cabinet doors of furniture, it can be used as a cushioning pad to reduce collision noise and wear.
3. Sports Goods
   It is widely used in sports protective equipment such as helmets, elbow pads, knee pads, and cushioning pads of fitness equipment. It can effectively absorb and disperse impact forces during sports and protect athletes from injuries.
