Product Description
Definition
Ultra-high molecular weight polyethylene (UHMWPE) felt is a felt-like material mainly made from ultra-high molecular weight polyethylene (UHMWPE) fibers. Ultra-high molecular weight polyethylene is a type of polyethylene with an extremely high molecular weight (usually with a molecular weight of over 1.5 million). These fibers possess numerous outstanding properties, and through special processes, they are processed into a felt-like structure, thus forming the ultra-high molecular weight polyethylene felt.
Manufacturing Process
- Fiber Preparation: Firstly, ultra-high molecular weight polyethylene resin is synthesized through a polymerization reaction, and then it is made into fibers by adopting special spinning processes. These fibers usually have a very fine diameter and possess high strength and flexibility.
- Felt-forming Process: Generally, ultra-high molecular weight polyethylene fibers are subjected to processes such as carding and laying to make the fibers evenly distributed and form a fiber web. Subsequently, methods like needling, thermal bonding or chemical bonding are used to reinforce the fiber web into a felt-like structure. For example, in the needling process, needles with barbs are used to repeatedly pierce the fiber web, causing the fibers to interlace with each other, thereby enhancing the strength and stability of the felt.
Performance Characteristics
- Ultra-high Strength: The strength of ultra-high molecular weight polyethylene felt is extremely high, and its tensile strength is much higher than that of felts made from ordinary fibers. This is because ultra-high molecular weight polyethylene fibers themselves have high strength, and during the process of making the felt, the interaction among the fibers further enhances the overall strength. Such high strength enables it to withstand relatively large tensile and compressive forces and is widely used in fields where high-strength materials are required.
- Good Abrasion Resistance: This felt has excellent abrasion resistance and can maintain its structural integrity and stable performance for a long time in a frictional environment. Whether in dry friction or in the presence of lubricants, its abrasion resistance performance is remarkable, which is due to the molecular chain structure of ultra-high molecular weight polyethylene fibers and the close arrangement among the fibers. For example, in application scenarios such as conveyor belts, it can effectively reduce wear and prolong the service life.
- Chemical Corrosion Resistance: It has good tolerance to most chemical substances, including acids, alkalis and organic solvents. This enables it to be used in corrosive environments such as the chemical industry without being easily eroded and damaged by chemical substances.
- Low Density and Light Weight: Ultra-high molecular weight polyethylene felt has a relatively low density and is lightweight. This characteristic gives it an advantage in some applications with weight requirements, such as in the aerospace or sports equipment fields, where it can reduce weight while ensuring strength.
- Excellent Impact Resistance: It can effectively absorb and disperse impact energy and has good impact resistance. When subjected to external impact, the interaction among the fibers and the structure of the felt can buffer the impact force and reduce damage.
Application Fields
- Industrial Field: In industry, it can be used as conveyor belts, filtering materials, cushioning materials, etc. As a conveyor belt, it can carry relatively heavy goods and is wear-resistant; as a filtering material, it can effectively filter impurities, and due to its chemical corrosion resistance, it can adapt to multiple chemical environments; as a cushioning material, it is used for product protection during packaging and transportation.
- Protective Field: It is used to make protective clothing, protective gloves and other protective equipment. Its high strength and impact resistance can protect the human body from mechanical injuries, and its chemical corrosion resistance can also resist the harm of chemical substances to the human body.
- Sports Field: It is used to manufacture sports equipment, such as ski boards, surfboards, etc., taking advantage of its lightweight and high-strength characteristics to improve the performance of the equipment and reduce the burden on athletes at the same time.
