2. Construction Industry: Ensuring Durability and Sustainability
In the construction industry, TPE extrusion materials play an important role in improving the quality and durability of buildings, while also aligning with the trend of sustainable construction.
- Building Sealing and Gasketing: Similar to their use in the automotive industry, TPE extrusion materials are used to produce various sealing products for buildings, such as window seals, curtain wall gaskets, and expansion joints. These extruded seals have strong resistance to UV radiation, ozone, and moisture, preventing water leakage and air infiltration in buildings. For instance, the window seals made of TPE extrusion materials can maintain their elasticity and sealing performance for more than 10 years, reducing the maintenance costs of buildings.
- Pipe and Tubing Systems: TPE extrusion materials are used to manufacture pipes and tubes for plumbing and heating systems in buildings. The extruded TPE pipes have good flexibility, making them easy to install in complex building structures. They also have excellent chemical resistance, resisting corrosion from various liquids such as water and cleaning agents. Moreover, TPE is recyclable, which helps reduce construction waste and promotes sustainable development in the construction industry.
- Floor and Wall Trims: Extruded TPE profiles are used as floor trims and wall trims in buildings. These trims can protect the edges of floors and walls from damage, while also covering gaps and improving the aesthetic appearance of the building interior. The soft and flexible nature of TPE makes the trims easy to install and fit different shapes of floor and wall edges.
3. Electrical and Electronics Industry: Guaranteeing Safety and Reliability
The electrical and electronics industry requires materials with high electrical insulation, heat resistance, and mechanical strength, and TPE extrusion materials meet these requirements, making them widely used in this field.
- Wire and Cable Jackets: TPE extrusion materials are commonly used to produce jackets for electrical wires and cables. The extruded TPE jackets have excellent electrical insulation properties, preventing electrical leakage and ensuring the safety of electrical equipment. They also have good heat resistance, able to withstand the heat generated during the operation of electrical equipment without deforming or melting. In addition, TPE jackets have good flexibility, making the wires and cables easy to bend and install in narrow spaces.
- Connector Seals and Gaskets: In electrical connectors, TPE extrusion materials are used to make seals and gaskets. These extruded components can effectively prevent dust, moisture, and other contaminants from entering the connectors, ensuring the reliable connection of electrical signals. The chemical resistance of TPE also allows the seals and gaskets to resist corrosion from various chemicals in the working environment, extending the service life of the connectors.
- Electronic Device Casings and Accessories: Extruded TPE profiles are used in the casings and accessories of electronic devices such as smartphones, tablets, and laptops. For example, the edge protectors of tablet casings made of TPE extrusion materials can absorb impact energy, protecting the tablet from damage when dropped. TPE also has a good feel, improving the user experience of electronic devices.
4. Medical Industry: Meeting Strict Hygiene and Biocompatibility Standards
The medical industry has extremely high requirements for materials, especially in terms of hygiene, biocompatibility, and sterilization resistance. TPE extrusion materials, with their excellent properties, have become an important material in medical device manufacturing.
- Medical Tubing: TPE extrusion materials are widely used to produce medical tubing, such as infusion tubes, catheters, and respiratory tubes. The extruded TPE medical tubing has a smooth inner surface, which reduces the resistance to the flow of liquids or gases and prevents the accumulation of bacteria. TPE is also biocompatible, meaning it does not cause an allergic reaction or other adverse effects when in contact with human tissues or body fluids. Additionally, TPE medical tubing can be sterilized using various methods such as autoclaving, ethylene oxide sterilization, and gamma radiation sterilization, ensuring the hygiene and safety of medical devices.
- Seals for Medical Equipment: In medical equipment such as sterilizers, incubators, and diagnostic instruments, TPE extrusion materials are used to make seals. These extruded seals have good airtightness and water tightness, ensuring the normal operation of medical equipment. They also have excellent resistance to high temperatures and chemicals, able to withstand the harsh conditions of sterilization and cleaning processes.
- Medical Device Grips and Handles: Extruded TPE profiles are used as grips and handles for medical devices such as surgical instruments and wheelchairs. The soft and non - slip surface of TPE provides a comfortable grip for medical staff, reducing hand fatigue during long - term use. TPE is also easy to clean and disinfect, complying with the hygiene standards of the medical industry.
5. Consumer Goods Industry: Improving Product Quality and User Experience
In the consumer goods industry, TPE extrusion materials are used in a wide range of products to enhance their quality, functionality, and user experience.
- Household Appliance Components: TPE extrusion materials are used to produce components for household appliances such as washing machine door seals, refrigerator door gaskets, and air conditioner duct seals. These extruded components have good sealing performance, ensuring the efficient operation of household appliances. For example, the washing machine door seal made of TPE extrusion materials can prevent water leakage during the washing process, while also resisting the corrosion of detergent and high temperatures.
- Toy Manufacturing: TPE extrusion materials are used in the production of toys, such as toy car tires, doll arms and legs, and building block edges. TPE is non - toxic and soft, making it safe for children to play with. The extruded TPE toy components have good elasticity and durability, able to withstand repeated bending and impact without breaking.
