When choosing the right TPE material, it’s important to understand the differences between various types of TPE. In this article, we will compare TPE 2317 VS TPE 2382, focusing on their differences in hardness, flexibility, temperature resistance, and applications. This comparison will help you select the most suitable TPE material for your needs.
TPE 2317 vs TPE 2382:Hardness and Flexibility
- TPE 2317:
- Hardness: TPE 2317 is relatively soft, with a Shore A hardness typically ranging from 20-40. This makes it ideal for applications that require a gentle, soft touch.
- Flexibility: Due to its softness, TPE 2317 is highly flexible and comfortable, making it perfect for items such as electronics covers, handles, and accessories.
- Elasticity: TPE 2317 offers good elasticity, quickly returning to its original shape after being stretched or compressed.
- TPE 2382:
- Hardness: TPE 2382 is harder, with a Shore A hardness between 50-70 or Shore D 30-40. This makes it more suitable for applications that require strength and durability.
- Rigidity and Strength: Compared to TPE 2317, TPE 2382 has higher rigidity and tensile strength, making it ideal for parts that need to endure mechanical stress.
- Elasticity: While less elastic than TPE 2317, TPE 2382 remains flexible enough for various uses.
TPE 2317 vs TPE 2382:Temperature Resistance and Chemical Resistance
- TPE 2317:
- Temperature Resistance: TPE 2317 works well in temperatures ranging from -20°C to 80°C. However, it is not suitable for high-temperature environments.
- Chemical Resistance: This material offers some resistance to common chemicals, but it may degrade when exposed to strong acids, bases, or solvents.
- TPE 2382:
- Temperature Resistance: TPE 2382 has a broader temperature range, typically from -40°C to 120°C. This makes it ideal for extreme temperature conditions, such as in automotive or industrial applications.
- Chemical Resistance: TPE 2382 shows superior resistance to oils, solvents, acids, and bases, making it perfect for harsh chemical environments.
TPE 2317 vs TPE 2382:UV Resistance and Aging Resistance
- TPE 2317:
- UV Resistance: TPE 2317 has limited UV resistance. Extended exposure to sunlight can cause aging, discoloration, or brittleness. It is better suited for indoor applications or environments with controlled exposure to UV.
- Aging Resistance: Compared to other TPE materials, TPE 2317 tends to age more quickly, especially in humid or fluctuating temperature conditions.
- TPE 2382:
- UV Resistance: TPE 2382 excels in UV resistance. It maintains stability and performance even with prolonged sunlight exposure, making it ideal for outdoor applications like automotive exterior parts.
- Aging Resistance: TPE 2382 performs better over time, resisting environmental stress and maintaining its properties for longer.
Applications
- TPE 2317:
- Electronics: Due to its soft and comfortable touch, TPE 2317 is widely used in mobile phone covers, remote controls, and other electronic product casings.
- Automotive Interiors: It is also used for car interior components like dashboards, door panels, and armrests.
- Medical Devices: TPE 2317 is suitable for medical applications such as tubing and soft contact parts in medical instruments.
- TPE 2382:
- Automotive Exteriors: TPE 2382 is ideal for automotive exterior parts, such as sealings, light covers, and trims, due to its higher strength, temperature resistance, and UV protection.
- Industrial Parts: Its durability makes it perfect for industrial applications like seals, gaskets, and machinery housings.
- Outdoor Equipment: Thanks to its excellent UV resistance, TPE 2382 is often used in outdoor products like furniture and sports equipment.
Processing
- TPE 2317:
- Ease of Processing: TPE 2317 is easy to process, whether by injection molding or extrusion. It offers good shape stability and precision, especially at lower temperatures.
- TPE 2382:
- Processing: TPE 2382 also processes well but may require higher temperatures or more advanced equipment due to its higher hardness. It is ideal for precise molding and high-performance mechanical applications.
