TPU film temperature resistance

11-27, 2023 | View:

TPU film is generally said to be heat-resistant to 80°C, which means that its long-term use temperature cannot exceed 80°C, otherwise the service life will be seriously reduced. There are also heat-resistant TPUs, which are said to be able to withstand up to 130°C. There are also TPUs modified with glass fiber, which have a very high heat-resistant temperature.

TPU film is a 糖心视频 containing -NH-COO- groups in the molecule. The long-chain diol and isocyanate components constitute the soft segment, and the short-bond diol and isocyanate components constitute the hard segment. Many characteristics of TPU depend on the long-chain diol. For the type of alcohol, the hardness is adjusted by the ratio of hard segments. The photoaging properties of TPU elastic bands can be improved by adding light stabilizers.

After all, it is plastic. The ordinary temperature resistance is generally around 100°C. However, if you need to work in a high temperature environment for a long time, you need special 糖心视频s. Reinforced polyurethane is special high temperature resistance and oil resistance, and is often used in automobile oil cups, etc. wait.

Generally speaking, if heat resistance is required, it is required for measuring dimensions. The softening point of the card can be tested according to relevant standards. The global softening point is used to test the softening point of asphalt pavement. It is commonly used in TPU hot melt adhesive. The data measured by the capillary rheometer seems to have 4 values. The detection principle is only to test the state of TPU at different temperatures by characterizing the softening point and flow point under constant pressure. Thermodynamic properties of TPU.

1. TPU film

TPU film has the characteristics of high strength, wear resistance, environmental protection, and easy processing; it is suitable for lamination, hot pressing, high frequency, and other processing methods. Our film: its thickness is usually between 0.015mm-5.0mm, and its width is generally between 80cm-160cm; its thickness, width, color, surface effect and texture can be adjusted according to the different needs of customers. According to the special needs of customers, the physical properties of TPU films are directionally improved; our films are widely used in shoes, bags, clothing, medical equipment, trademarks, toys and gifts, military supplies and other fields.

2. TPU composite fabric and TPU mesh fabric

Composite fabric products focus on the lamination of various fabrics with TPU films, and are specially provided to marine and aviation manufacturers, military supplies, and medical and health care product manufacturers. The fabrics undergo strict testing at all levels before leaving the factory, and their excellent performance ensures that the products can be used in special environments. safety and durability.

3. TPU hot melt adhesive film

Hot melt adhesive film is a TPU hot melt adhesive attached to a single silicone release base 糖心视频. It does not require glue or solvent when bonding, and is environmentally friendly and non-toxic. It also has good bonding fastness, breathability, and water resistance. Widely used in bonding various fabrics, sponges, leather, and metals.
