Advantages of TPU adhesive film

Wear-resistant and scratch-resistant

TPU film has extremely high wear resistance and scratch resistance, and can effectively resist friction and scratches in daily use, keeping the seat cushion smooth and beautiful. This feature allows the TPU film cushion to maintain good appearance and performance during long-term use, extending its service life.

High elasticity and fit

TPU film has extremely high elasticity and can fit perfectly with various complex shapes and curves of car seats, allowing for seamless installation.

This high elasticity also provides good cushioning of the seat, reducing noise and damage caused by vibration or impact.

UV protection and weather resistance

Due to its powerful UV blocking ability, the TPU film can effectively reduce the impact of UV rays on the seat cushion materials and maintain the brightness of the seat cushion color and the stability of the material.

At the same time, TPU film also has good weather resistance and can maintain its performance and extend its service life in a variety of harsh environments.

Insulation and comfort

Due to its excellent heat resistance and thermal insulation properties, the TPU film effectively insulates the surface of the seat from direct contact with a high-temperature environment, reduces the seat temperature and increases the comfort of the driver and passengers.

This feature is especially important at high temperatures in summer, as it can provide drivers and passengers with more comfortable driving conditions.

Extrusion method

In this process, the TPU raw material is fed into the extruder cylinder, where it is heated and melted. The molten material is extruded into a TPU sheet film, which is then trimmed, cooled and packaged.

Blow Molding

Blow molding includes making the TPU extruded film a tubular shape using an annular gap shape. Compressed air is fed through the core rod, inflating the TPU film to the desired outer diameter. Then the film is cooled, molded and wound on rolls.

Calendering

Calendering uses several heated rollers that rotate next to each other to continuously form a TPU film. The thickness of the film is adjustable by adjusting the gap between the final rollers. This method is widely used for precise thickness control.

Casting method

This process involves melting, filtration, and degassing of TPU raw materials before being fed into the casting machine. The molten TPU is distributed as a film of the desired thickness through the mold.

Stretching method

The stretching involves extending the TPU film at temperatures between the softening and melting points. This can be done in both unidirectional and bidirectional ways. However, bidirectional stretching is preferred in most industrial applications as it improves the performance and mechanical properties of TPU films.
