Our TPU Thermoplastic Polyurethane Thermal Bonding Film is specifically engineered for the assembly of automotive steering wheel heating elements. Unlike conventional adhesives, this film provides uniform heat distribution and exceptional bonding strength between the heating element and the leather/faux leather cover. It is activated during the hot-pressing process, creating a durable, flexible, and vibration-resistant bond that maintains integrity under extreme temperatures. This solution streamlines your lamination process for heated steering wheels while ensuring long-term reliability and a smooth, comfortable surface finish.

This is a type of hot melt adhesive film specially designed for use in automotive steering wheel heating modules. It is typically made from TPU (thermoplastic polyurethane) and is used to bond heating elements (e.g. wires or heating sheets) to the steering wheel interior materials.
The film melts at a specific temperature, flows between the surfaces to be bonded, and solidifies upon cooling to form a strong adhesive layer, ensuring a secure bond between heating elements and materials like leather or foam.
From 0.03mm to 0.15mm.
