Automotive Interior Component Wrapping PUR Adhesive

Automotive Interior Component Wrapping Solutions

Automotive interior components often feature complex contours, narrow edges, corners and irregular shapes. Adhesives used in these applications require strong initial tack, good heat resistance, anti-rebound performance and broad substrate compatibility. Inadequate bonding may cause leather or fabric rebound, edge lifting, blistering and long-term delamination.

SINOHESIVE® PUR hot melt adhesives are developed for wrapping automotive interior components. The system combines rapid hot-melt initial bonding with moisture-curing crosslinking, helping manufacturers achieve stable wrapping performance, smooth surface appearance and durable long-term bonding.

Materials

Rigid Interior Substrates

PP ｜ ABS ｜ Plastic Brackets ｜ Metal Parts

Surface Wrapping Materials

PVC ｜ TPO ｜ PU Leather ｜ Microfiber Leather ｜ Textile Fabrics ｜ PU Foam ｜ Nonwoven Fabric

Compatible with Multi-Layer Structures

The adhesive system supports bonding between common automotive headliner materials, including fiberglass boards, PP/ABS substrates, fabrics, foam, leather and metal components. It is suitable for lightweight multi-layer interior structures.

Heat, Cold and Aging Resistance

After moisture curing, the PUR adhesive forms a durable crosslinked bond layer with good heat stability and flexibility. It helps headliner and sunshade assemblies withstand temperature cycling, summer heat exposure and long-term vehicle use.

Low-Odor, Solvent-Free Technology

SINOHESIVE® PUR hot melt adhesives are 100% solids and solvent-free. They are suitable for automotive interior applications that require lower odor, cleaner processing and controlled VOC performance.
