White Non Woven EVA Web Hot Melt Adhesive For Automotive Sun Visor Bonding

A non-woven, mesh-like sheet of thermoplastic adhesive made from ethylene-vinyl acetate (EVA) or other polyolefin systems (e.g., PE, PP, metallocene-modified PO). The web structure provides low add-on weight, breathability, and easy handling compared with films or liquid glues.

EVA/PO hot-melt webs are a cost-effective, fast, and soft-hand solution for sun visor laminations, ideal for fabric↔foam and foam↔core bonds. Choose lower-softening EVA for textile comfort layers and higher-softening PO/EVA for PP core bonding and hotter climates.

Equipment: flatbed press, belt/continuous roller laminator, heated platen, or calendar line.

Typical processing parameters (tune per grade & stack):

• Bondline temp: EVA 120-150 °C; PO 130-170 °C at the interface
• Dwell time: 5-20 s in press (continuous lines: equivalent thermal exposure)
• Pressure: 0.2-0.6 MPa (enough to wet foam/fabric without crushing)
• Cooling: Under light pressure to lock the bond and avoid spring-back

Tips: pre-dry hygroscopic fabrics; avoid overheating foams; use release paper or PTFE belt to prevent sticking; keep web centered to avoid squeeze-out lines.

• Solvent-free, low VOC, clean processing
• Fast, reworkable thermoplastic bonds
• Soft hand, drape, and conformability (ideal for foam and textile laminations)
• Broad compatibility with foams, fabrics, and many plastics used in interiors
