Technical application solution: self-adhesive heat shields
Application overview
In the automotive industry, heat shields are essential for protecting components from high temperatures. More and more, self-adhesive heat shields, laminated with pressure-sensitive adhesives (PSAs), are being chosen over mechanically fastened options. This change helps accommodate slimmer designs, reduce vibration noise, and eliminate the need for extra tooling. These self-adhesive solutions need to stick to tough surfaces and hold up in harsh environments. They’re commonly used in areas like gas tanks, cabin exteriors, and wheel wells.
Materials and bonding requirements
Material laminated to: Non-woven polyester and glass fiber composite with a foil facing.
Material bonded to: Substrates like polycarbonate, ABS, paint/powder-coated metal, PP, and PE.
Technical challenges
PSAs in these applications need to meet a few key performance standards: Adhesion: They must have enough adhesive mass to bond well to irregular or rough surfaces.
Resistance: They need to stand up to heat, abrasion, and chemicals, ensuring durability in tough conditions.
Convertibility: The adhesive should be easy to convert, with excellent die-cutting properties and a tear-resistant PP liner option. Substrate compatibility: They must bond effectively to low surface energy substrates, which are common in automotive parts.
Compliance: The adhesive must meet strict Automotive OEM specifications.
Product offerings
We offer a range of PSA products designed to meet these needs, including:
- FT 3014
- FT 3043
- FT 1914 PP
- FT 1943 PP
- FT 1149X
- FT 1124 12 Pt. Bd.
These products are available as transfer tapes with both single- and double-liner options and are ready for use in automotive manufacturing.
