Key properties:
• High resistance to chemicals
• Excellent for cold forming between 23 and 100 °C,
• Good ink adhesion e.g. for screen printing
• Good punching characteristic
• Long term temperature stability up to 100 °C
• Thickness range: 125 to 500 microns
• Surface quality: gloss/gloss or gloss/fine matte
Typical Applications:
• Automotive interior panels, control surfaces,
• Electronics housings, switches and membrane keypads
• Industrial nameplates and graphic overlays
• Consumer goods and decorative components
Bayfol® LR 5902 is dry, i.e. non-tacky at room temperature, solvent-free, and forms irreversible cross-linked bonds after heat-activation.
The resulting chemical bonding is permanent and irreversible, creating an extremely durable connection that not only withstands low and high temperatures and aggressive chemicals, but is also resistant to decomposition and hydrolysis.
Key properties:
• Excellent adhesion strength across a variety of board materials
• Fast curing with long-lasting durability
• Excellent resistance to chemicals, aging, and hydrolysis
• Low processing temperature and short processing time
• Ability to bond complex designs (curved/irregular shapes)
• Minimal glue overflow and small thickness deviation
• Solvent-free processed on releaser liner (standard: silicon paper)
• Variety of standard weight per unit area
These properties make it specifically suitable for sensitive materials such as glass, fabrics, synthetic leather, and magnetic surfaces.
Potential applications:
• Back cover bonding
• Watch glass bonding
• Fabric/leather material and accessory bonding
• Electronic component bonding
• Flexible printed circuit (FPC) bonding
Excellent inter-layer bonding prevents delamination over the packaging's lifetime, and the film remains easy to thermoform.
Key Properties:
• Multi-layer film with one soft, one hard side
• Outstanding resistance to cracks, puncture and abrasion
• ISO 10993-5 and USP Class VI compliant
• Excellent processibility (thermoforming)
• Sterilizable (by EtO, Gamma)
• Available as blue tinted version
Key Properties:
• Full RGB recording range (440–850 nm)
• Self-developing — no wet or thermal post-treatment required
• Tunable angular and spectral selectivity
• Superior optical clarity and invisible "off-Bragg" transparency
• Roll-to-roll (R2R) manufacturing compatible
• Three-layer architecture: substrate film / photopolymer layer / protective cover film
Available in a range of surface finishes, thicknesses and grades, Bayfol® films can be fully customized to meet your specific functional and aesthetic requirements.
Featured Products
Bayfol® HX120 is a light-sensitive, self-processing photopolymer film which can be used to manufacture reflection and transmission volume-phase holograms. Bayfol® HX120 film can be recorded with appropriate laser light within the spectral range of 440 nm to 680 nm and is optimized for the spectral range of 500 nm to 680 nm.Bayfol® HX120 film consists of a three layer stack of a substrate, the light-sensitive photopolymer and a protective cover film. A triacetate (TAC) substrate and a polyethylene terphthalate (PET) protective cover film are used.
Bayfol® LR 5902 is a latent reactive adhesive film, a so-called thermoset adhesive of a polyurethane (PU) polymer.
The film is designed for low temperature activation bonding on wide range of substrates, supplied on a silicone paper as release liner.
Color: natural, black / other colors on request.
