Bayfol® opens up new worlds of possibility
Bayfol® films particular strength include high chemical resistance, scratch resistance and good forming properties. The engineering thermoplastic films offering customized solutions with distinct functions. Bayfol® HX special films contain photopolymers for use in the industrial holography.
Bayfol® engineering thermoplastic films offer a complementary portfolio of properties to existing polycarbonate films. Customized features providing the perfect performance and functionality for specific applications.
Our Bayfol® HX films are based on RGB light-sensitive photopolymers for the recording of volume holographic optical elements (vHOE). Potential applications of vHOE range from head-mounted displays, 3D glasses for entertainment, automotive head-up displays and lighting, laser strike protection to counterfeit resistant holograms for product protection and labeling of high-value consumer goods.
Bayfol® HX comprises a transparent substrate film, a photoreactive layer with adjustable properties and a protective cover film.
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® HX200 is a light-sensitive, self-developing photopolymer film which can be used to produce phase holograms in the form of volume reflection and volume transmission holograms. Bayfol® HX200 can be recorded with appropriate laser light within the visible spectral wavelength range from 440 nm to 680 nm. For hologram formation no further post-treatment is necessary, e.g. neither wet nor thermal treatment. Bayfol® HX200 consists of a three layer stack of a substrate, a light-sensitive photopolymer and a protective cover film. The substrate is a cellulose triacetate film (TAC), and the protective cover is a polyethylene film (PE). The protective cover film can be removed from the photopolymer.The product is capable of being used for a variety of types of volume holograms. Layer Stack, Schematic
