Polycarbonate Blend Films and Special Films
Bayfol® CR is the brand name for our blend films made from polycarbonate and other engineering thermoplastics.
The transparent, translucent and opaque blend films have strengths including high heat resistance, impressive stiffness, good electrical insulation properties and excellent printability. Depending on which thermoplastic is blended with the polycarbonate, benefits can include better resistance to chemicals, greater elasticity and enhanced dynamic strength.
Bayfol® CR also processes easily for hot and cold forming. Specific product groups are available for our customers depending on their intended Bayfol® CR application
Bayfol® HX are our special films based on light sensitive photopolymers.
We are developing these unique photopolymers as a technology platform, targeting at tailored film-based solutions for a newly developing world of industrial holography. The target applications are manifold, reaching from holographic light-guiding elements for coming generations of mobile IT displays, head-mounted displays, automotive virtual reality displays or counterfeit resistant holograms for product protection and labeling of high-value consumer goods.
In focused customer development projects we want to help the industry to benefit from these new opportunities in diffractive optics, that everybody was dreaming about for a long time.
Bayfol® CR is a blend film of polycarbonate and polyester. This grade has outstanding cold-forming properties e.g. by high-pressure forming and has become established in the film insert molding (FIM) decoration process. Bayfol® CR has excellent chemical resistance and flexibility. The latter makes Bayfol® CR the optimum grade for producing film keypads and membrane switches.
Bayfol® CREC is an extruded film based on a PC/PBT blend. Like Bayfol® CR, it comprises good forming properties and chemical resistance as well as color stability at elevated temperatures. Bayfol® CREC is perfectly suitable for printing applications. Like Bayfol® CR, Bayfol® CREC is used in particular for membrane switch overlays, nameplates, keypads and control panels.
Bayfol® HX products are available as light-sensitive photopolymer films on optical quality substrates. The films are self-developing under light and do not require costly chemical or thermal treatment during processing. Bayer MaterialScience offers ready-made products but is also capable of customizing the specification to meet customers’ requirements on light sensitivity, spectral properties, support film properties, and more.
