HTLT™ is an ultra-high temperature, optical grade thermoplastic that is characterized by a high index of refraction, excellent transmission, and a sustained operating temperature up to 150° C. It is a tough, impact resistant thermoplastic that can be injection molded with precision detail at high production rates for the photonics industry, including primary and secondary LED applications. Given its high glass transition temperature and excellent thermal insulation properties, HTLT™ is suitable for use in solder reflow processes including lead-free solder reflow applications. HTLT™ Thermoplastics are available in several grades and are recommended for use photonics applications including general illumination, automotive lighting, backlighting for mobile appliances and computers, display lighting for signage and advertising, light pipes and reflectors, infrared electronic switching devices, lasers, infrared fiber optic cable, digital cameras, and solvent cast films. Product sheets are listed below. |
