Cylux™

Cylux is a Westlake family of cyclic olefinic materials which have glass-like transparency with excellent electrical properties, good resistance to polar solvents, low moisture absorption and low water vapor permeability. Cylux offers a better balance of optical and mechanical properties versus other transparent plastics and is an excellent substitute for glass in optical parts where shatter resistance and dimensional stability are critical, such as lenses.

The resins used to make Cylux products meet numerous regulatory standards making them suitable for laboratory, diagnostic, medical device and food processing applications. They are both excellent choices for use in healthcare, packaging, and electronics applications. From insulin delivery, to food packaging films, to mobile device components, they are the high-performance material of choice.

Cylux is sterilizable by most standard methods including EtO, gamma, and hydrogen peroxide. It has the best UV transmission of any polymer, which is key for many diagnostic analyses devices. Another advantage of Cylux is its resistance to aggressive polar chemicals. Cylux is highly tolerant of acids, bases, and alcohols, and has some of the lowest water vapor transmission rated (WVTR) of any plastic.

Arguably the leading benefit of Cylux is its extremely high purity and inertness. Its low leachables and extractables make it ideal for direct drug contact.

Cylux is made from resin that is suitable for use in certain food contact applications, contact your local Westlake Plastics representative for specific regulatory declarations.
