Storage & Handling
PC is extremely moisture-sensitive. Must use a desiccant dryer. Store sealed. Excessive moisture causes silver streaking and bubbles in molded parts.

Product Overview
Infrared PC (grade PC 9227H) is an IR-transmissive polycarbonate: 92% IR transmittance at 850 / 940 / 1400 nm (ISO 13468, 2 mm), with a dark visible-light appearance that still passes infrared. Tensile strength 62 MPa, notched Charpy 60 kJ/m² (ISO 179, 23°C), MFR 20 g/10min, easy release, UL94 V-2 at 1.6 / 2.0 / 3.2 mm. It suits remote-control IR windows, IR sensor covers and receiver housings that must hide internals while passing the IR signal.
Transmittance is measured on 2 mm specimens; real-part wall thickness, colour and surface finish affect signal passage, so validate on the finished part. Send grade, colour, wall thickness, monthly volume and destination for a quote; samples are available for mould trials.
Applications in Detail
Remote-control IR windows
92% transmittance at 850 / 940 nm (2 mm) covers common remote and IR-receiver wavelengths; the dark appearance hides internal circuitry for a cleaner product look. Keep window walls uniform and avoid weld lines across the optical path to stabilise the signal.
IR sensor covers
For outer covers of IR proximity, ranging and sensing devices, the dark finish blends into the device panel. 60 kJ/m² notched impact and easy release help thin-wall covers mould well; validate the signal at the sensor's actual wavelength and cover curvature.
Electronics & meter windows
Suits device windows needing IR communication or indicators, such as smart meters and appliance panels. UL94 V-2 at 1.6 mm meets general enclosure needs; if the product requires V-0, choose the flame-retardant PC or a custom grade.
Frequently Asked Questions
Under what conditions is the 92% IR transmittance measured?
Per ISO 13468 on 2 mm specimens, 92% at each of 850 / 940 / 1400 nm (see the TDS on this page). Different wall thickness, texture or coatings change transmittance — measure the signal on the finished part.
Is it clear or black?
It has a dark, visible-light-blocking appearance that hides internals while passing infrared — exactly the purpose of an IR-window resin. Exact colour and darkness can be customised; confirm against a sample plaque.
How should processing and drying be set?
Dry at 110–120°C for 4–5 h, melt 280–320°C, mould 70–110°C, upper limit 290°C, medium back pressure and moderate injection speed. Easy release helps thin-wall window parts; adjust to machine and mould.
