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
High-heat PC (grade PC 9070H) is a heat-resistant transparent polycarbonate: HDT 155°C (ISO 75, 1.82 MPa, unannealed), tensile strength 70 MPa, notched Charpy 55 kJ/m² at 23°C and 38 kJ/m² at -30°C, transparent with UL94 HB. It suits parts near heat sources that also need clarity and impact resistance, such as headlamp internals, connectors and high-temperature meter housings.
HDT is a deflection temperature under test load, not a continuous-use temperature; validate weathering and ageing for long-term outdoor use. Send grade, colour, wall thickness, monthly volume and destination for a quote; samples are available for mould trials.
Applications in Detail
Headlamp components
HDT 155°C and 55 kJ/m² notched impact suit transparent or translucent lamp internals near the light source, such as brackets and bezels. Outer lenses in long-term outdoor use need separate weathering, ageing and hard-coat validation; this grade makes no UV-stability claim.
Electrical connectors
CTI 450 V, glow-wire GWFI 960°C (1.5 mm) and surface resistance 1.00E+16 Ω support insulation needs in hot environments; transparency helps assembly inspection. Validate end-product electrical safety against the target standard.
Outdoor products & hot meter housings
Notched impact stays at 38 kJ/m² at -30°C, resisting brittle failure outdoors in cold; HDT 155°C covers most meter housings near heat sources. Run ageing tests in the target environment for long-term sun/rain exposure, or switch to a UV-stable grade where needed.
Frequently Asked Questions
How does it differ from standard transparent PC?
This grade's HDT is 155°C (1.82 MPa, unannealed), above standard transparent PC, suiting parts near heat sources while keeping clarity and 55 kJ/m² notched impact. HDT is not a continuous-use temperature; validate against the real heat load.
Can it be used for outer headlamp lenses?
It suits lamp internals and structures near heat. Outer lenses in long-term outdoor service need weathering, chemical-cleaner and hard-coat validation; this TDS does not state UV stability, so prefer the UV-stable lighting-grade PC or a custom grade for outer lenses.
What should I watch in processing?
Melt temperature 330–340°C, higher than standard PC; dry at 110–120°C for 4–5 h, mould 90–110°C, upper limit 340°C. Avoid long residence times to prevent degradation and yellowing; adjust to machine and part.
