Automotive and EV electronics operate under continuous heat, vibration and thermal cycling. OEMs and Tier-1 suppliers require:
HN-8830A/B combines high heat transfer with rubber elasticity across a broad temperature range, resisting thermal cycling without cracking. Its 1:1 ratio and 30-minute 80°C cure suit automated automotive lines, while UL94 V-0 and ≥1.0*1014 Ω·cm insulation support safety and reliability goals.
This addition-cure silicone may fail to cure in contact with organotin/tin-containing silicones; sulphur, polysulphides or sulphur-containing articles; amines, polyurethane rubber or ammonia-containing items; phosphorus compounds; organic acids; and solder-flux residues. Substrates and tools must be clean and free of these contaminants. Do not use in contact with condensation-cure (acetoxy) silicone, epoxy resin or polyurethane.
What thermal conductivity does HN-8830A/B provide? 3.0 ± 0.1 W/m·K.
Is it suitable for EV DC-DC converters? Yes — it is designed for EV DC-DC converters and automotive power modules.
What is the operating temperature range? −40°C to 200°C.
How long does it take to cure? 4–8 h at room temperature, or 30 min at 80°C.
For automotive and EV electronics manufacturers, HN-8830A/B delivers high thermal conductivity (3.0 W/m·K), UL94 V-0 flame retardancy and reliable −40°C to 200°C performance with convenient 1:1 processing.
