High-Temperature Resistant Reflectors for Automotive Lighting

Our high-temperature resistant reflectors are engineered for demanding automotive lighting applications where thermal stability is critical. These reflectors utilize specially formulated thermoplastics (PPS, PEEK) that maintain dimensional stability at continuous operating temperatures up to 180°C. The designs incorporate thermal expansion compensation features that prevent distortion during temperature cycling. We apply advanced metallization processes creating aluminum or silver reflective coatings with exceptional adhesion even under thermal stress. The reflectors feature multi-layer protective coatings that prevent oxidation and maintain reflectivity (>90%) in high-heat environments. Our manufacturing process includes rigorous thermal cycling tests (-40°C to 150°C) to validate long-term performance. The reflectors demonstrate excellent resistance to thermal shock, withstanding rapid temperature changes without cracking or delamination. We offer custom solutions for applications near engines or exhaust systems where ambient temperatures are extreme. The products undergo photometric testing before and after thermal aging to ensure consistent light output. Our technical team can develop reflector designs with integrated heat dissipation features for particularly challenging thermal environments.
