ChaoYu Series: Non-Erosive Coating for Extreme High-Temperature Resistance
Product Overview
Ultra-high-temperature non-ablative/micro-ablative coatings based on high-entropy ceramic (PHEC) technology, designed for 2200°C thermal shock environments. Includes three grades: HfZrSi-PHEC-PNC, HfZrSi-PHEC-YK, and G20.
Details & Technical Specifications
Series Positioning
The Super Feather series is an ultra-high-temperature non-ablative/micro-ablative coating platform based on the high-entropy precursor ceramic (PHEC) technology. It withstands thermal shocks up to 2200°C, delivering micro/zero-ablation thermal insulation and protection. Designed for CMC ceramic matrix composites surfaces and engine throat liners, it provides a reusable rocket thermal protection solution capable of enduring temperatures up to 2200°C.
