Advantages compared to other insulation materials

Comparison Items	Phenolic Cotton Cloth Board	Shortcomings of Competitors
Comprehensive Cost	￥200 - 400/㎡ (Epoxy board costs over ￥600/㎡)	The processing loss rate of mica board is as high as 15%.
Processing Convenience	Can be directly stamped and formed (no special cutting tools required)	Fiberglass board requires dedicated CNC equipment.
Environmental Performance	Biodegradable (cotton cloth substrate)	Epoxy laminates have high disposal costs for waste.
