What is the waterproof and moisture-proof performance of SEPS graphite floor heating module in COSMO, Cosman?

SEPS graphite floor heating mold in COSMO, Cosman, has a closed closed-cell structure, and the molecular structure of polystyrene itself is non-absorbent; After adding graphite particles, the foamed particles are more dense, and there is no gap between the front and back of the board, so the water absorption is extremely low and the moisture-proof and seepage-proof performance is excellent. General rigid foam thermal insulation materials will age after several years of use, leading to water absorption and performance degradation. SEPS graphite floor heating die has excellent corrosion resistance, aging resistance and heat preservation, and can still maintain its excellent water absorption resistance under high steam pressure ∞ and its service life can reach 30-40 years.
