We are the first to produce MR-Thermal by EHV polymer condensation polymerization process. As new generation of environment friendly insulation material, MR-Thermal enjoys many advantages, such as no smoke and no poison, fireproof and thermal insulation, waterproof and moisture-resistant, anti aging and anti corrosion, sound proof, energy saving, heat resistance, and less shrinkage and brittle under low temperature, so its derivative products have been successful used in NASA and war industry. Meirun has successfully introduced it as the perseveration cavity of flat plat solar energy products.
