WebDec 10, 2024 · Placcel®CD205Pl, CD220Pl and 220EC are liquid-type, co-polycarbonate diols that produce polyurethanes with low crystallization tendencies, but also lower modulus values. They are hexanediol-polycarbonate diols with a second diol comonomer, or in the case of 220 ED, caprolactone as the third monomer. These polycarbonate-urethanes … Web欢迎您访问武汉艾美捷科技有限公司官方网站!
