万华化学：公司为全球MDI行业的龙头，国内及亚太地区最大的MDI制造企业，拥有380万吨MDI产 能；公司此前宣布将从12月1日起，上调在东南亚及南亚地区的聚合MDI与纯MDI产品价格，调涨幅度 为200美元/吨。 据生意社12月3日消息，匈牙利宝思德公司宣布1日起对所有MDI产品涨价，涨幅均为300欧元/吨（约 2400人民币）。 消息面上，据慧正资讯，亨斯迈位于荷兰罗曾堡的28万吨/年MDI装置于11月21日前后意外停车检修， 预计停产将持续至少一个月，其另一套16万吨/年装置也同步降至低负荷运行。此外，近期MDI行业进 入密集检修期，在供应收缩预期推动下，国际巨头巴斯夫、万华化学相继提价。 东方证券表示，从下半年的MDI行情来看，纯MDI由于供需更集中于国内，且保质期短难以库存，在下 游氨纶等需求并不旺盛的情况下，价格已经回到去年年末的高点。虽然当下并不是MDI需求的旺季，但 供给端的意外收缩，有望催动MDI价格反弹。而且MDI供给格局与需求情况更好于TDI，不排除本次事 件成为行业中长期拐点的可能。 公司方面，据上市公司互动平台表示， 氯碱化工：公司参股30%上海亨斯迈聚氨酯和15%上海联恒:上海亨斯 ...
