However, it comes with clear limitations. It brings difficulties in processing and operation. Meanwhile, MDI is demanding in storage. It reacts easily with moisture in the air, which leads to material degradation. Strict temperature and moisture isolation measures are mandatory throughout storage, adding extra complexity to the whole production chain.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p

custom polyurethane manufacturer, the first questions are usually not about appearance or price. They need clear answers: MDI is widely adopted as raw material for FDA-qualified polyurethane. However, it comes with clear limitations. It brings difficulties in processing and operation. Meanwhile, MDI is demanding in storage. It reacts easily with moisture in the air, which leads to material degradation. Strict temperature and moisture isolation measures are mandatory throughout storage, adding extra complexity to the whole production chain.
