In the foam field, most of them are mainly traditional TDI foam, and the shortcomings of this type of raw material foam are less friendly to the manufacturing environment and people, and are also highly regulated chemical raw materials and manufacturing industries.
European countries have begun to replace the old TDI foam manufacturing process with the MDI process foam. Although the cost is slightly higher, MDI is a better alternative and option for the people and the environment to be extended to the user.
AirCloud™ technology foam combines the characteristics of MDI. In addition to the advantages of traditional TDI in the manufacturing environment and human harm, it also provides support and comfort and durability, and can provide meticulous soft and hard according to demand. And the characteristics of quick rebound, slow rebound, and hydrophilicity are more suitable for Taiwan’s climate and usage habits!
HOUSTON (ICIS)–Covestro has declared a force majeure on methylene diphenyl diisocyanate (MDI) and MDI-related products in the US effective as of 13 October, according to a company spokesperson.
The spokesperson attributed the force majeure declaration to an unforeseen shortage of raw materials used in the production of MDI.
According to the ICIS Supply and Demand Database, Covestro can produce 320,000 tonnes/year of MDI from its site in Baytown, Texas.
MDI is consumed mainly in polyurethane foams, which account for about 80% of global consumption. Rigid foams, the largest outlet for MDI, are used mostly in construction, refrigeration, packaging and insulation. MDI is also used to make binders, elastomers, adhesives, sealants, coatings and fibres.
Major US MDI producers include BASF, Covestro, Dow and Huntsman.

There is a technology, very special – in the field of basic chemicals, if your daily life leaves it, the quality of life will be greatly reduced.
This field, called polyurethane, and this technology, is the phosgene chemical technology for the production of polyurethane key material MDI. Countless downstream consumer industries are inseparable from it. For example: your home’s ceilings, walls, refrigerators, sofas, mattresses, as well as the sneakers, shoes we wear, the cotton pads for girls, bags, and even Bra… The main product is MDI, the chemical name is ” Diphenylmethane diisocyanate”.
