Novel hard-block-only polyurethanes are prepared from 1,4-butanediol (BDO) and a pre-polymer synthesized separately from 1,3-bis (4-hydroxybutyl) tetramethyl disiloxane (BHTD) and 4,4'-diphenylmethane diisocyanate (MDI). Three (co)polymers using different proportions of these chain extenders were synthesized using reaction injection moulding, and their

4,4'-Methylenediphenyl diisocyanate (MDI) is the most important of the isocyanates used as intermediates in the chemical industry. Among the main types of damage after exposure to low levels of MDI are lung sensitization and asthma. Albumin adducts of MDI might

Orthopedic plaster casts contain methylene diphenyl diisocyanate (MDI). A few case reports have suggested occupational asthma to MDI in casting work. However, the knowledge of the exposure levels related to the occupational asthma cases is lacking. We report on two

Polymeric methylenediphenyl diisocyanate (MDI) is a high production volume chemical intermediate consisting of monomeric 4,4'-MDI, its 2,2'- and 2,4'-isomers, and higher oligomeric homologues. The toxicity of pMDI has systematically been investigated in previous regulatory and mechanistic studies. One cornerstone of

It is well known that the use of MDI (methylene diphenyldiisocyanate) as an alternative for formaldehyde-based resins is seen as a responsible option to reduce formaldehyde emissions for CWP (Composite Wood Products) in buildings. However, there are concerns raised regarding
