The information contained in this chemical compatibility guide is believed to be reliable but has been compiled from numerous industry sources and should be used as a general reference guide only. The major products include MDI (diphenylmethane diisocyanate), TDI (toluene diisocyanate), caprolactam, adipic acid, polyamide 6 and 6. The 4,4' isomer is most widely used, and is also known as 4,4'-diphenylmethane diisocyanate. The spontaneous chemical reaction of the various kinds of MDI with primary or secondary amines or substances with ‐COOH, ‐OH or ‐SH groups is exothermic and complete within seconds or minutes. Low density MDI based systems could provide significant benefits over a TDI based system in manufacture of tall (> 2 meters tall) cylindrical foams for laminated foam applications. Application Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. The major focus of disease prevention efforts to date has been respiratory tract exposure; however, skin exposure may also be an important route for inducing immune sensitization, which may promote subsequent airway inflammatory responses. In these types of air quality issues, values such as the National Ambient Air Quality Standards (NAAQS) should be used rather than emergency response guidelines. temperature reaches the boiling point of water, and the reaction forming carbon dioxide will accelerate. In pharmaceutical preparations it is primarily used as a diluent (10–90% w/w) in tablet formulations, where it is of particular value since it is not hygroscopic and may thus be used with moisture-sensitive active ingredients. The workplace: storage and use of MDI and TDI 86 Designing the systems and minimizing the risks 87 Physical and chemical properties relating to storage and processing 93 Storage of MDI and TDI 95 Safety issues in workplaces using MDI and TDI 106 Safety issues in some important polyurethane processes 117 Use of MDI and TDI in laboratories 122. "X" indicates that this is a second name for an EPCRA section 313 chemical already included on this consolidated list. recommended that chemical goggles be worn) and protective clothing impervious to MDI whenever MDI is used. A provider of chemical injections systems, Drover Energy approached MDi for a customized LevelCon solution for monitoring fluid levels and controlling injection rates. 5% pure alumina for excellent wear and trouble-free service. Officials behind a $1. We’re expanding the scope of our TDI business and aggressively developing specialty products. mdi We are now supplying chemical materials satisfying customer's needs! Characteristics of Product COSMONATE M-200 is polymeric MDI, generally used in manufacturing hard and semi-hard polyurethane foam. Using Your Metered Dose Inhaler (MDI) Canister Boot Dosing Chamber Mouthpiece A metered dose inhaler (MDI) is a small device that delivers a measured amount of medication to your lungs. While working with material safety data sheets (MSDS), I found that manufacturers sometimes used obscure names for constituent chemicals and I didn't always have. I was a little nervous and a little tense. WANNATE® MDI-50s by Wanhua Chemical is a mixture of 2,4’- and 4,4’-diphenylmethane diisocyanate. The second edition of the “Emergency Response Manual for Transport of TDI and MDI”, dated October 2003, has been thoroughly reviewed. 1 billion MDI plant in Louisiana, US. TDI is used in the production of thousands of products around your home. Ceramic shaft and thrust washers are 99. Another area of MDI preference is to produce low density HR foam using auxiliary blowing agents. Albuterol sulfate is a salt mixture containing the chemical compound albuterol. This structure is a strong chromophore resulting in the yellowing of urethanes. It is solvent-free form with 2. F012 Quenching wastewater treatment sludges from metal heat treating operations in which cyanides are used in the process. The vapor pressure of MDI is low at room temperature (<1 X 10-5 mm Hg). The two commercial isomers of TDI are shown in Figure 4. Blank about Senior Healthcare. The metered dose inhaler has a propellant in which the ingredients are suspended. Occupational Hygiene Air Monitoring for MDI and TDI Guidance Subject: This guidance document describes workplace air monitoring methods for MDI and TDI, and provides information on personal and area sample collection.
