toluene diisocyanate uses

sector has weathered the economic storm better than the aliphatic diisocyanates. These formulants meet defined criteria for carcinogenicity, neurotoxicity, chronic effects, adverse reproductive effects and ecological effects as well as Track 1 substance criteria as defined under the Toxic Substances Management Policy (TSMP) or are substances designated under the Montreal Protocol. lower-budget items such as furniture and bedding. high performance anti-corrosion coatings. where the foam takes on the required shape without a great characteristics. Did you know that every day you use many products made better with diisocyanates? This is achieved by the reaction of TDI Total of all isomers, including, but not limited to, isomers with CAS RN 354-12-1, 354-15-4 and 354-21-2. Most Canadian releases of TDI to the environment occur in Ontario. The toluene removal efficiency was 70 per cent in Tween 81. Repeated or prolonged contact with the liquid may cause removal of natural lipids from the skin resulting in dry, fissured dermatitis. Aliphatic diisocyanates — used since the late 1940s — have been extensively studied. It is also used as cement for fine polystyrene kits as. manufactured from flexible PU foams. [3] There are numerous other synonyms and product names; see the Hazardous Substances Data Bank (HSDB) for more information. However, SRI expects demand for flexible foams will return to TCC’s TDI 80-20 is a mixture blend of 80% 2,4-toluene diisocyanate and 20% 2,6-toluene diisocyanate. [1] They are highly reactive compounds widely used to manufacture polyurethane foams and coatings. 1986/164, Guidelines for Canadian Drinking Water Quality, Exposure Guidelines for Residential Indoor Air Quality, Contaminated Sites Regulation B.C. where it gradually expands into a large bun of foam. and chemical resistance. [1] Epidemiological studies looking specifically at TDI exposure and human cancer are limited; other studies that included TDI as an exposure did not identify strong and consistent associations between TDI exposure and cancer in humans. Toluene diisocyanate–based rigid polyurethane foam is used in household refrigerators and for residential sheathing or com-mercial roofing in board or laminate form (IARC 1986). Remember Me TCC’s Toluene Diisocyanate TDI 80-20 is a toxic and highly reactive organic compound. Toluene Diisocyanate Blogs, Comments and Archive News on Toluene diisocyanate (unspecified isomer) 26471-62-5: 100 pounds: X: U223: 10000 pounds: Toluenediisocyanate (mixed isomers) 26471-62-5: 100 pounds: 313: U223: 10000 pounds "X" indicates that this is a second name for an EPCRA section 313 chemical already included on this consolidated list. Aliphatic DII are straight-chain compounds while Aromatic DII is cyclic. Speak to ICIS, Sign up for our ICIS newsletters to receive the latest market developments, headline news and insights into Chemical price changes and the impact on markets. Polyurethane coatings are one of the fastest growing sectors driven by improving living standards. 375/96, Ontario Drinking Water Quality Standards, O Reg 169/03, Regulation respecting the quality of drinking water, CQLR c Q-2, r 40, List of all Challenge Substances – Chemicals Management Plan, National Pollutant Release Inventory: Substance list, Pest Management Regulatory Agency (PMRA) List of Formulants, National Classification System for Contaminated Sites (2008), Revised Great Lakes Water Quality Agreement of 1978, Air Standards for Toluene Diisocyanate (TDI), Pollution Prevention Planning Notice for the Polyurethane and Other Foam Sector (except Polystyrene) in Respect of Toluene Diisocyanates (TDIs) (2015), National Pollutant Release Inventory (NPRI) Facility Search, Environmental Health Criteria 75, Toluene Diisocyanates, DSL – high priority substance with greatest potential for exposure (for mixed isomers) and intermediate potential for exposure (for 2,4-TDI and 2,6-TDI individually), Recommended to be added to the toxic substances list, Environment Canada’s National Pollutant Release Inventory, NPRI Part (Threshold Category): 1B, Reportable to NPRI if manufactured, processed, or otherwise used at quantities greater than: 100 kg. corrosion and abrasion, and flexibility. I agree to the With the economic downturn, flexible PU foams demand has PMDI is a highly versatile product used to produce a wide variety of rigid, flexible, semi-rigid and polyisocyanurate and thermoset … All these biological treatment methods can convert toluene into. [1,4], The toxicity of TDI has been recognized for many years. The largest industrial groups exposed are plastic product manufacturing, automotive repair and maintenance, motor vehicle parts manufacturing, and furniture and cabinet making. grow at 2-4%/year up to 2013. The most common form of TDI offered commercially is an 80/20 mixture of the 2,4- and 2,6-isomers but is also available as a 65/35 mixture as well as a pure 2,4-isomer. Toluene may have local as well as systemic harmful effects. [2], In Canada, a potential source of TDI exposure to the general population is industrial releases during urethane foam manufacture and processing. Dispose of toluene-soaked materials into approved waste cans with a self-closing lid. Make fast and confident decisions and gauge the best time to buy or sell. Applications of Toluene Toluene has numerous commercial and industrial applications and is a solvent in paints, lacquers, thinners, glues, correction fluid and nail polish remover, and is used in the printing and leather tanning processes. with a polyol to produce the foam. Automotive sales in China passed the When possible, use methods that release less product into the air (e.g., a paint roller instead of a spray gun). Diisocyanates used in polyurethane production are divided into two types: [4], TDI are also used as a cross-linking agent for nylon-6 and as a hardener in polyurethane adhesives. All facility owners and operators have been compliant with the plan. The section in this information sheet entitled "Preventive actions and reducing risk" communicates updates in risk management activities, namely: You will not receive a reply. Toluene is an aromatic hydrocarbon solvent and natural sources of toluene include crude oil and small quantities it is found in tolu tree.Toluene alternative names include methylbenzene, toluol, anisen, phenyl methane.Toluene is produced during the process of making gasoline and other fuels from crude oil, in making coke from coal, and as a by-product in the manufacture of styrene. binder for wood and to produce mold cores for the foundry industry. It may cause irritation of the eyes, respiratory tract, and skin. The assessment indicated that Canadians may be exposed to TDIs mainly through inhalation during the use of non-foam products available to consumers.
