Isocyanates are compounds containing the isocyanate group (-NCO). They react with compounds containing alcohol (hydroxyl) groups to produce polyurethane polymers, which are components of polyurethane foams, thermoplastic elastomers, spandex fibers, and polyurethane paints.

Isocyanates are a family of highly reactive, low molecular weight chemicals. They are widely used in the manufacture of flexible and rigid foams, fibers, coatings such as paints and varnishes, and elastomers, and are increasingly used in the automobile industry, autobody repair, and building insulation materials.

2019年6月18日 · Isocyanates are a class of highly reactive, powerful compounds that react with alcohol-based compounds to produce polyurethane polymers and certain solvent-based paints.

Many workers are unaware of the potential hazards that chemicals present in their work environment, which makes them more vulnerable to injury. The following references aid in recognizing and evaluating hazards associated with isocyanates in the workplace. OSHA Technical Manual (OTM). OSHA Directive TED 01-00-015 [TED 1-0.15A], (January 20, 1999).

An isocyanate is a compound containing the isocyanate functional group –N=C=O, which is highly susceptible to reaction with the hydroxyl groups of cellulose and lignin in fibers. From: Tribology of Natural Fiber Polymer Composites , 2008

2013年11月25日 · The health effects of isocyanate exposure include occupational asthma; skin irritation (dermatitis); irritation to the mucous membranes, eyes, nose and throat; gastrointestinal irritation; chemical bronchitis; and pneumonitis.

Isocyanates in the workplace can present significant risks to workers. Workers exposed to isocyanates can develop a range of short and long-term health problems. What are isocyanates? Isocyanates are hazardous chemicals.

Isocyanates are a family of organic chemicals which have one or more N=C=O functional groups bonded to the molecule[1]. The most common isocyanates found in industrial settings are based on molecules with 2 such functional groups, and are generally referred to as diisocyanates, these include: TDI, MDI and IPDI exist as a mix of isomers.

Isocyanates result from chemical reactions in plastics and polyurethanes. Workers who manufacture plastics or apply polyurethane coatings may be at risk of exposure. Inhalation is the most common form of exposure for workers. Isocyanates can also enter a worker's body through unprotected skin.

Isocyanates are a group of highly reactive organic compounds that can easily become volatile and enter the atmosphere as a vapour. They are common components in the production of polyurethane foams and 2-pack spray coatings used to provide a protective coating over a range of materials including cement, wood, fiberglass, steel and aluminium.
