Chemicals & Petrochemicals

Aniline is primarily used in MDI foams for the automotive and construction industries. Many chemicals can be made from Aniline, including:

• Isocyanaates for the urethane industry
• Antioxidants, activators, accelerators, and other chemicals for the rubber industry
• Indigo, acetoacetanilide, and other dyes and pigments for a variety of applications
• Diphenylamine for the rubber, petroleum, plastics, agricultural, explosives, and chemical industries
• Various fungacides and herbicides for the agricultural industry
• Pharmaceutical, organic chemical, and other products

Persons considering the use of Aniline should be aware of its hazards and take necessary steps to ensure safe handling.

2,4-Toluene diisocyanate is primarily used as a chemical intermediate in the production of polyurenthane products. 2,4-Toluene diisocyanate is extremely toxic from acute (short-term) and chronic (long-term) exposures.

Acute exposure to high levels of 2,4-toluene diisocyanate in humans, via inhalation, results in severe irritation of the skin and eyes and affects the respiratory, gastrointestinal, and central nervous systems (CNS). Chronic inhalation exposure to 2,4-toluene diisocyanate in humans has resulted in significant decreases in lung function in workers, an asthma-like reaction characterized by wheezing, dyspnea, and bronchial constriction.

Animal studies have reported significantly increased incidences of tumors of the pancreas, liver, and mammary glands from exposure to 2,4-toluene diisocyanate via gavage (experimentally placing the chemical in the stomach).

The International Agency for Research on Cancer (IARC) has classified 2,4-toluene diisocyanate as a Group 2B, possible human carcinogen.

Methylene diphenyl diisocyanate, most often abbreviated as MDI, is an aromatic diisocyanate. Three isomers are common, varying by the positions of the isocyanate groups around the rings: 2,2′-MDI, 2,4′-MDI, and 4,4′-MDI.

The 4,4′ isomer is most widely used, and is also known as 4,4′-diphenylmethane diisocyanate. This isomer is also known as Pure MDI. MDI reacts with polyols in the manufacture of polyurethane.

It is the most produced diisocyanate, accounting for 61.3% of the global market in the year 2000.

Polyethylene foam is a strong and resilient closed-cell foam. It is used as the material or component material in shock absorbing products. This closed-cell foam is also implemented to reduce the effects of vibration.

It also is widely used in high resiliency flexible foam seating, rigid foam insulation panels, microcellular foam seals and gaskets, durable elastomeric wheels and tires, automotive suspension bushings, electrical potting compounds, seals, gaskets, carpet underlay, and hard plastic parts (such as for electronic instruments).

Catalyst, in chemistry, any substance that increases the rate of a reaction without itself being consumed. Enzymes are naturally occurring catalysts responsible for many essential biochemical reactions.Most solid catalysts are metals or the oxides, sulfides, and halides of metallic elements and of the semimetallic elements boron, aluminum, and silicon.

Gaseous and liquid catalysts are commonly used in their pure form or in combination with suitable carriers or solvents; solid catalysts are commonly dispersed in other substances known as catalyst supports.

A polyol is an organic compound containing multiple hydroxyl groups. The term “polyol” can have a slightly different meaning in food science and polymer chemistry.

A molecule with more than two hydroxyl groups is a polyol, with three – a triol, and with four – a tetrol. By convention, polyols do not refer to compounds that contain other functional groups.

Cellulose is a polymer with many alcohol groups, but it is not usually discussed as a polyol.
