Tolune diisocyanate (TDI) is an isocyanate used in the production of polyurethanes for flexible foam applications, ranging from furniture, bedding, and carpet underlay to transportation and packaging. TDI is also used in the manufacture of coatings, sealants, adhesives and elastomers.
Nylon is a generic designation for a family of synthetic polymers known generically as aliphatic polyamides derived from benzene, first produced in 1935 by DuPont. Nylon can be used to form fibers, filaments, bristles, or sheets to be manufactured into yarn, fabric, and cordage; and it can be formed into molded products. Nylon is tough, elastic and strong, and it has high resistance to wear, heat, and chemicals. It is generally used in the form of fine filaments in such articles as hosiery and sports equipment, e.g., parachutes; but its applications also include engineering plastics for cars, toys, healthcare products, carpets, roller-blade wheels and ship sails.
There are many varieties of nylon that have their own characteristic properties. Nylon plastics are used for making such products as combs, brushes and gears. Nylon yarns, on the other hand, are used for making nylon fabrics. When talking about nylon textile, there are two types that are mostly prevalent in the market: nylon 6-6 (also written as nylon 6,6) and nylon 6.
Phenol is an aromatic alcohol, mainly used as an intermediate in organic synthesis. Essentially, it serves as a raw material for the production of bisphenol A, phenolic resins, alkylphenols and caprolactam. It is a poisonous, acidic compound obtained from coal tar or benzene and used mainly as a disinfectant or antiseptic, carbolic acid; any hydroxyl derivative of benzene. Phenolic resins are manufactured from phenol. They are used in wood products and molding powders applications, and also have a wide range of applications on the electrical, mechanical and decorative markets, in the automotive industry, in building and construction, in thermal insulation products and in foundry industry products.
Epoxy resin is a flexible resin made using phenols and used chiefly in coatings, adhesives, electrical laminants and composites for its excellent adhesion, strength and chemical resistance. Polycarbonates are a particular group of thermoplastics. They are easily worked, molded, and thermoformed; as such, these plastics are very widely used in modern manufacturing. Polycarbonate is becoming more common in housewares, as well as laboratories and in industry. It is often used to create protective features, for example, in banks as well as vandal-proof windows and lighting lenses for many buildings.
