Specialty additives pigments

The term filler is very broad and encompasses a very wide range of materials. We arbitrarily define in this book as fillers a variety of natural or synthetic solid particulates (inorganic, organic) that may be irregular, acicular, fibrous or flakey and are used in most cases in reasonably large volume loadings in plastics, mostly thermoplastics. Continuous fibers or ribbons are not included. Elastomers are also not included in this definition as well as many specialty additives that are used at low concentrations (e.g. pigments, lubricants, catalysts, etc). 

They may not provide superior hiding or coverage because these properties are not as important for primers as they are for topcoat paints. Primers may also contain specialty pigments and additives to help resist corrosion or prevent stain bleed-through. 

Specialty chemicals are formulations of chemicals containing one or more fine chemicals as active ingredients. They are identified according to performance properties. Customers are trades outside the chemical industry and the public. Specialty chemicals are usually sold under brand names. Suppliers have to provide product information. Subcategories are adhesives, agrochemicals, biocides, catalysts, dyestuffs and pigments, enzymes, electronic chemicals, flavors and fragrances, food and feed additives, pharmaceuticals, and specialty polymers (see Chapter 11).

We estimate that biotechnology will be competing with approximately 30 percent of the total chemical market by 2010 on the basis of lower cost and/or superior product features. Approximately 10 to 20 percent of basic and intermediate chemicals could be affected by production through modern fermentation. Specialties will be replaced by enzymes and natural flavors, pigments and additives. Polymers will face competition from biopolymers that are competitive in price with both polyester and nylon.

Other apphcations that have been developed for PET fibers include the incorporation of fragrances, antibacterial or absorbent additives, and also pigmented fibers for permanent coloration. Here again, the bico technology offers a route to such specialty fibers with lower raw material costs and fewer processing faults.
