Agrochemicals

This category is for websites representing companies or agents that specialize in the agrochemicals industry, ranging from manufacturers to consultants for farmers.

Please only suggest websites to this category that contain information on products and services directly related, and specializing in agrochemical industry. Please try to select the most specific sub-category or link, following the strategy in Business charter.

Associations

Please submit only sites for associations or other organizations whose scope encompasses the chemical industry as a whole.

Associations where the membership is limited to a specific chemical industry sector (for example, an association of adhesives manufacturers) should be submitted to the appropriate sub-sector category.

Basic Chemicals

This category comprises establishments which are primarily engaged in production of chemicals using basic processes, such as thermal cracking or distillation. Basic chemicals are generally used as raw materials for further chemical intermediates or final chemical products. Also included in this category and its subcategories are support industries such as associations, wholesalers, importers, and media that focus on the basic chemicals sector.

Please submit sites to the most relevant subcategory, defined by the types of chemicals produced. If you have trouble finding the most appropriate category to submit to, you may wish to use ODP''s Curlie function with the chemical name or type as a keyword.

Biochemical

Sites for the industrial sector specializing in chemicals derived from animals and plants.
Biochemicals differ from Organic Chemicals in that they were discovered from their synthesis within living cells, but many can now be produced synthetically from simple chemicals.

Please submit sites to the sub-category or linked category according to the primary product on the site, eg. Biopolymers/Proteins.
If the primary products are manufactured by chemical synthesis, consider submitting to the Organic category instead. More complex organic compounds may be considered for sub-categories of Science/Chemistry/Organic/Products_and_Services instead. If the scope of products covers more than one sub-topic, then please submit to either Manufacturing or Wholesale_and_Distribution as appropriate.

Catalysts and Adsorbents

Manufacturers and suppliers of catalysts and adsorbent materials. Catalysts interact with chemical substances and induce reaction of these substances, without themselves being converted. They are commonly divided into heterogeneous catalysts (solids that are not soluble in the reaction media), and homogeneous catalysts (which are miscible or soluble in the reaction media). Adsorbents are solid materials that interact with chemical substances in a gas or liquid phase, but do not chemically convert these substances. They are typically used in separation processes, for example to remove impurities. Catalysts and adsorbents are closely related because they share similar surface properties, and are often manufactured by the same companies.

Cleaning Agents and Toiletries

The Cleaning Agents and Toiletries category comprises establishments which are primarily engaged in the production of:

Soaps (solid or liquid),

Coatings/adhesives which are very specific to a particular niche market are located in various categories throughout ODP, and are linked from the By_Application category.

Conferences

Conferences, trade shows, and conventions for the chemical industry and its customers.

Custom Manufacturing

Custom manufacturers of chemicals, also called tollers, make use of general-purpose equipment to meet chemical manufacturing needs of their customers. They are often called upon during the development stage of a product cycle, when less than full-scale production is required for demonstration purposes. However, the arrangement may also be longer or indefinite, when a toller has production capabilities that its customer does not have and wishes to permanently outsource. Many chemical companies engage in some custom manufacturing activities as part of their business model. Only companies for which this is a primary activity are listed in this category.

When submitting the website for a company, please use the official name of the company as the site''s title, and a brief objective description of its activities and capabilities as the site''s description.

Please submit only directories where the scope encompasses the chemical industry as a whole.

Directories where the scope is limited to a specific chemical industry sector (for example, a directory of plastics producers) should be submitted to the appropriate sub-sector category.

Diversified Manufacturers

Only manufacturers of a diverse range of chemicals with no particular specialty should be listed in this category. Whenever possible, sites for chemical companies should be listed instead in a more specific chemical sub-sector category which describes the primary focus of the company (and not necessarily its entire product line).
