What is a Chemical?

A chemical substance refers to any organic or inorganic substance with a specific molecular identity, including: (1) any substance wholly or partly produced by the result of a chemical reaction or any naturally occurring substance; (2) any element or non-combined Atoms. Chemical substances include elements, compounds (including additives, impurities), by-products, reaction intermediates and polymers. It does not include mixtures, products (agents), or articles.

Global consumption of flame retardant chemicals in 2012 was 3.9 billion pounds, and it is forecasted to reach 4 billion pounds in 2013. Guanyan World predicts that consumption will increase at a compound annual growth rate (CAGR) of 5% by 2018 and reach 5.2 billion pounds.
According to the National Fire Protection Association (NFPA), the cost of a fire in the United States is defined as the loss of fire and the amount of fire prevention, efforts to prevent the greatest loss by preventing fires, and prompt fire action when a fire actually occurs Generic term. Its cost was US $ 363 billion in 2012, and it is generally forecast to climb from 2.5% of GDP (total domestic production) to 3.0%.
Government regulations require manufacturers to use flame retardant chemicals on a wide range of everyday products. But the irony is that most of these chemicals used to prevent the loss of life and property caused by fires will have adverse effects on the environment. This market is introducing new technologies to find ways to convert these products into more environmentally friendly materials. It is expected that the market share will expand in the next five years.
A typical system for chemical substance risk management is the chemical substance review system. After the PCB contamination event in 1968, Japan passed the Chemical Substances Review Act (hereinafter referred to as the "Chemical Examination Act") in 1973, requiring a pre-examination system for all new chemical substances when manufacturing or importing them. Without safety confirmation, it is prohibited to make or import in Japan. After review, if the chemical is found to be as difficult to decompose, accumulate (accumulate in the body) and chronic toxicity (long-term continuous, trace intake will harm human health) as PCBs, it will be designated as "specific chemical ", Adopting a licensing system for manufacturing and import, strictly restricting use and requiring users to submit declarations. At the beginning of the formulation of this law, the characteristics of harmfulness management were relatively obvious, but after many revisions, the characteristics of its risk management became increasingly prominent.
