Paraformaldehyde, also known as PFA, is the linear polymer of formaldehyde, typically appearing as a white solid powder or granules. It does not have a fixed melting point but depolymerizes upon heating within a certain temperature range, releasing gaseous formaldehyde. Compared to formaldehyde aqueous solution (formalin), Paraformaldehyde offers significant advantages such as high purity, extremely low water content, good stability, and ease of transportation and storage. It serves as an important and convenient “solid formaldehyde” source.It is also a chemical intermediate in modern chemical production.Paraformaldehyde is mainly used in biological research as a fixative.It preserves tissue and cell structures for microscopy. Industrially, it serves as a crucial raw material for manufacturing synthetic resins and plastics. Additionally, it functions as a disinfectant and fumigant,

Caustic Soda, also known as Sodium Hydroxide, is one of the most fundamental strong bases and a critical inorganic chemical raw material. At room temperature, the pure product is a white, opaque solid, commonly available in flakes (flake caustic), pearls (granular), blocks, and also as a high-concentration liquid (liquid caustic). It is highly hygroscopic and corrosive, readily dissolving in water with significant heat release. As a bulk basic chemical, caustic soda is the “staple food” of modern industry, and its production and consumption are key indicators of a nation's chemical industry level. It is widely used in almost all core industrial fields such as the chemical industry, textile, papermaking, metallurgy, daily chemicals, and water treatment.

Tetrachloroethylene, also known as perchloroethylene or 1,1,2,2-tetrachloroethane, is a colorless, non-flammable liquid with a sharp, ether-like odor and the chemical formula C₂Cl₄. Its CAS number is 127-18-4, and its UN number is 1897. Tetrachloroethylene is widely used in the dry cleaning industry highly effective in removing grease and stains from fabrics. It also serves as a metal degreasing agent in industrial processes, capable of dissolving stubborn lubricants and contaminants from metal surfaces. Additionally, it finds applications in the production of fluorocarbons (such as refrigerants) and as a component in certain paint removers and cleaning solutions. In addition, it is also used in chemical synthesis and intermediates, medicine, and other industries.

Sodium laureth sulfate, an accepted contraction of sodium lauryl ether sulfate, also known as SLES, is used in many personal care products (soaps, shampoos, toothpaste, etc.) and for industrial uses. SLES is an inexpensive and very effective foaming agent. SLES, sodium lauryl sulfate (SLS), ammonium lauryl sulfate (ALS), and sodium pareth sulfate are surfactants that are used in many cosmetic products for their cleaning and emulsifying properties. It is derived from palm kernel oil or coconut oil. In herbicides, it is used as a surfactant to improve absorption of the herbicidal chemicals and reduces the time the product takes to be rainfast when enough of the herbicidal agent will be absorbed.

DMF is an organic compound with the formula (CH3)2NC(O)H, which is a colorless liquid that is miscible with water and most organic liquids. Dimethylformamide is miscible with water and the majority of organic liquids. DMF is a common solvent for chemical reactions. Dimethylformamide is odorless, but technical-grade or degraded samples often have a fishy smell due to the impurity of dimethylamine.

Butyl Acrylate is an organic compound with the formula C4H9O2CCH=CH2. A colorless liquid, it is the butyl ester of acrylic acid. It is used commercially on a large scale as a precursor to polybutylacrylate, which is used in paints, sealants, coatings, adhesives, fuel, textiles, plastics, and caulk.
