Highly Active Calcium Hydroxide

Introduction:

Polyether polyols are key components used in the production of polyurethanes.
Polyether-based polyurethanes exhibit enhanced hydrolytic stability and excellent resistance to weak acids and bases compared to polyester-based polyurethanes.
Polyether polyurethane can be divided into soft foam polyether, rigid foam polyether, and elastomer with polyether according to the performance of polyether products.
However, polyether-based polyurethanes are more susceptible to UV radiation and provide poor resistance to oils and fuels compared to polyester-based polyurethanes.
Application:
Polyether polyols' major use is in polyurethane foams. Flexible foams are primarily used in cushioning applications such as furniture, bedding and car seats, and in carpet underlay. Rigid foam's largest consumer is the construction industry where it is mostly used for insulation. Rigid foam is also used in commercial refrigeration and packaging. Smaller uses for polyether polyols include elastomers, adhesives and sealants, surface coatings and polyurethane fibres.

HiraChem is your specialist supplier of Sodium Hydroxide.
Sodium Hydroxide (Caustic Soda ) 98-99% Flakes.

Sodium Hydroxide, also known as lye and caustic soda, is an inorganic compound with formula NaOH. It is a white solid, a salt (ionic compound), consisting of sodium cations Na+ and hydroxide anions OHâ??. Sodium hydroxide is a highly caustic base and alkali, that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. It is highly soluble in water and readily absorbs moisture and carbon dioxide from the air. It forms a series of hydrates NaOH·nH2O. The monohydrate NaOH·H2O cystallizes from water solutions between 12.3 and 61.8 C. The commercially available "sodium hydroxide" is often this monohydrate, and published data may refer to it instead of the anhydrous compound

Physical and chemical properties Calcium hydroxide (calcium hydroxide), an inorganic compound, chemical formula Ca(OH)2, commonly known as slaked lime or hydrated lime. It is a white powdery solid. After adding water, it presents two layers, the upper aqueous solution is called clear lime water, and the lower suspension is called lime milk Chemicalbook or lime slurry. The upper clear liquid clear lime water can be used to test carbon dioxide, and the lower turbid liquid lime milk is a building material. The solubility of calcium hydroxide decreases with increasing temperature. It is insoluble in alcohol, soluble in ammonium salts and glycerol, and can react with acid to generate corresponding calcium salts. At 580â??, it decomposes into calcium oxide and water
Calcium hydroxide is a strong base with bactericidal and antiseptic capabilities, and has a corrosive effect on skin and fabrics. However, due to its low solubility, the degree of harm is not as great as strong bases such as sodium hydroxide. Calcium hydroxide is widely used in industry. It is a commonly used building material, and is also used as a bactericide and chemical raw material.

Used in the manufacture of bleaching powder, water softener, depilatory, disinfectant, antacid, astringent and various calcium salts. Used in the inspection of carbon dioxide, gas absorption. Leather depilation, insecticide, water treatment.

Water chemical

Calcium chloride is a white crystalline chemical compound with the formula CaCl2, widely used for its versatile properties in various industries. It is a highly hygroscopic substance, meaning it readily absorbs moisture from the air, making it effective for dust control on roads and as a de-icing agent to prevent the formation of ice on roadways in cold climates. Calcium chloride also finds application in the food industry as a food additive, primarily as a firming agent in canned vegetables and as a calcium source in certain food products. In addition to its industrial and culinary uses, it is employed in concrete production to accelerate the setting time of cement and in drilling fluids for oil and gas well drilling. Its ability to control moisture, lower freezing points, and serve as a calcium supplement underscores its importance across multiple sectors.

Calcium hydroxide is used in industrial settings, such as a flocculant and to raise the pH of the water , it is also used as an intermediate in paper production and in the manufacturing of cements, mortars and plasters. It is also used as an accelerant in processes for the production of synthetic rubber and plastics. Calcium Hydroxide is also used in the manufacture of paints and waterproof coatings and as an additive to lubricants and oil drilling fluids, to improve the viscosity of the fluids.
