Storage
NPS(SPS) is not combustible but assists combustion materials due to release of oxygen.Provided it is stored under appropriate condition.It must be stored dry in closed containers and protected from direct sunlight,heat and humidity.Impurities such as dirt,rust or traces of metal and reductants may cause catalytic decomposition.The product as supplied or in solution needs to be handled with appropriate care.The eye,skin and clothes must be protected when working with NPS(SPS) as damp powder or aqueous solution has a bleaching and slightly corroding effect.
Application
Polymerization : Initiator for the emulsion or solution Polymerization of acrylic monomers,vinyl acetate,vinyl chloride etc.and for the emulsion co-polymerization of styrene,acrylonitrile,butadiene etc.
Metal treatment : Treatment of metal surfaces(e.g. in the manufacture of semiconductors;
cleaning and etching of printed circuits),activation of copper and aluminium surfaces.
Cosmetics : Essential component of bleaching formulations.
Paper : modification of starch,repulping of wet - strength paper.
Textile : Desizing agent and bleach activator - particularly for cold bleaching.(i.e.bleaching of Jeans).
Others :
- Chemical synthesis
- Water treatment(decontamination)
- Waste gas treatment,oxidative degradation of harmful substances(e.g.Hg)

Paraformaldehyde is a polymer of formaldehyde with the chemical formula (CH2O)n, where n is typically in the range of 8 to 100. It is a white, crystalline solid composed of small, polymeric formaldehyde units. Paraformaldehyde is commonly used as a solid form of formaldehyde, and it has various applications in different fields.
Form and Structure:
Paraformaldehyde is a low-molecular-weight polymer of formaldehyde, consisting of repeating CH2O units.
It is often produced in the form of white, crystalline granules or as a powder.
Uses:
Fixative in Histology: Paraformaldehyde is commonly used in histology and pathology laboratories as a fixative for preserving biological specimens for microscopic analysis.
Disinfectant: It has disinfectant properties and can be used for sterilizing equipment.
Crosslinking Agent: Paraformaldehyde is used in the crosslinking of proteins, peptides, and nucleic acids in molecular biology applications.
Chemical Synthesis: It serves as a source of formaldehyde in various chemical reactions and syntheses.
Handling and Safety:
Paraformaldehyde should be handled with care, and precautions should be taken to avoid inhalation, skin contact, or ingestion.
When paraformaldehyde is heated, it releases formaldehyde gas, which is a strong irritant. Adequate ventilation and protective equipment should be used when working with paraformaldehyde.
Dissolution:
To use paraformaldehyde as a fixative or in other applications, it is typically dissolved in water to generate a formaldehyde solution.
Storage:
Paraformaldehyde should be stored in a cool, dry place away from heat sources and incompatible materials.
Formalin is a solution of formaldehyde gas dissolved in water. Formaldehyde is a colorless, strong-smelling gas that is commonly used in a liquid form, as formalin, for various industrial applications. Here are some key points about formalin:
Chemical Composition: Formalin is typically a 37% aqueous (water-based) solution of formaldehyde. The remaining percentage is water.
Uses:
Preservation: Formalin is widely used as a preservative for biological specimens. It helps to prevent decay and decomposition, making it essential in laboratories, museums, and medical facilities for preserving tissues and specimens.
Disinfectant: It has antimicrobial properties, and as such, formalin solutions are sometimes used as disinfectants and biocides.
Textile Industry: Formalin can be used in the textile industry for wrinkle-resistant finishes on fabrics.
Health and Safety Concerns:
Formalin is a strong irritant and can be harmful if inhaled, ingested, or comes into contact with the skin.
Prolonged or repeated exposure to formaldehyde can cause respiratory irritation and may be associated with certain health risks.
Proper ventilation and personal protective equipment are recommended when working with formalin.
Regulation:
Due to its potential health risks, the use and handling of formalin are subject to regulations and guidelines in many countries. These regulations aim to ensure safe practices and protect workers and the environment.
