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.

TAIC is widely used as a coagent for peroxide crosslinking or radiation crosslinking of Chlorinated Polyethylene (CPE), EPDM, Fluroelaster and so on.TAIC is availavle for linking by x-ray, y-ray electron or ultra violet ray radiation and the product polyolefines have the superior insolubility to solvents and the tensile strength at high temperature could be improved.TAIC is effective modifier to heat resistance with increasing of crosslinking density for peroxide crosslinking denisty for peroxide crosslinking of CPE. Since TAIC acts as an acceptor of HCI which is envolved from CPE at crosslinking reaction and deteriorates its physical properties.TAIC is the most effective coagent for crosslinking EVA.TAIC preferably contributes to promote crosslinking rate and also to improve its heat resistance, compression set and abrasion resistance
1. Description: It is the raw material for making thermosetting resin, light curing epoxy resin coating, oil resistant coating and drying coating. Its copolymer emulsion is used for fiber finishing, fabric, leather and paper coating. Also used as wood, metal and other adhesives. 2. Typical recipes Used as crosslinked monomer in acrylic emulsion. The amount of carboxyl-containing acrylic emulsion pressure-sensitive adhesive is L % ~ 2% of the total monomer mass, and the initial adhesion will be greatly reduced if it exceeds 3%. For emulsion adhesives without carboxyl group, the general dosage is not more than 5%. The crosslinking reaction temperature of MMAM alone is high, generally 120 ~ 170�ºC, and the addition of protic catalyst can reduce the crosslinking temperature. Acrylic acid (AA) can both provide hydrogen protons and copolymerize with acrylates, so MMAM should be used as a composite crosslinking agent with AA at a dosage of 3:2. Cross-linking agent HA can replace N- hydroxymethyl acrylamide, and does not contain formaldehyde. 3. Application scope A. Can be used as crosslinking agent, widely used in fiber modified resin, processing dyes, plastic adhesives, soil stabilizers, etc. B. Used for fiber modification, resin processing, adhesives and paper, leather, metal surface treatment agent. Free samples 4. Storage and packaging A. All emulsions/additives are water-based and there is no risk of explosion when transported. B. This product can be packed in 25KG,50KG,200KG,1000KG plastic barrels. C. Store sealed in a cool, dry and ventilated place indoors. Before use, the container should be strictly sealed after each use. D. The product should be well sealed during transportation, moistureproof, alkali strong acid and rain water and other impurities mixed.
