    Acrylate series

  • Describe

    Polyethylene glycol diacrylate (PEGDA) is a type of bifunctional acrylate monomer/oligomer prepared by esterification reaction of polyethylene glycol (PEG) with acryloyl chloride or acrylic acid. It has excellent hydrophilicity, flexibility and biocompatibility.

Physical and chemical properties

  • 1. Chemical Identity
    • Chemical Name: Poly(ethylene glycol) diacrylate
    • Synonyms: PEGDA, Polyethylene glycol (n) diacrylate
    • CAS Number: 26570-48-9 (This is a general CAS for the polymer class)
    • Molecular Formula: H2​C=CHCO(OCH2​CH2​)n​OOCCH=CH2​ (where 'n' varies)
    • Molecular Weight: Variable (Typically ranges from ~300 to >1000 g/mol)
  • 2. Physical Properties (Representative Example: PEG 400 Diacrylate)
    • Appearance: Clear, colorless to pale yellow liquid.
    • Odor: Mild, characteristic, ester-like.
    • Melting Point: Not applicable (amorphous solid at low temperatures).
    • Boiling Point: >200 °C (>392 °F) at 1013 hPa
    • Density: Approximately 1.11 - 1.12 g/cm³ at 25 °C
    • Solubility:
    • In Water: Soluble (solubility decreases as molecular weight increases).
    • In Organic Solvents: Soluble in many common organic solvents like acetone, ethanol, and THF.
    • Vapor Pressure: <0.01 hPa at 20 °C
    • Viscosity: 50 - 100 mPa·s at 25 °C (Highly dependent on molecular weight)
  • 3. Chemical Properties and Stability
    • Stability: Stable under recommended storage conditions. Typically supplied with a polymerization inhibitor (e.g., MEHQ).
    • Incompatibilities: Incompatible with strong oxidizing agents, strong bases, strong acids, reducing agents, peroxides, and free-radical initiators. Avoid exposure to UV light and high temperatures.
    • Hazardous Polymerization: May occur if not properly inhibited or if exposed to heat, light, radiation, or contaminants. Polymerization is a highly exothermic reaction and can be rapid and violent.
    • Hazardous Decomposition Products: Combustion may produce toxic fumes of carbon monoxide (CO) and carbon dioxide (CO2​).
  • 4. Other Key Data
    • Flash Point: >150 °C (>302 °F) - Closed cup
    • Refractive Index (n20/D): ~1.465 - 1.470

Safety Information

  • This information is a summary based on the Globally Harmonized System of Classification and Labelling of Chemicals (GHS).
  • 1. GHS Classification
    • Skin Irritation (Category 2)
    • Serious Eye Irritation (Category 2A)
    • Skin Sensitization (Category 1)
    • Hazardous to the Aquatic Environment, Chronic Hazard (Category 3)
  • 2. GHS Label Elements
    • Pictogram:
      • Exclamation Mark (GHS07)
    • Signal Word: Warning
    • Hazard Statements (H-Statements):
      • H315: Causes skin irritation.
      • H317: May cause an allergic skin reaction.
      • H319: Causes serious eye irritation.
      • H412: Harmful to aquatic life with long lasting effects.
    • Precautionary Statements (P-Statements):
    • Prevention:
      • P261: Avoid breathing dust/fume/gas/mist/vapors/spray.
      • P272: Contaminated work clothing should not be allowed out of the workplace.
      • P273: Avoid release to the environment.
      • P280: Wear protective gloves, eye protection, and face protection.
    • Response:
      • P302 + P352: IF ON SKIN: Wash with plenty of soap and water.
      • P305 + P351 + P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.
      • P333 + P313: If skin irritation or rash occurs: Get medical advice/attention.
      • P337 + P313: If eye irritation persists: Get medical advice/attention.
      • P362 + P364: Take off contaminated clothing and wash it before reuse.
    • Storage:
    • Store in a cool, dark, well-ventilated place away from incompatible materials.
    • Disposal:
      • P501: Dispose of contents/container to an approved hazardous waste disposal plant.
  • 3. Summary of Primary Hazards
    • Health Hazards: Causes irritation to the skin and serious irritation to the eyes. It is a potent skin sensitizer, meaning that repeated or prolonged contact can lead to the development of a severe allergic skin reaction (allergic contact dermatitis).
    • Environmental Hazards: Harmful to aquatic life with long-lasting effects. Release into the environment should be avoided.
    • Reactivity Hazards: The product is a reactive monomer that can undergo hazardous polymerization if not properly stabilized and handled. Keep away from heat, sunlight, and contamination. Check inhibitor levels periodically if storing for long periods.
