Product Inspection → 5. Packaging Acrylation: Ethylene oxide reacts with acrylic acid in the presence of an inhibitor and a catalyst under strict temperature (60–80°C) and pressure controls. Continuous stirring ensures uniform molecular formation. Separation: By-products (water and trace impurities) are separated via phase partition and centrifugation. Purification: Multi-stage vacuum distillation raises product purity >99.5%. Inspection: Batch testing for acid value, residual monomer, color index (APHA), and presence of inhibitors, compliant with ISO 9001 and ANSI Z124 standards. Packing: Typically in 200kg drums or 1000L IBC totes, nitrogen blanketed to prevent premature polymerization. *Entire production run is monitored via SCADA automation and ISO-certified management systems for traceability and reproducibility.

A: The main difference is the hydroxyalkyl side chain; HEA has a two-carbon hydroxyethyl group, while HPA has a three-carbon hydroxypropyl group. This changes hydrophilicity, reactivity, and glass transition temperature properties—HEA generally provides higher crosslink density, making it ideal for coatings and hydrogels. Q2: Which international standards should 2 hydroxyethyl acrylate meet for use in biomedical applications? A: Products should comply with FDA 21 CFR 177 , ISO 10993 (biocompatibility) , and be free from toxic impurities such as ethylene oxide residue. Always request a Certificate of Analysis and biocompatibility report. Q3: What shelf life and storage recommendations apply to 2 hydroxyethyl acrylate? A: Typically, 12 months from date of manufacture in sealed, UV-protected container111s, stored at 5–25°C. Nitrogen blanketing and inhibitor content (>180 ppm MEHQ) are essential to prevent spontaneous polymerization. Q4: How can I determine the right inhibitor level for my application? A: Most 2 hydroxyethyl acrylate is stabilized with 180–220 ppm MEHQ (monomethyl ether hydroquinone). For UV applications, ensure ≤50 ppm for higher reactivity; for bulk storage, 200 ppm is safer. Always specify during procurement. Q5: Is 2 hydroxyethyl acrylate suitable for contact with drinking water? A: Only if the final polymer is fully cured and tested to ANSI/NSF 61 . Raw HEA is corrosive and not suitable for potable water systems. Confirm with supplier test data before deployment. Q6: What is the typical viscosity, and how does it impact application? A: Viscosity of HEA is about 7 mPa·s at 25°C—low enough for easy handling and rapid mixing in resin blends. Low viscosity favors fast diffusion in UV/EB formulations and high composite uniformity. Q7: What certifications do leading suppliers offer for export markets? A: CAS 818 61 1 supplied by certified companies usually comes with ISO 9001/14001 , REACH , RoHS , GMP (for pharma grades), and can be supplied with SGS or Bureau Veritas inspection.
