Industrial Applications of Ethylene dimethacrylate
| Industry | Applications | Process |
|---|---|---|
| Dental Materials | Dental restorative resins, dental filling materials, denture base resins | Serves as a crosslinking monomer in free-radical polymerization or UV-curing reactions |
| Polymer Industry | Acrylic resins, unsaturated polyester resins, ABS resins, PVC modifiers | Acts as a comonomer or crosslinker to form a network structure during polymerization or grafting |
| Rubber Industry | Modifiers for synthetic rubbers (e.g., styrene-butadiene rubber, nitrile rubber) | Functions as a crosslinker during vulcanization or polymerization to enhance hardness and abrasion resistance |
| Coatings & Inks | UV-curable coatings, optical fiber coatings, screen printing inks | Used as an active diluent or crosslinker for rapid curing under UV irradiation |
| Adhesives | Structural adhesives, pressure-sensitive adhesives | Participates in free-radical polymerization to impart bonding strength and solvent resistance |
| Composites | Fiberglass-reinforced plastics (FRP), sheet molding compounds (SMC) | Serves as a crosslinking component to increase crosslink density and heat resistance of the resin matrix |
| Optics & Electronics | Photoresists, lens materials, anti-reflective coatings | Enables precision patterning or material shaping via photopolymerization |
| Ion Exchange Resins | Production of strong-acid or weak-base ion exchange resins | Acts as a crosslinker to synthesize polymeric matrices with defined network structures |
| Plastic Modification | Modification of polyolefins (e.g., PE, PP) | Incorporated during reactive extrusion or grafting to improve thermal performance and mechanical strength |
Manufacturing Quality Control of Ethylene dimethacrylate
| Test Item | Common Testing Method | Method Summary |
|---|---|---|
| Purity | Gas Chromatography (GC) | Separates sample components by gas chromatography and quantitatively analyzes the content of the main component EGDMA using an FID or MS detector to evaluate purity. |
| Acid Value | Acid-Base Titration | Uses phenolphthalein as an indicator and titrates free acids in the sample with a standard potassium hydroxide ethanol solution to calculate the acid value (mg KOH/g). |
| Moisture Content | Karl Fischer Method | Utilizes the quantitative reaction between Karl Fischer reagent and water to determine trace moisture in the sample by coulometric or volumetric methods. |
| Color | Visual Color Comparison or Platinum-Cobalt (Pt-Co) Color Scale | Compares the sample with standard color solutions to assess color intensity, reflecting the level of impurities or oxidation. |
| Refractive Index | Abbe Refractometer Method | Measures the refractive index of the sample against sodium light (589.3 nm) at a specified temperature, used as an auxiliary indicator for purity or compositional consistency. |
| Density | Densimeter or Pycnometer Method | Determines the density of the sample at a standard temperature (e.g., 20°C), serving as one of the physical property control parameters. |
| Inhibitor Content (e.g., HQ, MEHQ) | High-Performance Liquid Chromatography (HPLC) | Uses reversed-phase HPLC to separate and quantify polymerization inhibitors (e.g., monomethyl ether of hydroquinone) added to the sample. |
| Residual Volatile Organic Compounds | Headspace-Gas Chromatography (HS-GC) | Analyzes residual solvents or other volatile impurities using headspace sampling coupled with GC. |
| Appearance | Visual Inspection | Observes whether the sample is a colorless to pale yellow transparent liquid, checking for suspended particles, precipitates, or turbidity. |
| Viscosity | Rotational Viscometer Method | Measures the dynamic or kinematic viscosity of the sample at a specified temperature, reflecting molecular weight distribution or tendency to polymerize. |
