Bio-1,5-Pentanediol Diacrylate comes from renewable raw materials and steps into the scene as a multifunctional acrylate monomer. Labs see it in work as a bridge between sustainable chemistry and industrial progress. This molecule attracts attention, not just for being a sustainable alternative, but for the performance it unlocks. With its origins grounded in bio-based sources, Bio-1,5-Pentanediol Diacrylate brings a clear edge over conventional petro-based options. Its HS Code tracks as 2916129000, keeping trade and compliance specialists satisfied.
This diacrylate's molecular formula reads C11H16O4, and its structure lines up as two acrylate groups joined to a pentanediol backbone. The diacrylate architecture lets it introduce extra crosslinking points in resins and polymers, boosting their mechanical strength. Each molecule: two acrylate (CH2=CHCOO-) ends anchored by a 1,5-pentanediol core. As a result, it's ready to participate fully in free-radical polymerization, creating networks that affect both flexibility and toughness.
Bio-1,5-Pentanediol Diacrylate wears a lot of hats in terms of format. Most often sold as a clear, colorless liquid, you might spot it labeled by some distributors as a low-viscosity crystal or see it listed in catalogs as a solution for easy in-situ mixing. It shows a density near 1.09 g/mL at 25°C, fitting right into the expectations for acrylate monomers. It rarely forms flakes or powder at standard storage temperatures, but cold or unstable storage conditions could sometimes shift appearance. Chemists favor the low volatility and manageable viscosity, with numbers showing a viscosity in the range of 20-40 mPa·s at 25°C. This means it handles well by pump or in batch mixing, avoiding clogs or unpredictable flows. The melting point sits below room temperature, so you won't see it turning solid during regular use.
This diacrylate thrives where the need for biocompatibility, sustainability, and solid end-product performance cross paths. It checks off the need for clarity, stability against yellowing, and low odor. The purity usually clocks above 98%, supporting consistency across batches. Molecular weight tips in at about 212.24 g/mol. This matters most in areas where formula precision drives reliable curing during UV polymerization. Customers look for specifications calling out inhibitor content, since acrylates run the risk of premature polymerization. A stabilized grade typically contains 100-150 ppm of MEHQ or similar antioxidants.
Formulators in coatings, adhesives, and ink industries swear by Bio-1,5-Pentanediol Diacrylate for its role in creating robust, flexible, and more sustainable films. It excels in UV-cured systems, where speed, toughness, and environmental responsibility come together. I've seen product engineers move to this monomer to dial in balance between hardness and flexibility, useful for protective coatings that need to resist cracking but remain flexible. The liquid format encourages integration with other acrylates, urethanes, and reactive diluents, unlocking a wider processing window in both automated and manual setups.
This chemical, much like other acrylates, can irritate the skin, eyes, and respiratory tract. It calls for gloves and goggles, and should not be inhaled or allowed prolonged contact with skin. Safety Data Sheets flag it as potentially harmful if mishandled, especially in bulk operations or situations without proper ventilation. Proper storage means cool, dark, well-ventilated spaces away from heat or open flames, since acrylates can build up dangerous pressure in sealed containers under heat. Regulations treat it as both a chemical and hazardous material, with labeling, hazard statements, and emergency measures a must for both shipping and workplace handling.
More industries turn their attention to raw materials. Bio-1,5-Pentanediol Diacrylate, born from biobased feedstocks, reduces reliance on crude oil derivatives. This shift supports lifecycle improvements for larger supply chains. Brands feel pressure to improve environmental reports and meet stricter global REACH regulations. Seeing this monomer in action gives manufacturers a tangible step toward greener production. A reliance on sugar-based or plant-derived pentanediol changes long-term planning, shrinking the environmental impact of large-scale polymer networks. Moving forward, scale-up and cost still challenge new monomers like this, but demand keeps growing stronger as green chemistry becomes non-negotiable.
