In an effort to aid in combating plastic contamination of waterways and landfills, Akina, Inc. has recently developed a biodegradable, self-crosslinking resin. Intellectual property protection on the background technology for Nuplon was filed by Akina, Inc. with a priority date of June 25, 2020 and patent protection is currently pending under filing number US 2021070743. Akina, Inc. is actively seeking a partner interested in end-product applications for the Nuplon material. To that end, we’re putting Nuplon in the hands of the smartest people we know.
Starting from July, 2021, samples of “pour-and-cure” heat-curable Nuplon resin are free to request from the website (https://akinainc.com/polyscitech/products/NuPlon/index.php) with only cost being shipping charges for USPS shipping. Additionally, on any order simply type “Nuplon” into the “Special Instructions” section to receive your free sample.
Description: Prepolymer is a set of low molecular weight oligomeric esters comprised of varying lengths of lactides and other esters combined with multifunctional alcohols and multifunctional acids. Prepolymer is a viscous liquid (Brookfield spindle, 20 ⁰C, 1000 – 3000 cP). To cure: Pour solution into desired shape of mold or onto components. Nuplon has proven to be strongly adhesive so use of either PTFE, silicone rubber, or molds coated with mold-release aid is suggested to prevent adhesion. Heat in an oven at 150 – 170 ⁰C overnight (16-24 hours) to cure. Afterwards, demold product and cut/machine to form the final shape. Adhesion: Nuplon prepolymer has strong adhesive properties and may be used to attach two components together. For this simply clamp the pieces together with the Nuplon between them and cure as described above. Post-Cure Performance: Final product is optically clear, hard plastic. Mechanical: Elastic Modulus (0.1 – 1% strain): 4.8 + 1.6 MPa, Tensile Strength: 31.0 + 19.2 MPa, Extensibility: 5.3 + 1.6 % strain, Temperature stable up to 350 ⁰C when dry. Degradation: Under normal exposure to humidity in an indoor location (20 – 25C, 30 - 80% RH) product softens after about six months and degrades after about 1-2 years forming into a soft, gel. When hydrated, will quickly become flexible after a day or two and fully degrade to non-toxic products after 2-3 months in water.
