Application:
  • Polymer Chemistry: Analysis of polymer synthesis using AIBN under various conditions, with emphasis on thermal initiation properties (Suriyanarayanan & Nicholls, 2019 ).
  • Influence of cyclodextrin on the UCST-and LCST-behavior of poly (2-methacrylamido-caprolactam)-co-(N, N-dimethylacrylamide): Explores the role of AIBN in copolymerization processes influencing polymer properties relevant to material science applications (Burkhart & Ritter, 2014 ).
  • Preparation and characterization of polyaniline microcapsule loaded with 2, 2′‐azobis (2‐methylpropionitrile) initiator and its controlled release: Demonstrates innovative applications of AIBN in microencapsulation techniques, targeting enhanced performance in adhesive industries (Zhang et al., 2022 ).

New Tariffs & Effects on Pricing

Tariff note: As we navigate the current environment of tariff surcharges and mid-year manufacturer price increases, we want to keep you informed. While we have avoided making specific decisions thus far, we anticipate that we will be forced to implement a cost adjustment policy to offset the fees we have already been absorbing. We are committed to transparency and moderation in this process.
