In the demanding world of chemical manufacturing, particularly in the production of polymers, ensuring the stability of monomers is paramount. Uncontrolled polymerization can lead to significant financial losses, safety hazards, and compromised product quality. This is where polymerization inhibitors play a crucial role. As a leading manufacturer and supplier of specialty chemicals, NINGBO INNO PHARMCHEM CO.,LTD. understands the critical need for reliable monomer stabilization. This article delves into the importance of polymerization inhibitors and highlights our high-purity offerings.

Monomers, the fundamental building blocks of polymers, are often highly reactive. Factors like heat, light, or even trace impurities can trigger self-polymerization, leading to the formation of unwanted polymers. This premature polymerization can result in process disruptions, equipment fouling, and the generation of off-spec products. To combat these risks, specialized chemical additives known as polymerization inhibitors are employed.

One of the most effective and widely used polymerization inhibitors is 4-Hydroxy-2,2,6,6-tetramethyl-piperidinooxy, commonly known as Inhibitor 701 or 4-Hydroxy-TEMPO, with CAS number 2226-96-2. This advanced free radical inhibitor offers superior performance compared to older chemistries like phenols and aromatic amines. Its unique molecular structure allows it to effectively scavenge free radicals, thereby halting or significantly slowing down the polymerization chain reaction.

Our role as a manufacturer means we are committed to delivering Inhibitor 701 with exceptional purity, typically ≥99%. This high purity is vital for its effectiveness in a wide range of applications, including the stabilization of olefin monomers such as ethylene and propylene, as well as acrylates, methacrylates, acrylonitrile, styrene, and butadiene. By preventing self-polymerization during production, separation, refining, storage, and transportation, our product ensures that your monomers remain stable and usable until they are intentionally polymerized under controlled industrial conditions.

For businesses looking to secure a reliable supply of this critical chemical intermediate, partnering with an established manufacturer and supplier is key. We offer competitive pricing and can cater to bulk orders, ensuring that your production lines are never interrupted due to monomer instability. Whether you are in the petrochemical sector, involved in organic synthesis, or require specialized solutions for monomer purification, our 4-Hydroxy-2,2,6,6-tetramethyl-piperidinooxy is the solution you need. We invite you to contact us to inquire about pricing and to request a sample of our high-quality Inhibitor 701.
