Effective Polymerization Inhibitor

4-Hydroxy TEMPO is highly efficient in preventing undesired polymerization reactions, making it indispensable for monomer storage and industrial processing. Its stable free radical nature ensures consistent inhibition of radical-initiated polymerization, safeguarding raw materials from premature solidification, especially in the plastics and coatings industries.

Safe Handling and Regulatory Compliance

Classified as non-poisonous and non-hazardous for transport, 4-Hydroxy TEMPO is not regulated as dangerous goods and is compliant with international industrial safety standards. Its low bioaccumulation potential and stable properties minimize environmental and workplace risks when used and stored as recommended.

FAQ's of 4-Hydroxy TEMPO / Polymerization Inhibitor 701:

Q: How is 4-Hydroxy TEMPO used as a polymerization inhibitor?

A: 4-Hydroxy TEMPO works by neutralizing free radicals that can trigger unwanted polymerization, especially in monomers like styrene, acrylates, and methacrylates. Simply add the required amount to the monomer before or during storage and processing to ensure effective inhibition.

Q: What benefits does 4-Hydroxy TEMPO offer compared to other inhibitors?

A: 4-Hydroxy TEMPO provides reliable and long-lasting inhibition due to its stable free radical structure. It remains effective even at elevated temperatures, acts as an antioxidant, and is compatible with most plastics and organic solvents, making it a versatile choice for various industrial applications.

Q: When should 4-Hydroxy TEMPO be added during the process?

A: For optimal results, 4-Hydroxy TEMPO should be introduced to monomers immediately after production or prior to storage and transportation. This ensures continuous protection against premature polymerization throughout the supply chain and processing stages.

Q: Where should 4-Hydroxy TEMPO be stored for maximum shelf life?

A: Store 4-Hydroxy TEMPO in tightly sealed containers in a cool, dry, and well-ventilated area, away from heat and direct light. Under these conditions and in original packaging, the product maintains its efficacy for up to 24 months.

Q: What is the compatibility of 4-Hydroxy TEMPO with other materials?

A: 4-Hydroxy TEMPO is compatible with most plastics and organic solvents, such as ethanol, acetone, and chloroform. However, it should be kept away from strong oxidizing agents and acids to preserve its stability and functional properties.

Q: How is 4-Hydroxy TEMPO manufactured and supplied?

A: It is produced via chemical synthesis and shipped in either 25 kg fibre drums or 1 kg bottles. As a major manufacturer and exporter in India, the supplier ensures the product meets high purity and safety standards.

Q: What makes 4-Hydroxy TEMPO environmentally safe?

A: The compound has a low environmental impact, is not expected to bioaccumulate, and is considered non-poisonous, making it a more sustainable option for industrial use.
