Phenothiazine Inhibitors (PTZ)

WeylChem International’s phenothiazine (PTZ) inhibitors are one of the most commonly used polymerization inhibitors and reaction stabilizers in the world for manufacturing acrylic acid, methyl methacrylate, and a variety of other monomers, derivatives, and intermediates. These monomers and intermediates are used in the synthesis of polymers and chemical compounds which are frequently used in paints, coatings, water treatment processes, and home and personal care applications.

WeylChem International offers PTZ in prills and dissolved in an organic solvent. The prill format of PTZ offered here is a unique offering of the chemistry that provides better particle size uniformity that improves solubility in reaction mixtures. It also minimizes dusting, clumping, and physical space required for storage. These products are manufactured using reactors and equipment with maintenance procedures that minimize shutdown frequency and downtime and can be packaged in various formats with flexibility depending on each facility’s requirements.

The phenothiaizine inhibitors that WeylChem International manufactures provides inhibition at very low concentrations through its mechanism as a radical scavenger that can be used in high temperatures and in anoxic reaction conditions. These products also offer additional functionality as an antioxidant and shortstopping agents. In synthetic lubricant and oil manufacturing for example, it may be used as an antioxidant to prolong the service life of piston-driven engine oils and compressor and fluid-flow lubricants. When used in chloroprene production applications, it helps to control molecular weight as a shortstopping agent and provides storage and transportation stability.
