Products classified under HTS 3824.92.00.00
Polyglycol Ester of Methylphosphonic Acid Flame Retardant
This is a specific polyglycol ester of methylphosphonic acid used as a flame retardant additive in polyurethane foams and plastics. It falls under HTS 3824.92.00.00 because it is explicitly classified as polyglycol esters of methylphosphonic acid, a chemical preparation not elsewhere specified. These compounds provide fire resistance by releasing non-flammable gases when exposed to heat.
Antifoam Additive Based on Polyglycol Methylphosphonate
An industrial antifoam agent composed of polyglycol esters of methylphosphonic acid for use in chemical manufacturing and wastewater treatment. Classified under HTS 3824.92.00.00 due to its specific chemical structure as polyglycol esters of methylphosphonic acid. It controls foam formation in processing by altering surface tension.
Polyglycol Methylphosphonate Plasticizer for Polymers
A plasticizing agent derived from polyglycol esters of methylphosphonic acid, used to enhance flexibility in PVC and other polymers. It is specifically covered by HTS 3824.92.00.00 as polyglycol esters of methylphosphonic acid preparations. This additive improves processability without compromising flame retardancy.
Fire-Resistant Coating Additive Polyglycol Phosphonate
A reactive additive for intumescent fire-resistant coatings, consisting of polyglycol esters of methylphosphonic acid. Falls under HTS 3824.92.00.00 for its precise chemical identity as polyglycol esters of methylphosphonic acid. It promotes char formation during fire exposure for protective expansion.
Polyglycol Methylphosphonate Hydraulic Fluid Stabilizer
Chemical stabilizer for synthetic hydraulic fluids based on polyglycol esters of methylphosphonic acid, enhancing thermal stability. Classified precisely under HTS 3824.92.00.00 as these specific esters. Prevents degradation in high-pressure fluid systems.
Phosphonate-Based Polyglycol Surfactant for Detergents
Specialty surfactant incorporating polyglycol esters of methylphosphonic acid for industrial detergent formulations. HTS 3824.92.00.00 applies directly to these named chemical esters used in cleaning preparations. Provides wetting and dispersing properties with flame retardant bonus.
Flame Retardant Concentrate 75% Polyglycol Phosphonate
High-concentration (75%) masterbatch of polyglycol esters of methylphosphonic acid for compounding into thermoplastics. Specifically named under HTS 3824.92.00.00 for these phosphonate esters. Enables efficient flame retardancy in injection molding applications.
