n-Butyl Methacrylate (High Purity Grade)
Ultra-high purity n-butyl methacrylate (>99.9%) used in optical resins and medical device coatings, distinguished from standard grades. Even though butyl esters have specific subheadings, this specialty grade falls under HTS 2916.14.20.50 'other' due to statistical reporting distinctions. Minimal impurities ensure clarity in final polymerized products.

Methyl Methacrylate Monomer
Methyl methacrylate (MMA) is the methyl ester of methacrylic acid, a clear liquid unsaturated acyclic monocarboxylic acid ester used primarily as a monomer in polymerization processes. It falls under HTS 2916.14.20.50 as an 'other' ester of methacrylic acid, distinct from butyl or isobutyl variants specified elsewhere. This chemically defined compound is essential for producing acrylic plastics and resins.
Ethyl Methacrylate
Ethyl methacrylate is an ester of methacrylic acid with an ethyl group, used in coatings, adhesives, and dental materials due to its reactivity. Classified under HTS 2916.14.20.50 as an 'other' methacrylic acid ester not specifically named. Meets Chapter 29 criteria as a separate chemically defined organic compound.
n-Propyl Methacrylate
n-Propyl methacrylate, the normal propyl ester of methacrylic acid, serves as a reactive diluent in radiation-curable inks and UV coatings. It qualifies for HTS 2916.14.20.50 as an unsaturated acyclic monocarboxylic acid ester outside named categories. The compound's double bond enables free-radical polymerization.
Isopropyl Methacrylate
Isopropyl methacrylate is a branched-chain ester of methacrylic acid used in specialty resins and contact lens materials. Falls under 'other' methacrylic esters in HTS 2916.14.20.50 due to its acyclic unsaturated structure. Provides lower viscosity than n-propyl analog for formulation flexibility.
2-Ethylhexyl Methacrylate
2-Ethylhexyl methacrylate, with its branched C8 chain, functions as a flexibility-modifying comonomer in acrylic emulsions for paints. Classified in HTS 2916.14.20.50 as an 'other' methacrylic ester due to complex alkyl structure. Low volatility suits exterior architectural coatings.
Cyclohexyl Methacrylate
Cyclohexyl methacrylate contains a cyclic alcohol moiety esterified with methacrylic acid, used in UV-curable adhesives and stereolithography resins. Despite cyclic substituent, classifies under acyclic acid esters HTS 2916.14.20.50 per Chapter 29 notes prioritizing acid classification. High Tg polymers result from its rigid ring structure.
