Products classified under HTS 2916.14.20
Methyl Methacrylate Monomer
Methyl methacrylate (MMA) is the methyl ester of methacrylic acid, a clear, volatile liquid used primarily in the production of acrylic polymers and resins. It falls under HTS 2916.14.20 as an 'other' ester of methacrylic acid, being an unsaturated acyclic monocarboxylic acid derivative. This chemically defined organic compound is essential for manufacturing PMMA plastics like Plexiglas.
Ethyl Methacrylate
Ethyl methacrylate is an ester of methacrylic acid used in coatings, adhesives, and specialty resins. As an unsaturated acyclic monocarboxylic acid ester, it qualifies under HTS 2916.14.20 'other' category per Chapter 29 note on ester classification by numerical order. The compound remains chemically defined without impurities affecting its primary classification.
Butyl Methacrylate
Butyl methacrylate, the butyl ester of methacrylic acid, serves as a reactive diluent in radiation-curable coatings and printing inks. It classifies under HTS 2916.14.20 as an 'other' methacrylic acid ester, adhering to Chapter 29 rules for unsaturated acyclic monocarboxylic acid derivatives. Its low volatility makes it suitable for industrial formulations.
2-Ethylhexyl Methacrylate
2-Ethylhexyl methacrylate is a branched-chain ester used in pressure-sensitive adhesives and elastomers. This 'other' methacrylic acid ester under HTS 2916.14.20 fits Chapter 29 as it's a separate chemically defined compound without excluded impurities. Its plasticizing properties enhance polymer flexibility.
Isobornyl Methacrylate
Isobornyl methacrylate, derived from methacrylic acid and isoborneol, provides hardness in UV-curable coatings and dental composites. Classified as 'other' under HTS 2916.14.20, it meets Chapter 29 criteria for cyclic alcohol esters of acyclic acids by later numerical order rule. Its high Tg enhances cured film properties.
2-Hydroxyethyl Methacrylate (HEMA)
2-Hydroxyethyl methacrylate (HEMA) is a functional monomer with both acrylate ester and hydroxyl groups, used in hydrogels and contact lenses. It falls under HTS 2916.14.20 as an 'other' methacrylic ester per Chapter 29 ester classification rules prioritizing acid-function heading. The compound remains a separate chemically defined organic compound.
Glycidyl Methacrylate
Glycidyl methacrylate (GMA) features an epoxide ring for crosslinking in powder coatings and composites. As a methacrylic acid ester derivative, it classifies under HTS 2916.14.20 'other,' compliant with Chapter 29 exclusion of epoxides only for ring-position heteroatoms. The ester function determines primary classification.
Ethylene Glycol Dimethacrylate (EGDMA)
Ethylene glycol dimethacrylate (EGDMA) is a difunctional crosslinking monomer for improved mechanical properties in resins. Though di-functional, it classifies as 'other' methacrylic ester under HTS 2916.14.20 since Chapter 29 prioritizes monocarboxylic acid ester heading. Used in dental composites and 3D printing resins.
n-Butyl Methacrylate
n-Butyl methacrylate is the straight-chain butyl ester used in low-odor architectural paints and clear coats. HTS 2916.14.20 'other' covers this pure methacrylic acid ester per Chapter 29 chemical definition. Provides good adhesion and flexibility in copolymers.
Lauryl Methacrylate
Lauryl methacrylate, C12 alkyl chain ester, used in comb polymers and lubricant additives. Classifies HTS 2916.14.20 as 'other' methacrylic ester, chemically defined per Chapter notes. Long chain reduces volatility for high-temperature applications.
Stearyl Methacrylate
Stearyl methacrylate (C18) provides hydrophobicity in wax-like polymers for personal care. HTS 2916.14.20 'other' per monocarboxylic ester priority. Solid at room temperature, melts ~25°C.
Tetrahydrofurfuryl Methacrylate
THFMA offers low viscosity and adhesion in 3D printing resins. Cyclic ether alcohol ester under 2916.14.20 by ester rule precedence.
Poly(ethylene glycol) Methyl Ether Methacrylate (PEGMA)
PEGMA (Mn 360-500) for biocompatible hydrogels. Oligoether ester still 2916.14.20 monomer.
Benzyl Methacrylate
Benzyl methacrylate for optical resins. Aromatic ester under 2916.14.20.
Tridecyl Methacrylate
C13 methacrylate for concrete admixtures. HTS 2916.14.20 'other'.
