Description

2-(2-Hydroxyethoxy)Ethyl 2-Hydroxypropyl 3,4,5,6-Tetrabromophthalate is a specialized brominated phthalate ester derivative, functioning as a highly effective reactive flame retardant and plasticizer. Its molecular structure is engineered to provide excellent flame retardancy while maintaining compatibility with various polymer matrices, particularly in flexible PVC and polyurethane systems. This compound is essential for manufacturers in the wire & cable, construction materials, and textile coating industries seeking to enhance fire safety without compromising material flexibility or processing characteristics.

Application

• Primary Flame Retardant for Flexible PVC: Used in the production of fire-resistant cables, wires, flooring, and wall coverings.
• Reactive Modifier in Polyurethane Foams: Imparts flame retardancy to flexible and rigid foams used in insulation, furniture, and automotive interiors.
• Additive for Synthetic Polymers: Enhances fire resistance in coatings, adhesives, sealants, and elastomers (CASE) applications.
• Textile Back-Coating: Applied to fabrics for upholstery, curtains, and protective clothing to meet stringent flammability standards.
• Electronic Encapsulants: Used in potting compounds and encapsulating materials to protect electronic components from fire risks.
• Composite Materials: Incorporated into fiber-reinforced plastics and other composites for construction and transportation sectors.
