Description

Polyethylenephthalate CAS NO 25610-19-9 is a high-performance polymer belonging to the polyester family, known for its excellent mechanical strength, thermal stability, and chemical resistance. This material is critical for applications demanding durability, dimensional stability, and barrier properties against gases and moisture. It is essential for manufacturers in the packaging, automotive, and electronics industries seeking reliable and versatile engineering plastics.

Application

• Packaging Materials: Primary resin for producing high-strength, clear bottles (PET bottles) for beverages, food, and personal care products.
• Thermoforming Sheets: Used in the manufacture of trays, blisters, and clamshell packaging for food and consumer goods.
• Textile Fibers: Basis for polyester fibers (PET) used in apparel, home furnishings, and industrial fabrics.
• Engineering Plastics: Component in reinforced compounds for automotive parts, electrical connectors, and housings.
• Film and Sheeting: Production of biaxially oriented films (BOPET) for flexible packaging, magnetic tapes, and electrical insulation.
• Strapping and Monofilaments: Manufacture of high-tenacity strapping for palletizing and monofilaments for industrial brushes and screens.

Quality Control

Our Polyethylenephthalate is manufactured under a stringent quality management system. Production batches are controlled against key parameters including intrinsic viscosity (IV), color, and thermal properties to ensure consistency and performance. Certificates of Analysis (COA) detailing specifications for food contact, bottle grade, or fiber grade are available upon request to meet your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents and excessive heat sources to prevent degradation of polymer properties.
