Description

Terylene CAS NO 79028-56-1 is a high-performance synthetic polymer, specifically a type of polyethylene terephthalate (PET) resin, known for its exceptional strength, durability, and chemical resistance. This material is critical for applications demanding dimensional stability, low moisture absorption, and excellent electrical insulation properties. It is essential for manufacturers in the packaging, textile, and engineering plastics industries seeking reliable raw materials for high-quality end products.

Application

• Textile Fibers: Primary raw material for producing high-tenacity polyester fibers used in clothing, home furnishings, and industrial fabrics.
• Packaging Films: Manufacture of biaxially oriented PET (BOPET) films for food packaging, lamination, and metallized applications due to its excellent barrier properties.
• Engineering Plastics: Used in injection molding and extrusion for producing durable components in automotive, electrical, and consumer goods.
• Beverage Bottles: Key resin for the production of clear, lightweight, and shatter-resistant plastic bottles.
• Thermoforming Sheets: Base polymer for sheets used in food trays, blisters, and other formed packaging solutions.
• Industrial Yarns and Ropes: Production of high-strength cords, ropes, and conveyor belts for industrial use.

Quality Control

Our Terylene is manufactured under stringent quality management systems to ensure batch-to-batch consistency and performance. Quality is verified through comprehensive testing including intrinsic viscosity (IV), melting point, color, and contaminant analysis. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance protocols.

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 heat sources and open flames. Ensure the storage area is free from moisture to prevent any potential degradation of polymer properties.
