Description

Fuji-Ionomer CAS NO 70644-84-7 is a specialized ionomer resin known for its unique combination of toughness, clarity, and adhesion properties. This material is engineered to provide exceptional performance in applications requiring strong bonding and chemical resistance. It is particularly valuable for manufacturers in the packaging, automotive, and specialty coatings industries seeking reliable, high-performance polymer solutions.

Application

• Packaging Films: Used as a sealant layer in multi-layer food and medical packaging due to its excellent seal integrity and adhesion to various substrates.
• Automotive Parts: Employed in interior trim components and under-the-hood applications where chemical resistance and durability are critical.
• Specialty Coatings: Serves as a base resin for coatings on metals, glass, and plastics, offering enhanced adhesion and barrier properties.
• Adhesives & Sealants: Formulated into hot-melt and reactive adhesives for bonding dissimilar materials in construction and assembly.
• Golf Ball Covers: A key material in the manufacture of durable, high-performance golf ball covers that provide excellent cut resistance and feel.
• Medical Device Components: Utilized in non-implantable medical device housings and parts requiring clarity and compliance with material safety standards.

Quality Control

Our Fuji-Ionomer is produced under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. While specific grades may vary, quality is assured through comprehensive testing including melt flow index, acid content, and neutralization level analysis. Certificates of Analysis (COA) documenting key physical and chemical parameters 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed when not in use to prevent moisture absorption, which can affect processing and final product properties. Keep away from strong heat sources and incompatible materials.
