About Ethylene Vinyl Acetate ISI Certification
Ethylene vinyl acetate (EVA) copolymers arecovered under IS 13601:1993. This standard specifies the requirements andsampling and testing techniques for ethylene-vinyl acetate (EVA) copolymer tomanufacture plastic objects used in contact with foodstuffs, pharmaceuticals,and drinking water. Other than toxicological considerations, this standard doesnot attempt to prove the appropriateness of the packing media with specificcommodities, medications, and drinking water. AN global service proudly offers the comprehensive package forConsultancy Services to obtain a mandatory BIS License to use ISI mark onEthylene Vinyl Acetate Copolymers (EVA).
Consistent Quality with ISI CertificationEach batch of EVA granules is ISI certified, ensuring that the material meets stringent industry standards for safety and performance. The certification confirms the granules' high purity and reliable characteristics, essential for industrial manufacturing and export processes.
Ideal for Diverse Industrial ApplicationsEVA granules serve multiple industries, including footwear production, adhesive manufacturing, and packaging solutions. Their adjustable melt flow index and vinyl acetate content allow customization to suit precise manufacturing requirements, improving both efficiency and product quality.
Handling, Storage, and LongevityProper storage of EVA granules is crucial. Keep them in a cool, dry environment away from sunlight to maintain quality, with a typical shelf life of 12-24 months. Adhering to suggested conditions preserves mechanical properties and ensures optimal material performance.
FAQ's of Ethylene Vinyl Acetate ISI Certification:
Q: How is Ethylene Vinyl Acetate ISI Certification obtained for industrial use?
A: ISI Certification is achieved by meeting the standards set by the Bureau of Indian Standards (BIS), which involves rigorous testing of melt flow index, vinyl acetate content, mechanical strength, and purity. Manufacturers and suppliers must submit product samples and relevant documentation for evaluation.
Q: What industrial applications are best suited for EVA granules with ISI Certification?
A: EVA granules are widely used in industries such as footwear, adhesives, packaging, and other manufacturing processes due to their durability, flexibility, and high purity. The certification assures consistent quality for demanding production environments.
Q: When is it necessary to check the melt flow index (MFI) of EVA granules?
A: Checking the melt flow index is essential before processing, as different grades (ranging from 2-25 g/10 min) influence the extrusion, molding, and product properties. Manufacturers must verify MFI to match specific application and machinery requirements.
Q: Where should EVA granules be stored to ensure maximum shelf life and quality?
A: EVA granules should be stored in a cool, dry place, away from direct sunlight. Proper storage helps retain their mechanical and chemical properties, extending the shelf life to between 12 and 24 months.
Q: What is the benefit of choosing ISI certified EVA granules over non-certified alternatives?
A: ISI certified EVA granules guarantee compliance with recognized safety and quality standards, reducing the risk of faults in finished products. Certification ensures traceability, reliability, and suitability for critical industrial applications.
Q: How are the vinyl acetate content and density varied in EVA granules to suit different uses?
A: The vinyl acetate content (10%-40%) and density (0.93-0.95 g/cm3) are tailored during manufacturing to optimize properties such as flexibility, strength, and melt behavior, adapting EVA granules for specific industrial functions.
