In addition to use in their basic form, TPEs are widely used to modify the properties of rigid thermoplastics, usually improving impact strength. High Percentage waste Going quickly from a state of high stress to one of low stress can increase the amount of shrinkage.

ECCOH™ Low Smoke and Fume Non-Halogen Formulation 5983 With high environmental stress cracking resistance for power cable jacketing The new ECCOH™ 5983 formulation helps prevent environmental stress cracking in low and medium-voltage armored power cables, helping to prevent costly cable damage and disrupted power supply. The ECCOH 5983 formulation has been developed to help prevent stress cracking in armored cables by offering high tear strength and elongation at break at temperatures ranging from -25°C to 90°C. MARKETS AND APPLICATIONS • Cable jackets for low and medium-voltage power cables with metal armoring, typically installed underground or where installation requires them to be bent • Armored cable applications that require compliance with LTS1 requirements as per the BS 7655-6.1 standard IMPACT • High environmental stress cracking resistance • High tear strength and elongation at break at temperatures ranging from -25°C to 90°C • Flame retardant performance • Limiting oxygen index (LOI) of 36% • Exceeds BS 7655-6.1:1997 standard criteria for LTS1–LTS4 for complex designs and armored cables PRODUCT BULLETIN Cable jacket liable to cracking Power Cable Cross Section Metal armoring 1.844.4AVIENT www.avient.com Copyright © 2023, Avient Corporation.

THE SOLUTION Gravi-Tech™ density-modified formulations are unique, high-density materials developed as thermoplastic-based alternatives to lead and other traditional metals. THE IMPACT Gravi-Tech high-density formulations enabled API to design and mold a patented, full-opening flapper valve that is not only unique in the market, but also offers important cost, performance and environmental advantages over brass.. • System cost reduction = competitive advantage: The PolyChek valve featuring Gravi-Tech materials offer customers faster installation, less maintenance and longer life. • Design freedom = unique product offering: The ability to injection mold Gravi-Tech materials instead of machining brass enabled API to design a cost-effective, full-opening flapper valve that is 100% pigable. • High performance = customer satisfaction: The PolyChek valve gives API’s customers the ability to create all-plastic piping systems that eliminate leakage and weak spots. • Elimination of lead = increased safety and compliance: Replacing brass with Gravi-Tech high-density formulations eliminates health and safety concerns about lead. • Use of existing tooling = lower capital costs: API was able to use the same mold originally designed for nylon to run the Gravi-Tech materials, saving the substantial costs of retooling.

It is widely used to manufacture films, bags, trays, bottles, and containers, and it has excellent overall properties such as impact and tensile strength, clarity, processability, colorability, and durability. For these reasons plastics for packaging play an important role in everyday life, however, due to the high volume and rather short usage life of plastic packaging items, they require appropriate management, especially at the end of their life. ISSUES WITH POST-CONSUMER RECYCLATES (PCR) Very often post-consumer recyclates (PCRs) are not of a good enough quality to withstand efficient processing, nor can they offer long-term stability for high-value or high-performance end applications.
