PolyOne Expands its Reach with Advanced Composite Materials at JEC World 2019

CLEVELAND – September 13, 2018 – Before PolyOne introduced Versaflex™ XP shock absorbing TPEs to the market, it reached out to an independent te

The company’s product engineers developed specifications that included thermal conductivity in plane from 4 to 21 W/m.K (in compliance with ASTM E1461); glow wire resistance of 850°C/0.8mm (IEC 606095-2-12); and enough dimensional stability to allow it to be overmolded directly on LED components. The material added immediate benefits including: complex designs at lower costs than metal; lighter weight; inherent corrosion resistance; adaptability for ingress protection up to IP67; high heat resistance; compliance with UL94 V-0 flammability standards; and options for either electrically conductive or insulating properties.

With about 230 million followers of Islam, Indonesia has the world’s largest Muslim population, and we recognize the importance of Halal compliance in our production of colorants and additives for packaging in this country. Beyond food and beverages, drugs, cosmetics, and any other consumer goods used or applied by humans, the regulation extends to manufacturing processes and the compliance of packaging products.
