In this first wave of ENGAGE experiences, we reached over 2,300 associates at 50 locations. Our latest grades offer up to 50% lower haze and reduced impact on the PET recycle stream compared to previous grades. This organization is CEO led, cross- sector, not-for-profit made up of approximately 50 companies.

Carbon fiber increases modulus more than glass or natural fibers and a composite with 50% fiber will be stiffer than one containing 30%. Long fiber composites typically have similar impact performance at -60°F (-50°C) as they do at room temperature.
