It has no negative effect on recyclability, physical performance characteristics or color of the recycled material. In some situations the Ultimate UV range can vastly improve both the processing and mechanical properties of packaging incorporating recycled material. Processing conditions can cause material properties to shift from the values stated in the information.

Couple this with the residual heat in the material and a situation is created that mimics a transfer press. Processing conditions can cause material properties to shift from the values stated in the information. Processing conditions can cause material properties to shift from the values stated in the information.

Glass fiber reinforced polymer (GFRP) dowel bars offer advantages over traditional steel or epoxy- coated steel bars: • Electromagnetic transparency: ideal for high- speed toll roads to prevent interference • Corrosion resistance: the GFRP material will not rust or corrode in salt or alkaline environments • Light weight: less than one-third the weight of steel • Does not bond to concrete: eliminates the need for sleeves or grease to allow for expansion and contraction Glasforms™ composite dowel bars are tested and approved to meet the following requirements: • ASTM 1356 Glass Transition Temperature • ASTM D570 Water Absorption • ASTM 2344 Short Beam Strength • ASTM 7617 Transverse Shear Strength Glasforms™ Composite Dowel Bars for Concrete Pavement Construction APPLICATION OVERVIEW WHY GLASFORMS PULTRUDED COMPOSITES?

Further, as a result of Avient's strategic shift to an innovator of materials solutions, it has completed several acquisitions and divestitures which have resulted in a significant amount of intangible asset amortization.

Scenarios for 2030 predict that of the 1300kt of PET material coming from PET bottles collected from the market yearly, between 20 to 30% will be colored bottles;2 these will enter their respective sorting and collection systems to ultimately produce rPET material that will be fed as new raw material for non-food PET applications. Processing conditions can cause material properties to shift from the values stated in the information. Bottle A is the original bottle with 100% virgin material and a combination of Amosorb SolO2-2 at 4% with Fortis Amber-1 at 0.09% LDR.
