Selected for their strong performance and durability, phthalates are the most commonly used plasticizers in the world.1 In recent years, concerns have been raised over the use of phthalates, giving rise to myths and unfounded speculation. PHTHALATES FACTS PHTHALATES ARE KNOWN TO BREAK DOWN IN THE HUMAN BODY Research has shown that after entering the body, phthalate are broken down into metabolites within minutes and pass out quickly in urine.2 PHTHALATE EXPOSURE IS CONSIDERED LOW Despite the fact that phthalates are used in a wide range of products, human exposure from all sources is considered to be extremely low.2 PHTHALATES ARE A USEFUL CHOICE FOR HEALTHCARE Flexible vinyl tubing does not react with most medications, allowing for reliable administration of drugs, while flexible vinyl bags prevent blood contamination and extend shelf life of the blood.3 PHTHALATES ARE REGULATED Based on earlier studies, a few specific phthalates have been banned for use in toys or other items for sale to children under twelve to reduce risk of overexposure through hand-to- mouth behaviors. 1 Source: chemicalsafetyfacts.org 2 Source: Centers for Disease Control and Prevention 3 Source: thisisplastics.com www.avient.com Copyright © 2020, Avient Corporation.

They have outstanding UV and weather resistance, passing Arrhenius lifetime prediction tests of 20,000 hours as per the IEC 60216-1 standard. They pass EN 50618 and IEC 60332-1 standards on the assembled cable (if the cable jacketing and insulation are both produced with ECCOH XL 8148 solutions).

Guided by their initiative to develop capabilities that provide additional protection for soldiers while reducing time and logistic requirements,1 the U.S. With our hardware fabrication capabilities and Avient’s knowledge of composite ballistic protection technology, we were able to create modular systems that reduce time and logistic requirements for our brave soldiers.” 1 https://www.erdc.usace.army.mil/Missions/Military-Engineering/Deployable-Force-Protection-Demo/ To learn more about ballistic resistant solutions from Avient, visit avient.com or click to request a quote.

The resulting tensile test data shown in Figure 1 gives an indication of the variation in material response that can be observed as a function of the fibre orientations. In reality, the material response can fall anywhere between the curves shown in Figure 1. Figure 1: Tensile test data as a function of the fibre orientation 0° (orange), 45° (green), 90° (blue) https://www.hexagonmi.com Figure 4: Failure location in the flexural test for the isotropic modelling Figure 6: Failure location in the tensile test for the isotropic modelling approach (left), Digimat anisotropic modelling approach (middle) and reality (right) Figure 3: Flexural test results with the isotropic modelling approach (orange) and Digimat anisotropic modelling approach (green) Figure 5: Tensile test results with the isotropic modelling approach (orange) and Digimat anisotropic modelling approach (green) Figure 5 shows the tensile test results with, again, a convincing advantage for the Digimat anisotropic modelling approach against the isotropic modelling approach.

HMPE for example, has a specific gravity less than 1 and will float in water. • Corrosion Since our products are non-corrosive, they offer outstanding performance in corrosive environments, including marine and off- shore applications. • Conductivity High-performance synthetic fibers act as a barrier between eletrical components. • Creep When exposed to static long-term loads, synthetic fibers stretch very little.
