Delivering on critical application demands, it provides weldability, kink resistance, and tensile strength performance comparable to leading medical tubing materials, including silicone and TPE. Offering reliable performance, optical clarity and expanded design freedom, these medical- grade TPEs may be customized to meet specific regulatory demands or application needs.

Examples of common applications include medical tubing, inflatables, packaging film and sheets, garden hoses, toys and automotive plastics. 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.
