Polymer selection for durables applications

Selecting the best grade for food contact and non-food contact applications

Brand owners and design engineers continue to find new ways to use Eastman Tritan copolyesters in a wide range of food contact and non-food contact applications. 

Its unique combination of clarity, durability, hydrolytic stability, and heat and chemical resistance makes Tritan ideal for many applications, including:
Food contact applications
•  Commercial housewares
•  Sports bottles
•  Small appliances
•  Infant care
•  Water filtration

Non-food contact applications
•  Appliances
•  Leisure and safety
•  Ophthalmics
•  Oral care
•  Tools
•  In-mold decorations

Starting with your specific needs, Eastman can provide technical expertise and support to help determine the best grade of Tritan for your application.
 
Table 1 compares the properties of the three most popular grades of Tritan for durable goods. All three grades exhibit excellent clarity, durability, hydrolytic stability, and good heat and chemical resistance. In addition, Tritan TX1001 and Tritan TX2001 have a mold release derived from vegetable-based sources. TX2001 is excellent for thick parts. Tritan TX1501HF provides viscosity reductions of 40%–50% relative to TX1001 and is well suited for long flow length, in-mold decoration, and in-mold labeling.
