Tea board

I am choosing between two materials Durat and Corian. Durat is a material used in hospitals and laborites for its durable and resistant properties and is made from recycled plastics. Corian has the same applications and properties as the Durat but is not as friendly to the earth. Is Corian a material I want to use? It doesn't tie in with the believes of drinking real loose tea which is sustainability.

I will look in to both and see which material is nicer.
