Aardalloy 3326 TPA Aardvark Polymers Acetal (POM) Copolymer

Product Description

Aardalloy 3326 is an acetal alloy formulated for enhanced impact resistance and elongation.
Aardalloy 3326 maintains the high degree of chemical reistance and low fuel permeation rates of unfilled acetals.
Aardalloy 3326 is available in natural white and may be dry colored to suit.
