Product Description
Lustran SMA 2171 is a high heat injection molding grade of impact-modified SMA (styrene/maleic anhydride) terpolymer offering an exceptional balance of processability and performance. Lustran SMA 2171 has high heat resistance coupled with excellent chemical and impact resistance. As with any product, use of Lustran SMA 2171 resin in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
