Polystyrene - Impact
Description
The high impact polystyrene for injection molding. This easy processing grade allows fast cycle times
with minimal post stress resulting in outstanding impact retention. Advanced rubber particle size control makes this polymer
the choice for all high gloss applications.
General Information:
- This material complies with FDA requirements as described in 21 CFR §177.1640.
- This material holds Underwriters Laboratory recognition 94HB; see UL File E55470 at www.UL.com.
- USP Class VI
- Material Safety Data Sheets are available to help customers satisfy their safety needs.
