Product Text
Celanex 2401MT ECO-B 352 is a special grade developed for medical industry applications and complies with:
CFR 21 (177.1660) of the Food and Drug Administration (FDA), and
the corresponding EU and national registry regulatory requirements;
biocompatibility corresponding to USP 23 Class VI/*** 10993;
is listed in the Drug Master File (DMF 10047 (US)/10033 (EU)) and the Device Master File (MAF 443 (US)/1078 (EU)),
and contains no animal products.
Celanex庐 2401MT ECO-B 352 incorporates 39% of biobased content derived from waste by weight in the finished product through mass balance allocation. The product is a drop-in replacement to the standard grade with the same performance and processing properties and contributes to the displacement of virgin fossil fuel resources. The biobased source and allocated content in the product are certified according to ISCC PLUS mass balance approach.

Additional information
Injection molding
To minimize the volatile content in the final product, dry the resin to 鈮�0.01% water content. In injection molding, use the lowest possible melt temperature (recommended 240 掳C) and shortest feasible residence time (recommended 2-3 minutes). Store the parts in a ventilated, clean area before use. If assistance is needed please contact your Celanese account representative.
These recommendations are based on internal Celanese testing. For drying and injection molding conditions outside the above parameters, customer must test for and verify suitably low volatiles emissions on molded articles to confirm the final product is suitably pure for its intended use.
Processing Notes
Pre-Drying
To avoid hydrolytic degradation during processing, CELANEX resins have to be dried to a moisture level equal to or less than 0.01%. Drying should be done in a dehumidifying hopper dryer capable of dewpoints <-40掳C (-40掳F) at 140掳C (284掳F) for 4-6 hours.
Storage
For subsequent storage of the material in the dryer until processed (<= 60 h) it is necessary to lower the temperature to 100掳 C.
