FDA Approved Thermoplastic Vessels Are Cost-Effective Alternative To Stainless Steel For Pharmaceutical Applications

Owosso, MI. January 30, 2002. Tri-Mer Corporation, a manufacturer of dust and submicron particulate collection systems for food and pharmaceutical environments, has introduced 100% polypropylene process vessels as a non-corroding, cost-saving alternative to stainless steel for a broad range of applications.

Polypropylene is a chemically inert polymer that has outstanding stability, low coefficient of expansion and contraction, excellent dimensional stability, and exceptional acid/alkali resistance. It is a superior moisture barrier, and can be used continuously at up to 220 degrees F. The material is also exceptionally strong and resilient, not subject to fatigue or stress cracking, and easily repaired if damaged.

Tri-Mer thermoplastic vessels do not contain plasticizers, which can leach out or cause embrittlement. They have excellent UV resistance for outstanding weatherability in exposed applications.

The Tri-Mer vessels are up to 1" solid wall polypropylene, with 1-1/2" foundation plates for optimum rigidity. They are appropriate for use as process vessels, batch blend tanks, bioreactors, fermenters, and vial stopper washers, and are manufactured in sizes to 100'.
