Critical Cleaning Hands-on Workshop Do it; learn it! The one-day workshop teaches how cleaning and cleanliness testing work. By participating in hands-on exercises of techniques for cleaning and cleanliness verification, attendees gain the understanding and knowledge to make practical, effective, and sustainable manufacturing decisions. While exercises are supplemented by demonstrations and tutorials, the workshop is not death by PowerPoint! Topics include aqueous, solvent, and “non-chemical” cleaning, including cleaning chemicals and cleaning processes (spray, ultrasonics, cyclic nucleation, in-line, batch). Most manufactured product and product contact surfaces require cleaning during (and sometimes after) manufacture and assembly.  Examples of areas where effective cleaning is essential include: metal fabrication, product assembly, optics, electronics, microelectronics, wafer fab, medical devices, aerospace/aeronautics, military, and additive manufacturing. WHAT DO YOU CALL CLEANING? There are many different terms for cleaning. Cleaning Precision Cleaning Critical Cleaning Safety/Critical Cleaning Surface Prep for Finishing Technical Cleanliness Residue Removal WHO WILL BENEFIT FROM THE WORKSHOP If you or your company fabricates, finishes, maintains or repairs product or product contact surfaces (like reaction vessels), this workshop is time well-spent. If you sell chemicals or cleaning equipment, this workshop will help you better understand and optimize the market for your products. Examples include: Manufacturing Engineers Product Designers Managers Sales and Marketing Managers Facilities Personnel Assemblers, operators Process Technicians Quality Control Personnel Regulatory Affairs Experts (industry, military, and government) Safety/environmental professionals​ ​ Participants will receive a PDF Certificate of Completion with continuing education credits from Sam Houston State University.

Sulzer Chemtech and Borealis have launched new PP foam extrusion technology said to lower cost and increase efficiency.  

An innovative process for the cost-effective extrusion of expanded polypropylene (ePP) beads was recently developed jointly by Switzerland-based Sulzer Chemtech and Austria’s Borealis. This new PP foam extrusion technology reportedly enables lower cost and increased efficiency across the value chain, supports the end-market efforts towards more circular solutions, and is expected to cut manufacturing costs by up to 60%.

To support the large-scale adoption of ePP, Sulzer Chemtech is now launching a new and innovative compounding production line.. As opposed to conventional autoclave production methods, Sulzer Chemtech’s innovative system relies on extrusion with direct gas impregnation, offering an easy to implement alternative with a quick return on investment.

Foam molders, such as packaging manufacturers, can implement the compounding line to considerably reduce the costs associated with material supply, warehousing and intermediate transportation. As such, companies can offer ePP parts at more competitive prices while supporting the adoption of easy-to-recycle polyolefin applications. Additional benefits include having full control over the properties of the ePP, such as bulk density, closed cell content and bead size distribution, as well as maximum flexibility in fine-tuning the recipes. Also, the highly automated process keeps maintenance requirements low and simplifies operations. In addition, the extruded beads subsequently can be easily processed with standard steam pressure in steam chest molding machines to obtain molded bead foam products with specific shapes.

In addition, Sulzer Chemtech and Borealis are developing an alternative that can use carbon dioxide, supporting different customer needs and plant settings. “Collaborating with an industry leader like Sulzer has been a pleasure. This innovation will further drive the adoption of our PP foam solutions, supporting the transition to a circular economy of plastics. This is how we re-invent for more sustainable living,” said Christopher McArdle, Borealis’ v.p. polyolefins strategy & new business development.

Said Sulzer’s division president Torsten Wintergerste, “We are extremely pleased with the advanced ePP production line that we have developed together with Borealis. The result of this collaboration truly attests to the extensive expertise of both companies. Using our latest solution, customers will be able to benefit from cutting-edge equipment with enhanced performance as well as high-quality PP for the production of best-in.class foams.”

You would think we’d know all there is to know about a material that was commercialized 80 years ago. Not so for polyethylene. Let’s start by brushing up on the basics.

Don’t assume you know everything there is to know about PE because it’s been around so long. Here is yet another example of how the performance of PE is influenced by molecular weight and density.
