Don’t Drag Your 2016 Problems Into the New Year

17wmt-jumbo-v2ARM would like to help you solve your lingering 2016 process issues and problems before they become your headache of 2017.

Join your ARM colleagues for the last troubleshooting call of of the year on Tuesday, December 20, at 2 PM Central.

Push your troubles onto the shoulders of our moderators, Ron Cooke (ExxonMobil Chemical Company) and Sandy Scaccia (Norstar). Then enjoy the holiday with a clear conscience and a clean slate.

These calls are an opportunity for molders to inquire about any challenges in their process and share solutions with one another. To get signed up for the call, email ARM staff.

President’s Message: Celebrating our Roto Family

Now that the Fall Meeting is over, it is time to reflect on the reason to celebrate this specific Anniversary.

My personal belief is that we have enough things to worry about in our everyday lives that we should use any excuse to have fun and celebrate life. Anniversaries are always a good reason to have a party.

We normally do that for the 10th, 25th, 50th, etc.  This was the 40th anniversary of our industry and we decided not to wait until the 50th to have a party, and more than a party, to bring all possible luminaries to share their experiences with those of us that not were involved with the association at the beginning.  I know a lot of you were not even born!

Honestly, I think we really have a lot to celebrate and be proud of.  Our Association has done a great job for the industry and all of us have contributed somehow to this success.

From those 21 company owners that met 40 years ago in cold Chicago and decided take money from their pockets and create a group to further develop a new way to produce plastic products, to where we are today as a worldwide industry, a lot of things have happened.  And many of them have happened precisely because of that union between competitors that saw far beyond their personal needs or difficulties.

Industrial associations exist all over the world.  Not many function as ours.  We have learned how to use the technical knowledge without letting it become ruined by commercial topics.  Most of all, we have learned that competitors are great people with very similar problems as ours, and normally kind enough to share experiences and solutions.

We learned that our association became our Roto Family, and that we can count on each other always, and that, dear friends, is a huge reason to celebrate.

Annual Meeting Takeaways: Polypropylene Has a Place in Rotomolding

Over the next few weeks, the ARM blog will highlight the takeaway points from some of the key presentations given at ARM’s 40th Annual Meeting in New Orleans. The first of these posts comes from Tom Wyszynski, a new inductee in the Rotational Molding Hall of Fame, who summarizes the key points of his presentation on Septmember 27.

Polypropylene is an incredible polymer. Contrary to what some may think, there is a place for it in rotational molding. Designers, engineers, and molders need to remember it is not polyethylene – and it is not trying to be polyethylene.

The characteristics of polypropylene are very different from those of polyethylene – and that’s a good thing. PP has the ability to do well in higher temperature conditions than does PE. Polypropylene has very good chemical resistance and a very high flexural modulus. Many types of tanks, bins, and assorted containers are molded from polypropylene.

The high melt point and deflection temperature allow polypropylene to handle applications polyethylene could never touch. Those same thermal traits allow polypropylene to be disinfected using and autoclave. The 120°C operating temperature of an autoclave is almost at the melt point of some LLDPEs. Food and pharmaceutical applications love the fact this polymer can be sterilized via autoclave.

The copolymer polypropylenes being produced today for rotomolding are light years ahead of the compounds available years back. Careful selection and incorporation of impact modifiers as well as thermal and ultraviolet light stabilizers have really improved polypropylenes. While polypropylene may not have the impact resistance of PE many applications simply are not impact sensitive.

We deal with many things in our lives that are not impact resistant yet they serve a function. Polypropylene has a place in rotational molding but it needs to be the correct application.
