President’s Message

Dear SPE-STX Members, 


I hope all our members and their families are staying safe and doing well during this unprecedented national crisis. I know many of our work lives or businesses are severely impacted by this rapid upheaval in the economy. Although many support business are severely impacted, our region’s economic situation remains strong which plays a vital role in providing feedstocks and goods that our medical front-line workers are using along with providing protective packaging that preserves our food supply.

These are truly great examples of the need for having plastic materials available and made in the USA. The shortages of protective-gear within the USA brings to light the long supply-chain from overseas due to the exporting of many of our converter manufacturing jobs. I suspect the USA and the region will undergo an economic boom with the development of manufacturing facilities that will make the USA self-reliant for medical equipment and supplies.

As I suspect many of our members are helping our community in various ways, and I do have a story to share with you.

A member of my extended family is a nurse in the medical field and of course has concerns of being exposed or exposing others to covid-19. A number of these nurses and their friends wanted to sew surgical masks for medical workers and patients that work or visit clinics which perform various infusion treatments to patients. Many of these patients are elderly and are in the high-risk category for covid-19. Since nearly all the N95 masks, so often mentioned in the news are being reserved for front-line workers (medical, emergency personnel, etc..), none are available for these secondary needs at clinics for both workers and patients.

I was contacted by the person working with the nurses to design a sewn mask that has similar performance to that of the N95 masks which can stop germs and most viruses. The goal was to design a mask that could be reused from widely available materials and be completely hand assembled using sewing processes. One suggestion was to use a typical house-hold HVAC air handler filter as part of the design.

I took to the task using all of that Sunday delving into the performance details of the N95 masks and comparing that to HVAC air-filters. Not surprisingly a performance grade HEPA filter (MERV-13) has similar filtering properties to that of the N95 mask. I provided calculations for pressure drop across the house-hold air filter given the size constraints of the typical sewn mask and verified the design. I also mentioned that the sewn portion of the mask can be washed, but the performance properties of the air filter are altered if getting wet let alone in contact with detergent. Therefore, I suggested the design have a sewn mask with a pocket that allows for removal of the air filter. The use of the sewn mask would require washing of the cloth and replacing of the air filter segment. If needing to reuse the air filter segment, that sterilization would be needed and to use a UV light for several hours.

Upon the verification of the design performance, the ability to replace the filter segment, and the ability re-sterilize the air-filter segment using UV light, the folks sewing the masks took to task and have been busily working ever since.

This is a very positive story about our entire community pulling together with each using their unique talents. It is also a cautionary tale that in a short amount of time “air handler filters” maybe in short supply. You may want to purchase a few extra air filters and place them next to your toilet paper cache.

Stay Safe!

Peter Lauzon, President SPE-STX


How SPE Members Can Support Graduates Entering The Workforce

The Connections You Have That You Don’t Know You Have

When students or university counselors approach members of SPE-South Texas Section about employment opportunities, we need to reach out to those business connections we have made throughout our careers. 

It is important to understand that today's environment makes it difficult for graduating students to find full time employment. However, just look back at your own career and you will be surprised just how many contacts you have made.

So how do we participate with the HR recruiters? 

Every member (whether your work is technical, sales, or management) should reach out to the HR department. Inform HR that there are excellent prospects for recruitment within those students we have worked hard to support. If HR shows interest, then you can give those students and counselors a great avenue to pursue employment. Every company can gain from the young minds of these graduates.

The Importance of Chemical Stabilization in Recycled Material for Corrugated and Conduit Polyolefin Pipes

Ian P. Query and Robert L Sherman Jr., Baerlocher USA, Cincinnati, OH


Much attention has been given to stabilization packages for polyolefin pressure pipes over the past couple decades, however corrugated and conduit pipes have generally been ignored with respect to more robust stabilization packages. Certain groups such as the Florida Department of Transportation have set rules establishing oxidative resistance in HDPE corrugated pipes, but few others have followed this example. A discussion of the simplicity and importance of pipe resin stabilization as well as examples from stabilized pipes will be covered.

Polyolefins 2021 Discussion

POC 2021 Topics

Tom Walsh reported at the March Board meeting on the analysis conducted on the 2020 Polyolefins Conference. That report is Attachment 1 to these minutes.

Peter Lauzon reported at the March Board meeting on the results of the survey of exhibitors. The current results of the survey of attendees is shown in Attachment 2. Peter suggested that the survey for the exhibitors could be included as a link in their Welcome Package listing local restaurants. A raffle could be developed to incentivize exhibitor respondents. We could also develop a similar welcome package for attendees also including a link to the attendee survey. A raffle could be developed to incentivize attendee respondents.

Tom Walsh reported on a demographic analysis of the membership of the South Texas Section. That report is Attachment 3 to these minutes. Based on the Analysis of the POC in conjunction with the Analysis of South Texas membership the following points were discussed:

In the continuing discussion of potential directions for the 2021 Polyolefins Conference, Board meeting members made the following comments:

The question was asked what value added do these partners bring to the conference? The Polyolefins Committee should address this question with these partners. Are these divisions able to provide more support in attracting more converters, more exhibitors, and especially new sponsors? This needs to be addressed. In addition, the South Texas Section needs to become more involved in the Program organization. We need to recruit session organizers for the conference as well as organizing committee volunteers. Preston McDaniel stated that he thought that having a job to do, such as organizing and moderating a session at the conference would be attractive to several of his colleagues. He agreed to approach them with this concept.

Peter Lauzon added that we need to attract more converters both as attendees and as presenters.

This brought up the question of what topics to address in the upcoming 2021 conference. We need volunteers to focus on topics that are attractive to both the resin manufacturers and to converters.

Suggested topics included the following:

Fee structures for the conference were also discussed briefly. It was discussed that Kevin Alexander has probably raised Exhibitor fees enough. We did not sell out the exhibits this time. Tom Walsh has provided a listing of competitive commercial conferences and our fee structure is very low (Attachment 4). We could easily increase the differential for SPE Members and non-SPE members. There were a total of 52 registrations that paid the non-SPE member rate. Why?

Again, it was discussed, that the current COVID-19 crisis pointed out how lucky our timing for the 2020 conference was. If this crisis had developed earlier, we would have had to cancel the conference. This would have had a catastrophic economic impact on the South Texas Section. We need keep this in mind going forward.

It was pointed out that epidemiology experts are worried that next winter will see a re-occurrence of COVID-19 and a vaccine may not yet be available. We need to monitor this situation and plan for potential disruptions of the conference. If COVID-19 becomes active next winter and social distancing is put back into effect, what would this do to exhibitor interest in the conference? Social distancing was non-existent in POC 2020.
