1. High-Temperature Solid Silicone Sheeting

    July 2022 was the third-hottest July on record in the U.S., according to the National Oceanic and Atmospheric Administration (NOAA). Here in Southern California where ElastaPro is located, inland regions have seen temperatures exceed 100°F this August.

    Maybe it doesn’t get that hot in your backyard, but there are plenty of places indoors that do – and handling the heat isn’t just a summertime challenge. For example, the gaskets and seals on engines, pumps, compressors, and appliances all need high-temperature resistance.

    Standard silicone elastomers are a great choice for temperatures up to 500°F, but what if you need solid sheeting for extreme heat? From automobiles to aerospace and aviation, there are plenty of applications for higher-temperature materials.

    Extreme high-temperature grade silicone sheeting from ElastaPro uses high-quality heat stabilizers, including our own ESSHTA technology, which is rated up to 600°F/300°C. These Made in USA materials are great for die cutting and are available in:

    • 55 or 60 durometer
    • thicknesses from 0.10″ to .500″
    • widths up to 60″
    • various color and catalyst options

    Enjoy the rest of your summer – and stay cool in the heat.

  2. Our Most Valuable Material Isn’t a Precious Metal

    Gold, silver, platinum, and palladium. From jewelry to electronics, these precious metals are rare and have great economic value. Silicon metal isn’t precious, and its ingredients are commonly found in Earth’s crust. Yet, silicon metal is incredibly valuable because it’s a major ingredient in silicone rubber, solar panels, electric vehicles, semiconductor chips, aluminum, defense technologies – and much more.

    Today, China refines 70% of the world’s silicon metal. The United States refines only 5%. Although the U.S. government is recognizing the importance of increasing our refining capacity, it takes years to build silicon metal refineries – and the refining process requires a great deal of energy. Meanwhile, demand for silicon metal is expected to grow 50% over the next 5 to 10 years.  

    Do we want to depend on China for our supply of silicon metal? For that matter, do we want to depend on overseas suppliers for PDMS, an important member of the silicone family? Most PDMS production has left North America for Asia, but demand for silicone keeps growing. That’s why members of the silicone industry, myself included, are asking the U.S. government to take bold action.

    What can you do as a silicone buyer? Whenever possible, please choose products and materials that are Made in USA. Your buying decisions will help spur investments in domestic capacity, and you’ll get quality silicones with ingredients you can trust.

  3. Silicone Supply

    Everybody’s talking about silicone supply, but elastomers that don’t meet specifications aren’t the right way to meet demand. Don’t let them put your projects at risk.

    ElastaPro tests the physical properties for each and every lot of all of our sheet materials. Our in-house testing laboratory can provide you with test results for specifications such as:

    • durometer
    • tensile strength
    • tear strength
    • percent elongation
    • fluid & heat aging and much more.

    Recently, our in-house lab added a third Tensometer and a more sophisticated Shore A Durometer instrument for the most accurate results. ElastaPro also sends samples to third-party accredited laboratories to confirm the results of our own testing.

    The benefits don’t end there. All of our silicones are Made in the USA. We also have a large selection of stocked items and can take you from lab batch to large-scale production.

  4. Silicone Supply Chain Insights

    Have you ever heard the expression “can’t see the forest for the trees”? It happens when the details of a problem are so intense that it’s hard to look at the situation as a whole. By changing your focus, however, you can see things in a new way.


    The silicone shortage is no exception. Buyers are worried about supplies and engineers are excited about new applications. So when I participated in a Silicone 2021 Livestream for Rubber and Plastics News (RPN), both topics (and others) were on the agenda.

  10. Silicone Demand is Rising. Now What?

    Silicone demand is rising at a time when major suppliers are warning customers about longer lead times and tightening supply constraints. The causes include an end to COVID-related slowdowns, a shortage of steel, and a rising tide of shipping delays. Whether these delays occur on land because of bad weather or at sea because there aren’t enough personnel in port to receive cargo, silicone buyers are concerned.

    During my two decades in the silicone rubber business, I’ve seen many supply chain issues. What we are experiencing in 2021 will pass as well. The factors that are driving today’s supply constraints are different than in 2018, a shortage you may recall. Back then, there wasn’t enough capacity to meet global demand for polydimethylsiloxane (PDMS), the basic building block of silicone rubber.

    The good news in 2021 (and we’d all like some good news, wouldn’t we?) is that we expect silicone supply to stabilize this year. In fact, we can anticipate some supply chain normalcy beginning in Q3. In the meantime, however, silicone buyers can anticipate longer lead times and potential price increases as major suppliers look to meet a post-COVID rebound in demand.

    Here’s some more good news, especially if you remain concerned about silicone demand. Current silicoine demand levels are not, in my opinion, significantly higher than they were before COVID-19 (other than demand for healthcare elastomers). Therefore, the major suppliers are simply playing catch-up rather than trying to add significant capacity. These suppliers do a great job at managing flow, but the current situation is like a long and heavy train. Once stopped, it takes a while for everything to start moving again.

    What does this mean for you? Please know that ElastaPro continues to work very closely with our supplier partners to secure raw materials for solid silicone sheeting and silicone compounds. At the same time, we’re doing all we can to control costs. Silicone may be in short supply today, but that won’t last forever. What’s built-to-last, however, are supplier relationships based on trust.
