3 Common Misconceptions About Durometer

Posted by Andrew Bonar

The Shore durometer (pictured right) is a scale for measuring the hardness of a material, such as rubber, plastic, thermal  plastics (TPE), and rigid plastics. The term "durometer" is often used to describe a material's rating on the scale, for example “this material has a durometer of 60.”
  
It's worth noting, there are a variety of durometer scales since elastomeric and plastic resins vary over a wider range than one scale can accommodate. Download our comparison chart to see how these scales overlap.
 
Durometer hardness is one of many physical properties considered when selecting a material for a specific application. Beware of some common misconceptions. Durometer hardness is often inaccurately confused with the properties described below.

Tolerance Challenges When Die Cutting Soft, Flexible, Thick Materials

Posted by Katie Sullivan

Jan 17, 2019 9:20:00 AM

Technological advances in properties of soft, flexible foam and elastomeric materials have continued to advance. These thick, soft, flexible foams and elastomers are ideal materials for sealing, gasketing and cushioning across many industries and applications. They compress, form to irregular surfaces, bend, and flex within an application without damage or de-lamination, but from the perspective of the die cutter, may also introduce challenges when trying to achieve the tight dimensional tolerances common in metal and plastic-molded parts.

Why is it so imperative that plastic injection molding companies provide value added services and secondary manufacturing services to their customers after molding their parts? The answer is easy! Many end-customers of plastic injection molders are looking for vendor consolidation and supply chain simplification. They want to cut out and skip steps in their supply chain, sequentially helping to reduce costs and save time!

Your Solution Experts on Vibration Control

Just about everything that has been engineered is likely to experience vibration. Unfortunately, it has been proven that vibration can be responsible for causing extreme damage to some applications. The source of vibration can come from impact, internal motors or external sources. Vibration happens all around us whether we know it or not. Sometimes it’s evident when you hear buzzing, squeaking, or rattling noises such as when you run your noisy washing machine or dish washer. Other times you may notice the sensation of vibration when you are driving a car over a bumpy road or when you see the cables on a bridge shaking back and forth on a windy day. Most of us experience the harsh impact of an object when we drop our cell phones on the solid ground.

Compression Force Deflection Demonstration of PORON and BISCO Foams

Posted by Crystal Deel

Jul 7, 2016 8:30:00 AM

Marian has a brand new demonstration piece to share with the world! Strategically named "Test My Memory," the demo illustrates the impact of compression cycling over time with 4 different foams. "Test My Memory" demonstrates that certain foams depreciate as it takes on impact over time, whereas other foams such as PORON® Urethaneand BISCO® Silicone resist the compression set, ensuring an excellent seal. Foams that resist a compression set make for a good seal in a gasket because the material rebounds to fill any potential gaps that could allow for water or other outside particles to pass through.

Compression Force Deflection in Foam Gaskets: A Critical Property

Posted by Crystal Deel

Feb 2, 2016 9:56:28 AM

Applications that experience periodic compression cycling over time may require a gasket that is capable of compression rebound. In the event that your application uses a material that does not resist compression force, the material may depreciate over time. When your gasket has dwindled or has deteriorated from all of the periodic compression cycling, your gasket will become ineffective and will need to be replaced. In a perfect world, your gasket should rebound to fill any potential gaps. Using a material with great compression resistance will guarantee a long-term sealing performance that will work just as effectively each time you reseal your application.
