Silicone rubber materials and some plastic films have chemically inert and non-porous surfaces, which equates to low surface energy. This means they have a weak molecular bonding force making it difficult to create a bond with many pressure sensitive adhesives.

Silicone Rubber, a "Low Surface Energy" Elastomer, what does this mean?
Silicone is a high performance elastomer with the ability to withstand extreme temperatures, both high and low. It also naturally repels, which makes it an excellent choice for a water seal or a moisture barrier. However, this also makes silicone tricky to bond to other surfaces.

IP Rated Enclosures: Venting Solutions
Sensors, controllers and other electronic elements are being integrated into devices across virtually every industry. Many of these products are made for use in conditions where they may be exposed to extreme temperatures, rain, wind, dust, and moisture. (See application story about "smart" shipping pallets linked at the bottom of this post.) Designing such products requires that the container or enclosure holding the electronic components be completely sealed. Exposure to harsh elements could cause a product failure.

Custom Die-cut Parts for Automated Assembly
Among numerous assembly options, automated assembly is often the method of choice for many of our customers. Automated placement is used for projects with very high volumes where precise placement is critical. Automated assembly can also significantly increase assembly speed and efficiency.
Marian designs and manufactures custom components to fit seamlessly into our customers’ automated assembly process. We can modify many different aspects of the final part and packaging from liner type, part spacing and orientation, and quantity of parts per roll.

Improvements are being made to the lithium-ion batteries used in electric vehicles. Car makers are developing more powerful lithium-ion batteries that have increased range and charge more rapidly. Along with these improvements, enhancing safety is becoming increasingly urgent for electric vehicle development. As mentioned in our previous blog post, 11 Considerations when Selecting Thermal Interface Materials for Electric Vehicle Li-Ion Batteries, Li-ion batteries produce a significant amount of heat while in use and while charging. Along with the use of thermal management materials, placing protective engineered flame retardant insulating materials between the components of the battery cell, module, and pack can offer additional thermal and electrical insulating protection. However, adding such materials can be challenging due to space and weight constraints.
In this post we outline four materials that can enhance the safety of lithium-ion batteries used in electric vehicles. Some shared characteristics of these four materials are listed below.
- ultra-thin
- light weight
- electrically and thermally insulating
- flame retardant
- can be die-cut and laminated with PSA
