Die cut foils are flexible, formable materials that provide heat shielding, sound deadening, sealing, and insulation. They are made of thin-gauge metals and used in the automotive, HVAC, and appliance industries. Aluminum foils support precision die cutting and can be embossed and/or micro-perforated. These die cut foils can be laminated to thermal insulation, and supplied with or without an adhesive backing.
Choosing the right die cut insulation can be challenging. Product designers understand an application’s requirements, but sourcing managers are tasked with finding a die cutter who can recommend and then convert the right insulating materials. In this week’s blog entry, the second in a winter-long series from JBC Technologies, we’ll take a closer look at die cut insulation. If you missed last week’s introduction, click here for an overview of the materials we’ll cover.
What can home improvements teach us about the importance of thermal insulation in product design? During a recent remodeling project, an electrician removed an old light fixture from above a bathtub. The general contractor then removed the rest of the ceiling and made an unwelcome discovery. As the contractor explained to the homeowner, the 2 x 4s that surrounded the old light fixture had large black spots that weren’t pine knots. The bathroom hadn’t gone up in flames, but the burn marks were alarming.
Thermal interface materials (TIMs) play an important role in the electronics manufacturing industry. Electronic components generate heat. Excess heat needs to be discharged or the life of the electronic device could be drastically shortened. Typically, fans and heat sinks (and heat sink fans) are used to dissipate heat in electronic devices, but as electronics mature, so do the materials used to construct them. Some of these thermal interface materials include:
