When it comes to safety, there are a lot of requirements that aircraft must meet to create a reasonably prepared environment for emergencies. Fire extinguishers are a common safety protocol in most public places, and a passenger aircraft is no exception. In fact, a strict passenger to portable fire extinguisher ratio must be maintained within most aircraft. Extinguishers are stored in both the cabin and the flight deck, and a variety of materials are used depending on the severity of the fire. This blog will cover the different types of extinguishing agents as well as the ideal situation in which each should be used in flight. Read more >>

 In aerospace and military missions, many important functions rely on printed circuit boards (PCBs) to provide electricity. A malfunctioning PCB can jeopardize an entire flight, so it is important to make sure the PCB can withstand harsh situations. Environmental exposure can lead to issues such as corrosion, so PCBs are manufactured with a conformal coating to protect the exposed components on the surface of the board. A conformal coating is a thin, clear polymeric film that coats the board’s surface and ultimately ensures a longer working lifespan. Conformal coatings are used across many fields, but different environments demand different forms of protection. For this reason, it is important to make sure the correct material is chosen for the coating. Read more >>

While all fasteners are prone to wear and deterioration throughout their operational lifespan, several preventative measures can be implemented to delay this occurrence. Installing components slowly, avoiding dirty threads, and using lubricants are all essential steps in combating early attrition. Another technological development that has significantly contributed to increased fastener lifespans is anti-seize, which is a compound that targets several of the hallmarks associated with fastener wear. In this blog, you will find a definitive guide to anti-seize, in which we will discuss its function and how to apply it to your application.

Agitators are an essential element in a wide variety of industrial applications. While agitators are diverse in their design and size, they all work to stir or shake an object or substance in order to achieve homogeneity or promote some other goal that can only be achieved through motion. In this blog, we will discuss everything you need to know about agitators and their use in different industries. Read more >>

When a system requires efficient cooling for its optimal performance and protection, there are various solutions that may be used. For many assemblies, the heat exchanger is a perfect option, coming in the form of a device which transfers heat between mediums with high speed and efficiency. The way in which heat exchangers work is through the basic flow of heat and thermodynamics, allowing heat to move from a hot medium to a cooler one without the need for any physical contact or intermixing for the process to be done. Heat exchangers can be found in various applications, often being placed within refrigeration equipment, aircraft air systems, radiators, chemical processing assemblies, and much more. In this blog, we will provide a brief overview of the most common heat exchanger types, allowing you to have a better understanding of your options and how they function. Read more >>
