PMI foam company Cashem ‘cashes in’ on the multi-use of its product in all kinds of industries…

Cashem Advanced Materials Hi-tech Co Ltd was established in 2010, and now becomes the first company to specialise in manufacturing PMI foam in China. Backed by the technology of the Institute of Chemistry and The Chinese Academy of Science(ICCAS), Cashem – our latest IMD online member  – has an established highly-qualified R&D team, formed to focus on the industrialisation and serialisation study of the PMI foam product.

widely used

Cashem products are very widely used in leading industries such as Aerospace, Radar, Railways, Shipping and Aviation  Check our their blogging information below on how Cashem foam is also used in numerous more general ‘daily life’ type industries, including Sports Equipment; Medical Apparatus; Unmanned Aerial Vehicles – the drone …and indeed Wind-power…

Sports Equipmen

Composites made of carbon/glass fiber and foam cores have become the new choice for the sports equipment. The rigid and strong PMI foam is an ideal material for lightweight products because it can provide the high specific strength. The capacity of obtaining complex geometry shapes by thermoforming or CNC also make it to achieve the mass production.

Under the heat and pressure, durable composites parts, which have extremely low weight but high strength, can be obtained by the PMI foam and fiber with different kinds of resins. These composites are perfectly suited for sports equipments such as bicycle wheels, skis, rackets and surfboards. It is helpful for the athlete to challenge the limits of human beings.

Medical Apparatus

X-ray and CT scans are used in the clinical diagnosis to inspect the body, in order to obtain the high definition images, increasing the dose of radiation is adapted, but the exposure to radiation has big risk of developing cancer or other diseases.

PMI foam owns lower aluminium equivalent, it means it can get sharper image under smaller dose of radiation, X-ray and CT scans tables, which use PMI as the sandwich structure foam core, dramatically reduces the radiation exposure in diagnostic procedures. Besides the protection for patients against the radiation, high specific strength of PMI foam makes the medical beds conveniently handled by the operator.  

Unmanned Aerial Vehicles 

An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without a human pilot aboard. The flight of UAVs may operate with various degrees of autonomy: either under remote control by a human operator or autonomously by onboard computers.

UAV originated mostly in military applications, their use is rapidly expanding to commercial, scientific, recreational, agricultural, and other applications, such as policing, peacekeeping, and surveillance, product deliveries, aerial photography, agriculture, smuggling, and drone racing. The challenge right now is how to extend its flying range, composites with PMI foam as the sandwich structural core can dramatically reduce the weight of the UAV and offer excellent mechanical properties.

Wind-power

Current, Onshore blades have the lengths up to 60 meters, and the length of offshore blade can even reach to 100 meters. The increase length undoubtedly will increase the loads of the blade, which place higher structural demand for the other components. So the weight reduction of the blade is becoming more and more important.

Comparing to other foam core, PMI can provide the same mechanical properties with low density, which can reduce the weight of the composites components sharply, and because of its fine cell size, resin uptake is also less.
