The diffusion coefficient and solubility coefficient are the ingredients that makeup permeability. values typical for a variety of base polymers’ water permeability. Average water vapour permeability [g/ (day.m 2)] through 25-micron films at 38 °C and 90% relative humidity.
When applied to the surface of stealth military aircraft like the F-22 Raptor and F-35 Lightning II, radar-absorbing material reduces the radar cross-section, making the aircraft difficult to detect by radar.
Radar-absorbing substance polymers. The most popular method for locating and tracing aircraft is radar. Although radar is a crucial instrument in managing air traffic, it poses a challenge in offensive military operations because aircraft must strike their objective and then flee without being noticed.
In radar, electromagnetic waves are sent into the atmosphere and subsequently returned to a receiving antenna by reflections off of the aircraft.
The Global Radar permeable polymer market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Advanced driver assistance systems (ADAS) and enabling sensors are being installed in increasing numbers in modern vehicles. All road users are safer thanks to ADAS, which is also laying the groundwork for totally and extensively automated driving.
According to an ADAS expert from Lanxess’ High-Performance Materials (HPM) business unit, “ADAS radar sensors and their housings, in particular, are an appealing field of application for our polybutylene terephthalate (PBT) and polyamide compounds.
They offer a wide variety of products that are in line with the necessary technical specifications in this field. These include great mechanical qualities for securely and reliably attaching the sensors to the vehicle, outstanding radar transparency and dimensional stability, good laser welding behavior, and more.
SABIC keeps working to create specialized materials that can improve sensor accuracy and dependability in order to promote technological innovation in the radar sensor industry, which is expanding quickly.
Comparing expanding selection of LNP compounds to radar-absorbing materials made for military applications, they see potential cost savings as well as excellent radar wave absorption.
