With the continuous development of modern technology, PTFE waterproof and breathable membrane has become an indispensable and important material in various fields. Especially in the fields of outdoor sports, military equipment and industrial manufacturing, the application of this film is extensive and important. To evaluate the performance standards of different products, an IP rating system is often adopted. In this article, we will focus on its two common standards, IP68 and IP69.
To understand the difference between IP68 and IP69, we need to first understand the basic principles of the IP rating system. The IP rating system is set in accordance with the standard IEC 60529 and is used to identify and evaluate the protection level of electronic products. Among them, the number 6 indicates the dustproof level, and the numbers 8 and 9 indicate the waterproof level respectively.
In terms of dust resistance, there is not much difference between IP68 and IP69. They all have a very high level of dust resistance, which means that the PTFE waterproof and breathable membrane can protect products from the intrusion of dust and foreign objects in harsh environments. Therefore, whether it is IP68 or IP69, it can well protect the internal electronic components from dust.
In terms of waterproof level, there are some differences between IP68 and IP69. The IP68 rating indicates that the PTFE waterproof and breathable membrane has waterproof properties and can withstand long-term immersion in water. The IP69 rating is more demanding, which means it can withstand the impact of high-pressure and high-temperature water flow under harsh conditions. This means that the IP69 rating is more suitable for dealing with harsh industrial and outdoor environments, such as high-pressure sprays, cleaning and even stone impacts.
In addition, IP69-rated PTFE waterproof breathable membrane usually has good chemical corrosion resistance and can be used in corrosive liquid environments for a long time without losing its protective capabilities.
In summary, the IP68 and IP69 ratings of PTFE waterproof breathable membrane are evaluated based on its dustproof and waterproof capabilities. The IP69 rating can not only protect electronic products from dust in harsh environments, but also withstand the impact of high-pressure and high-temperature spraying and cleaning. Therefore, when selecting, it is necessary to select the appropriate grade according to specific application requirements to ensure product reliability and durability.
