Why s Polycarbonate Sheet the Preferred Material for Oxygen Chambers and Locomotive Windows?

Polycarbonate sheet, also known as PC sheet, has become the preferred material for high - strength and high - requirement application scenarios such as oxygen chambers and locomotive windows due to its unique performance advantages.  

I. Superior Physical Properties

1. High Strength and Impact Resistance: Polycarbonate sheet has a relatively high impact strength and can withstand large external impact forces without being easily broken. This characteristic gives it a significant advantage in situations where the locomotive window may be subject to impact.  

2. Good Heat Resistance: Polycarbonate sheet can be used for a long time between - 100°C and 130°C, and its embrittlement temperature is below - 100°C, having good heat - resistant properties. This enables it to maintain stable physical properties under extreme temperature conditions, suitable for high - temperature or low - temperature environments such as oxygen chambers.

3. Lightweight: The density of polycarbonate sheet is relatively low, and its weight is only about one - third of that of silicate glass, making it an ideal choice for lightweight design. In situations where weight needs to be reduced, such as locomotive windows, the application of polycarbonate sheet can significantly reduce the overall weight and improve operational efficiency.

II. Excellent Optical Properties

1. High Transparency: The transparency of polycarbonate sheet can reach 90% and it is known as "transparent metal". This characteristic enables it to meet the high - transparency requirements in situations such as oxygen chambers and locomotive windows, ensuring a clear view.

2. Good Optical Stability: Polycarbonate sheet is not easy to age and turn yellow during long - term use and can maintain stable optical properties.  

III. Good Processing Properties

1. Easy to Cut and Shape: Polycarbonate sheet can be easily cut with a standard circular saw and is easy to be processed into various shapes and sizes. This makes it more flexible and convenient during the manufacturing process and can meet the customized requirements of different situations. 

2. Easy to Install: Polycarbonate sheet is six times lighter than standard glass sheets, and its installation is faster and easier. At the same time, because it has good toughness and impact resistance, it is not easy to be damaged during the installation process, reducing the installation cost.  

IV. High Safety

1. Explosion - proof Performance: Polycarbonate sheet is not easy to break when subjected to external impact forces and can effectively prevent fragments from splashing and hurting people. This characteristic gives it a significant advantage in situations where high safety is required, such as locomotive windows.  

2.Fire - proof Performance: Depending on the choice of particles, polycarbonate sheet can have fire - proof performance. This makes it more safe and reliable in situations where fire - proof measures are required, such as oxygen chambers.  

In conclusion, due to its superior physical properties, excellent optical properties, good processing properties and high safety, polycarbonate sheet has become the preferred material for high - strength and high - requirement application scenarios such as oxygen chambers and locomotive windows.
