Decoding the Lexan 920a Datasheet A Comprehensive Guide
The Lexan 920a datasheet provides a wealth of information regarding the physical, mechanical, thermal, and electrical properties of this remarkable material. Think of it as a blueprint that allows engineers and designers to make informed decisions about whether Lexan 920a is the right choice for their specific project. Its purpose is to provide standardized test results and performance metrics, allowing for easy comparison with other materials and ensuring predictable behavior in real-world applications.
How is this information used? Primarily, engineers and product developers rely on the datasheet to assess whether Lexan 920a meets the required performance criteria for their intended use. This includes evaluating its resistance to impact, its ability to withstand high temperatures, its optical clarity, and its electrical insulation properties. For example, a designer creating protective eyewear would be very interested in the material’s impact resistance and optical clarity, while an engineer designing electrical enclosures would focus on its dielectric strength and flammability rating. Understanding the data helps avoid costly mistakes down the line.
The datasheet typically presents information in a structured format, often including sections such as:
- General Properties: Density, specific gravity, water absorption
- Mechanical Properties: Tensile strength, flexural modulus, impact strength (Izod, Gardner)
- Thermal Properties: Heat deflection temperature (HDT), Vicat softening point, coefficient of thermal expansion
- Electrical Properties: Dielectric strength, dielectric constant, volume resistivity
- Optical Properties: Light transmission, haze
Often this information is compared to industry standards. For example, impact resistance is usually measured using Izod or Gardner impact tests, and the results are presented alongside the relevant ASTM standard number. Similarly, flammability is often rated according to UL standards. Many datasheets also include information on processing recommendations, such as suggested molding temperatures and pressures, helping fabricators optimize their manufacturing processes. A small sample table is as follows:
| Property | Value | Unit |
|---|---|---|
| Density | 1.20 | g/cm³ |
| Tensile Strength | 65 | MPa |
