1. optical properties

Parylene absorbs very little in the visible light range, making it transparent and colorless. Colorless and transparent films can be used for optical devices, erasable optoelectronic storage devices, and electrostatic copying devices. At temperatures below 280 microns, both Parylene N and C exhibit strong absorption. All Parylene has relatively no characteristics at wavelengths of at least 60 microns (except for some peak characteristics).

2. radiation tolerance

在真空中，Parylene N和C薄膜表现出很高的抵抗伽玛射线衰变的能力。张力和电气性能在1.6Mr/h的剂量率下加到100Mr之后仍旧保持不变。Parylene N和C在室内稳定，建议不要在室外阳光直接照射的环境下长期使用。室外使用建议用Parylene F4和F8。
