Test Glassine Transmittance by Diffuse Transmission Material Transmittance Meter
The sample received from the customer several days ago is a kinds of white thin paper that requires testing its transmittance. Consult the customer only to know that this kind of paper is called Glassine, the customer has got the date of 65% transmittance with an ordinary transmittance meter, but in fact if we use LS117 diffuse transmission material transmittance meter with integrating sphere function,the test result is 86.5. why the data difference is so large?
This kind of white GLASSINE paper is diffuse transmission material. The ray incident on the surface is diffused at many angles.Sp we must use the diffuse transmission meter with integrating sphere function to test the transmittance of it.
LS117 Diffuse transmission material transmittance meter is an instrument with integrating sphere function, which has the characteristics of high precision, simple operation and obvious measurement. It is especially suitable for testing the transmittance of all kinds of diffuse transmission materials, such as milky white Glassine, foggy, matte wool surface, Zirconia, translucent lampshade,PC material and so on.
Glassine is a smooth and glossy paper that is air, water and grease resistant. It is translucent unless dyes are added to color it or make it opaque.Glassine is most commonly used as a base for further silicone coating for manufacture of release liner. Glassine is also employed as an interleaving paper in bookbinding, especially to protect fine illustrations from contact with facing pages; the paper can be manufactured with a neutral pH, and can prevent damage from spilling, exposure, or rubbing. Glassine adhesive tape has been used in book repair. In chemistry, glassine is used as an inexpensive weighing paper. It is used in foodservice as a barrier between strips of products (for example: meat, baked goods). Glassine is resistant to grease and facilitates separation of individual foodstuffs.
