"Large
Particle Spacer" is made of a cross-linked co-polymer resin of divintylbenzene,
which is transparent and rigid, and has true sphere shape.
The product has the same high quality as the spacer for LCD, i.e.:
* Very sharp particle diameter distribution,
* Excellent thermal stability and
* Excellent chemical resistance,
The above qualities are due to our unique technology of the LCD spacer,"Micro-pearl
SP".
The Large Particle Spcer is favorably accepted as the spacer for automotive
and optical instruments. |

|
1)The spacer keeps the
gap constant and even.
2)With its excelent high and low temperature resistance, it functions
perfectly between -40 and 200
to hold
the designed gap.
3)Particles are in true sphere shape.
4)They are transparent.
We will supply, on request, conductive particles made by depositing
conductive layer opver the Large Particles Spacer. |
