| The physical properties of the SILKS engraving material are largely controlled
by the base material. This material was chosen to provide a good balance of properties
for this product to satisfy a wide range of uses. |
| The material softens at about 200°F (93.33°C) sufficiently so that it can be bent
where needed. It can be drilled, sawed, sheared, nailed, bonded and die-cut. |
| The material was tested for flammability by Underwriters Laboratories. It is rated 94 HB on the UL 94 test. |
| Most of the colors will exhibit slight fading under prolonged exposure to direct sunlight.
There are, however, those which tend to fade more severely. This material is designed for use
where no direct extreme exposure is encountered. |
