| in Hardness | B | 91 | 98 | 91 | 98 | +7.7 | +7.7 |
Based on the above tests and results at 400 F, the rubber becomes harder while losing a small amount of both mass and volume.
Based on the above tests and results at 500 F, the rubber becomes harder while losing about 10 % of both mass and volume.
