Biofuels present significant challenges when specifying seals. Trelleborg Sealing Solutions delivers elastomer sealing solutions intended specifically for biofuels to help processors prepare themselves for the first-generation energy revolution. The company uses a traffic light matrix to rate materials for their suitability with biofuels. There are five criteria to consider:
- Hardness.
- Tensile strength.
- Ultimate elongation.
- Change in weight.
- Change in volume.
