Urethane (yor'-a-thay'-n)
1. Open cell ether or ester urethane foams, excellent for weatherstripping applications.
Foamtapes.net urethane foams make great weatherstripping products where gasketing is not needed. Comes in both ether and ester varieties:
- Ether
- Low density (1.2 lb./ft3) light grey foam with very good compression recovery. Ideal for weatherstripping applications that do not involve high UV exposure amounts and where compression recovery is essential.
- Ester
- Low density (2.0 lb./ft3) charcoal grey foam. Has a "crispier" feel than ether and also provides better UV resistance
