Ensolite Foam (IV1, IV2, IV3, MLC)

Material selection is never a small decision in aerospace, automotive, and marine work, where safety and compliance carry real weight. Bramport Supply Co. offers Armacell Ensolite foam, a trusted line of elastomeric closed-cell foams engineered to perform in the demanding interiors of the transportation industry. Available in IV1, IV2, IV3, and MLC grades, this versatile material gives fabricators and upholsterers a dependable option for cushioning, padding, and sealing.

Ensolite closed-cell foam is valued for its resistance to oil, fuel, and water, making it well-suited for both indoor and outdoor applications across a wide temperature range. It is commonly used as carpet padding, cushioning for seat components, and material for headliners and sidewalls, and it also performs well in gasketing and sealing applications. With its water-resistant characteristics, an Ensolite pad is a practical choice where moisture is a concern.
