MASTIC WHSS 80 C PRODUCT DESCRIPTION
WHSS 80 C sleeves consist of a radiation cross-linked heat shrinkable backiņg, coated on the inside with a heat Activated adhesive. While the modified polyethylene material of the backing offers superior mechanical protection, the specially formulated adhesive offers excellent corrosion protection under demanding conditions. As 3 PE system, it is convenient for construction. The system is suitable for most of the common pipeline coatings like PE,
PP, FBE etc.
