Technical data
Physical properties and test methods for Dragon Jacket prefabricated pipe insulation and high-density pipe support inserts.
Physical properties
Pipe insulation uses a 2 lb polyisocyanurate core. High-density inserts at supports, hangers and other load points use 4, 6 or 8 lb polyurethane cores. Every core is encapsulated in the same polyurea jacket.
