SARAN™ 540-CX Vapor Retarder Film is composed of a film of the barrier polymer polyvinylidene chloride (PVDC) coextruded with other specialty polymers that provide strength and support. Working together, the portions of this coextruded film combine to create a vapor retarder and jacketing material for mechanical insulation systems that is durable, flexible and has excellent resistance to water vapor penetration. SARAN 540-CX Film is designed specifically to help prevent water absorption and strongly resist moisture vapor drive into the insulation. A permeance rating of 0.02 perms meets or exceeds standard industry requirements for vapor retarders in cold service. SARAN 540-CX Vapor Retarder Film is not a known nutrient source for mold or mildew.
