DURABLE COVERING FOR CHEMICAL PROTECTION

摘要

A protective covering is described comprising at least one microporous film attached to a functional layer, the protective covering capable of inhibiting the passage of toxic substances therethrough. Preferably the functional layer is an adsorptive layer contained between two oleophobic, microporous films. Additional shell and backer layers may be added to the construction forming a protective covering having good durability, flexibility and high moisture vapor transmission.
