Abstract:
A free-standing solid composite intumescent structure has at least one bendable metal mesh, preferably at least two, secured on or in a bendable intumescent sheet material. The structure is bendable by a bending force into a shape at a temperature above -10°C while retaining the bended shape when the bending force is removed. The intumescent sheet material has 10 wt% or more, based on total weight of the sheet material, of a polymeric resin; inorganic filler; and, an intumescent component. Fire protection barriers can be made from the free-standing solid composite intumescent structure, which can be used in fire protection systems where the fire protection barrier is installed on a substrate, for example steel building elements.
Abstract:
The present application relates to an adhesive tape for conduits, conduits and methods of making conduits. In one aspect, the present application relates to an adhesive tape comprising a final tensile strength of at least about 80% of the initial tensile strength after being submitted to salt water a temperature of about 60°C for 21 days. In some embodiments, the adhesive tape comprises a final tensile strength of at least 80% the initial tensile strength after being submitted to salt water at a temperature of 90°C for 21 days. In another aspect, the present application relates to a conduit comprising enclosed conveying means and the adhesive tape adhered to the enclosed conveying means. In yet another aspect, the present application relates to a method of making an conduit comprising the steps of providing an enclosed conveying means, and adhering the adhesive tape to the enclosed conveying means.
Abstract:
A solid intumescent material is made of a of about 30 wt% or less, based on total weight of the intumescent material, of a hot melt thermoplastic or elastomeric resin (e.g. an EVA resin), a reinforcing material (e.g. glass fibers having an aspect ratio of at least about 100), inorganic filler and an intumescent component (e.g. ammonium polyphosphate, pentaerythritol and melamine). The intumescent material may be formed into fire protection barriers of various thicknesses and may be shaped at a temperature well below the activation temperature of the intumescent material to permit conforming the barrier to requirements at a job site.
