The present invention relates to a method of preparing green form polystyrene resin. More specifically, recyclable expandable material from general waste is made use of along with virgin expandable material and virgin hardening polymer for preparing green form polystyrene resin. Further, extruding the mixture yields green form compounded polystyrene resin with high melt flow index or gas injection into the green form compounded polystyrene resin results in synthesis of green form expandable capsules or beads thereof with desired properties. The present invention further facilitates the production of polystyrene molded foam used for insulation by puffing expandable green form capsules with pre-expander.

Systems and methods for improving adhesion of an insulating foam to a molded polymeric insulating structure through use of ozone gas for functionalization of molded polymeric surfaces of an internal cavity of the insulating structure.
摘要:
A method of coating a field joint and a coated field joint formed thereby. The field joint coating includes a first thermal insulation material injection molded over the uncoated field joint to form a first layer, and a second thermal insulation material injection molded over the first layer to form a second layer. The second material has a greater flexibility than the first material and a lower maximum operating temperature than the first material. In certain embodiments, the second material forms a significant part of the volume of the field joint coating.

摘要:
A thermal/acoustic insulation product, such as for an aircraft, comprising a block of flexible, open-celled, cellular foam having a predefined shape and having a thermoformed amorphous film covering that completely envelops the foam block. A process for making the insulation product includes first cutting the block of foam to a predefined shape, such as a shape suitable for placement in an area of an aircraft in need of insulation. Then, a first sheet of film is heated to its melt point and conformed to a first surface area of the block, and a second sheet of film is heated to its melt point and conformed to a second surface area of the block, wherein the first film and the second film are joined to one another at one or more seams. The insulation product may then be installed in an aircraft.
摘要:
The present invention relates to A process for producing of an insulation component in which an insulating foam material is placed in a mould and in which (a) isocyanates, (b) polymeric compound having hydrogen atoms reactive towards isocyanate, (c) optionally chain extenders and/or crosslinkers, (d) catalysts and optionally (e) other assistants and/or additives are mixed to give a reaction mixture and the reaction mixture is injected into the mould and cured to form an seamless outer material enclosing the insulating foam wherein the average functionality of the polyols (b) and the chain extenders and/or crosslinkers (c) and the isocyanates (a) is more than 2.2. The invention further relates to an insulation component obtainable by such a process and the application of that insulation component as door or wall component for a cold storing device.
