Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
99 words
A polymeric material particularly adapted for use in a high pressure, elevated temperature molding process comprising a substantially uniform mixture of a) about 20% to about 90% solid, flowable, particulate silicone rubber having a nominal flow rate of at least 0.6 gram/second through a 1.1 cm diameter pipe 7.6 cm long under applied pressure of 10.34 MPa at room temperature; and b) about 10% to about 80% thermally conductive particulate metal 1) having a melting point less than about said molding temperature; and 2) substantially chemically compatible with said silicone rubber; resulting in a thermally conductive flowable pressurizing medium.
Claim 2
Dependent Claim
99 words
A polymeric material particularly adapted for use in a high pressure, elevated temperature molding process comprising a substantially uniform mixture of a) about 20% to about 90% solid, flowable, particulate silicone rubber having a nominal flow rate of at least 0.6 gram/second through a 1.1 cm diameter pipe 7.6 cm long under applied pressure of 10.34 MPa at room temperature; and b) about 10% to about 80% thermally conductive particulate metal 1) having a melting point less than about said molding temperature; and 2) substantially chemically compatible with said silicone rubber; resulting in a thermally conductive flowable pressurizing medium.
Claim 3
Dependent Claim
26 words
the polymeric material particularly adapted for molding as recited in claim 1 wherein said particulate metal is about 0.005 mm to about 0.5 mm in size.
Claim 4
Dependent Claim
19 words
The polymeric material particularly adapted for molding as recited in claim 1 wherein said particulate metal comprises eutectic alloys.
Claim 5
Dependent Claim
25 words
The polymeric material particularly adapted for molding as recited in claim 1 wherein said particulate metal comprises lead, tin, zinc, bismuth or a mixture thereof.
Claim 6
Independent Claim
118 words
A method of molding an article precursor into an article at an elevated temperature comprising a) placing an article precursor within a pressure vessel; b) substantially filling the vessel with a substantially uniform mixture comprising 1) a solid flowable polymer medium; and 2) thermally conductive particulate metal having a melting point less than about said elevated temperature and substantially chemically compatible with said polymeer; c) exposing said mixture disposed in close proximity to said article to a temperature equal to or greater than said melting point; and d) causing said mixture to produce a substantially uniform, predetermined medium pressure on the surface of said article precursor. whereby the thermally conductive particulate metal transfers heat to the article precursor.
Claim 7
Independent Claim
118 words
A method of molding an article precursor into an article at an elevated temperature comprising a) placing an article precursor within a pressure vessel; b) substantially filling the vessel with a substantially uniform mixture comprising 1) a solid flowable polymer medium; and 2) thermally conductive particulate metal having a melting point less than about said elevated temperature and substantially chemically compatible with said polymeer; c) exposing said mixture disposed in close proximity to said article to a temperature equal to or greater than said melting point; and d) causing said mixture to produce a substantially uniform, predetermined medium pressure on the surface of said article precursor. whereby the thermally conductive particulate metal transfers heat to the article precursor.
Claim 8
Dependent Claim
33 words
A method of molding an article precursor into an article at an elevated temperature as recited in claim 5 wherein said particulate metal is about 0.005 mm to about 0.5 mm in size.
