Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
52 words
A method of making a material for use in the encapsulation of electrical components by making a blend consisting essentially of poly(phenylene sulfide), about 30 to 70% by weight of inorganic filler and organotitanate in an amount of from about 0.5 to 5% by weight of the inorganic filler in the blend.
Claim 2
Independent Claim
52 words
A method of making a material for use in the encapsulation of electrical components by making a blend consisting essentially of poly(phenylene sulfide), about 30 to 70% by weight of inorganic filler and organotitanate in an amount of from about 0.5 to 5% by weight of the inorganic filler in the blend.
Claim 3
Dependent Claim
24 words
The improved method in accordance with claim 1 wherein the amount of organotitanate is 1.3% by weight of the inorganic filler in the resin.
Claim 4
Dependent Claim
15 words
