Moldable composition

Claim 2

A moldable composition for use in making bulk deformable sealing members for articles comprised of: a mixture of a. a major amount of an elastomeric material; b. an amount of filler material at least 30 parts per hundred by weight of said elastomeric material; c. an amount of a catalyst sufficient to polymerize said elastomeric material; and d. an amount of oil of between 2.5 and 20 parts per hundred by weight of elastomeric material, said oil being incompatible with said elastomeric material; said moldable composition when molded yielding a test member having a Shore A hardness of between 30 and 95, preferably between 50-65 when measured in accordance with ASTM D-2240, whereby after molding a sealing member from said mixture, said incompatible oil blooms to surface portions of said sealing member resulting in said surface portions of said sealing member having inherent lubricity.

Claim 3

The moldable composition as set forth in claim 1 wherein said elastomeric material has a precursor selected from the group consisting of chloroprene, epichlorophydrin, silicone and an ethylene-acrylic copolymer.

Claim 4

The moldable composition as set forth in claim 1 wherein said elastomeric material has a chloroprene precursor.

Claim 5

The moldable composition as set forth in claim 3 wherein said elastomeric material is neoprene and said incompatible oil is a paraffinic oil.

Claim 6

The moldable composition as set forth in claim 1 wherein said mixture is further comprised of an amount of wax of betwen 0 and 10 phr said wax being incompatible with said elastomeric material.

Claim 7

The moldable composition as set forth in claim 4 wherein said mixture is further comprised of an amount of paraffinic was of between 0 and 10 phr said wax being incompatible with said elastomeric material.

Claim 8

The moldable composition as set forth in claim 1, wherein said mixture is further comprised of an amount of processing additives between 15 and 26 phr wherein said processing additives facilitate processing and molding of said mixture.

Claim 9

The moldable composition as set forth in claim 7 wherein said processing additives comprise one or more of the following: processing oils, release agents, accelerators and scorch retarders.

Claim 10

The moldable composition as set forth in claim 1 wherein said mixture is further comprised of an amount of stabilizing additives between 4 and 9 phr wherein said stabilizing additives prolong the in-service life of articles molded from said mixture.

Claim 11

The moldable composition as set forth in claim 9 wherein said stabilizing additives comprise one or more of the following: antiozonants, antioxidants, and antidegradants.

Claim 12

An assembly comprised of a first and a second article, and a sealing member molded from the composition of claim 1, wherein said sealing member is sealingly disposed between and against said first and second articles and wherein at least one of said first and second articles has surface portions for frictionally engaging respective surface portions of said sealing member during movement therealong, while assembling said first and second articles and said sealing member, whereby said inherent lubricity of said surface portions of said sealing member reduces the coefficient of friction between said article surface portions and said sealing member surface portions.

Claim 13

An assembly as set forth in claim 11 wherein said sealing member is a wire seal and said first article is an electrical conductor and said second article is a dielectric housing of an electrical connector for said electrical conductor wherein said sealing member surrounds said eletrical conductor and is disposed in a cavity of said housing wherein a terminated end of said electrical conductors is secured.

Claim 14

An assembly as set forth in claim 11 wherein said sealing member is an annular seal and said first article is a first dielectric housing having a forward plug section around which said annular seal is disposed and said second article is a second dielectric housing having a forward hood section for axially receiving said plug section of said first housing during axial mating thereof.

Claim 15

A sealing member for an article, said sealing member being bulk deformable and molded from a moldable composition comprised of: a mixture having: a. a major amount of an elastomeric material; b. an amount of filler material at least 30 parts per hundred by weight of said elastomeric material; c. an amount of catalyst sufficient to polymerize said elastomeric material; and d. an amount of oil between 2.5 and 20 parts per hundred by weight of elastomeric material, said oil being incompatible with said elastomeric material; said moldable composition when molded yielding a test member having a Shore A hardness of between 30 and 75, preferably between 50-65 when measured in accordance with ASTM D-2240; whereby after molding said sealing member from said mixture, said incompatible oil blooms to surface portions of said sealing member resulting in said surface portions of said sealing member having inherent lubricity.

Claim 16

A sealing member for an article, said sealing member being bulk deformable and molded from a moldable composition comprised of: a mixture having: a. a major amount of an elastomeric material; b. an amount of filler material at least 30 parts per hundred by weight of said elastomeric material; c. an amount of catalyst sufficient to polymerize said elastomeric material; and d. an amount of oil between 2.5 and 20 parts per hundred by weight of elastomeric material, said oil being incompatible with said elastomeric material; said moldable composition when molded yielding a test member having a Shore A hardness of between 30 and 75, preferably between 50-65 when measured in accordance with ASTM D-2240; whereby after molding said sealing member from said mixture, said incompatible oil blooms to surface portions of said sealing member resulting in said surface portions of said sealing member having inherent lubricity.

Claim 17

A sealing member as set forth in claim 14 wherein said sealing member is a wire seal.

Claim 18

A sealing member as set forth in claim 14 wherein said sealing member is an annular seal.

Claim 19

A sealing member as set forth in claim 14 wherein said moldable composition is further comprised of an amount of wax of between 0 and 10 phr said wax being incompatible with said elastomeric material. s
