The hardened molecular sieve catalyst is highly attrition resistant.

A friction-resistant coating is on at least one of the faces.

The flanges of wheels are embodied in the form of a separate element made of antifrictional material.

Usually one finds in the trade class 2 (scrub resistant) and class 3 (wash resistant).

The delivery line (22) preferably includes a friction resistant inner layer, an intermediate dielectric layer and a protective outer layer.

Most advantageously, the material of the insole is porous paper that withstands friction or material with 50 % viscose and 50 % polypropylene.

A friction-resistant coating (40) is applied between components of the assembly to mitigate wear and to prevent bending and twisting.

The subject invention pertains to large particle size, attrition-resistant, continuous, but wrinkled, high surface area aqueous fluid absorbent polymers, preferably of a crosslinked acrylic acid or acrylate.

The present invention relates to abrasion-resistant, anti-friction tubing formed from such composites, and to uses of such tubing as a liner for flexible, motion transmitting cable assemblies.

The elastic member (21) engages a friction-resistant bearing surface on the bearing support (22) in response to a bending of the elastic member (21).

The invention relates to a semiconductor chip having a protective layer (6,8) made of an abrasion-resistant and/or etch-resistant material applied thereto.

A method for the manufacture of a sorbent composition having an attrition-resistant coating suitable for use in the removal of hydrogen sulfide from sulfur-containing fluid streams.

The latex impregnated side of the paper maintains increased strength making the paper resistant to scuffing while at the same time, the roughened side of the paper improves its adhesiveness to joint compounds (12).

It is highly resistant to friction, so it supports better the daily tear and wear, and lengthens the life of the product, keeping it in good condition.
