摘要:
In one aspect, the invention relates to crosslinkable, flame retardant polymer compositions are provided comprising a polyamide or polyester; a flame retardant system; a crosslinking agent; and a flame retardant system coagent. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
摘要:
Disclosed herein is a composition comprising a crosslinked organic polymer; wherein the composition has a coefficient of friction that is in a range of ±30% of a coefficient of friction for a composition comprising the same organic polymer that is not crosslinked; and wherein the composition has a lower K factor than a K factor of the composition comprising the same organic polymer that is not crosslinked; the coefficient of friction and the K factor being measured in a thrust washer apparatus as per ASTM D-3702, where the counter stationary surface in the thrust washer apparatus comprises carbon steel having a Rockwell C hardness of 18 to 22 and a 12 to 16 micro-inch surface finish.

摘要:
The disclosure concerns compositions comprising: from about 40 wt. % to about 99.5 wt. % of a polymer base resin; N from 0 wt. % to about 60 wt. % of a reinforcing filler; from 0 wt. % to about 25 wt. % of a lubricant; and from about 0.05 wt. % to about 6 wt. % of a cross-linking agent; wherein the composition is treated to induce cross-linking, wherein the combined weight percent value of all components does not exceed 100 wt % and wherein the composition shows improved tensile fatigue versus a corresponding composition without the cross-linking agent.
