PTFE COMPOSITIONS CONTAINING ANISOTROPIC MELT-FORMING POLYMERS |
摘要 |
Compositions containing a polymer of PTFE and a polymer capable of exhibiting an anisotropic melt characterized in that the compositions contain between 0.05 and 99.5% of PTFE and 0.5 to 99.95% by weight of the polymer capable of forming an anisotropic melt. The presence of a minor amount of the anisotropic melt-forming polymer, that is, from 0.5 to 50% by weight of the composition enables the processability of PTFE to be improved, even to the extent of providing an injection mouldable PTFE composition. Compositions containing 20 to 50% by weight of PTFE confer benefits on anisotropic melt-forming polymers, such as lubricity and greater versatility in fabrication operations. Concentration of 0.05 to 5.0% by weight of PTFE are particularly suitable for modifying the viscosity characteristics of the low melt viscosity anisotropic melt-forming polymers so that such anisotropic melt polymers are less subject to problems such as flashing and jetting during moulding. |
