| description | The invention relates to polyvinylidene fluoride (PVDF) copolymer compositions that have improved crosslinking efficiency and performance. The PVDF copolymer contains a high level (>14 and preferably greater than 16 wt %) of a fluorinated comonomer, and has a high molecular weight as measured by the melt viscosity at 230° C. and 100 sec−1 of 18 to 40 kpoise. The composition can be effectively cross-linked with a low level radiation (high cross-linking efficiency). The cross-linked composition is useful in high-temperature applications, such as automotive wire and cable, and heat shrink tubing. |
