Abstract
A method of forming a modified thermoplastic structure for a down-hole application comprises forming a thermoplastic structure comprising at least one thermoplastic material formulated for crosslinking using an electron beam process. The thermoplastic structure is exposed to at least one electron beam to crosslink polymer chains of the thermoplastic structure. Other methods of forming a modified thermoplastic structure, and a down-hole tool are also described.
Claims22
A method of forming a modified thermoplastic structure for a down-hole application, comprising:
- forming a thermoplastic structure comprising at least one thermoplastic material comprising polymer chains that at least partially crosslink upon exposure to an electron beam;
- and
- subjecting the thermoplastic structure to an electron beam process to crosslink at least a portion of the polymer chains of the thermoplastic structure.
A method of forming a modified thermoplastic structure for a down-hole application, comprising:
- forming a thermoplastic powder comprising thermoplastic particles each comprising at least one thermoplastic material comprising polymer chains that at least partially crosslink upon exposure to an electron beam;
- crosslinking at least a portion of the polymer chains of at least a portion of the thermoplastic particles to form a modified thermoplastic powder;
- and
- forming the modified thermoplastic powder into a thermoplastic structure.
A down-hole tool comprising at least one modified thermoplastic structure comprising an electron beam irradiated material comprising at least one of polyetherketone, polyetheretherketone, polyetherketoneketone, polyetherketoneetherketoneketone, polyphenylene sulfide, polyphenylsulfone, self-reinforced polyphenylene, a polyimide, and a polyamideimide.
