Specification for industrial rigid laminated sheets based on thermosetting resins for electrical purposes―Definitions,designations and general requirements
GB/T 18381-2001 Specification for industrial rigid laminated sheets based on thermosetting resins for electrical purposes - Definitions, designations and general requirements
1 Scope
This standard specifies the definitions, designations and general requirements of industrial rigid laminated sheets based on thermosetting resins for electrical purposes.
This standard is applicable to industrial laminated sheets. These laminated sheets are made with any of the following resins as the binder: phenolic, unsaturated polyester, polyimide, epoxy (epoxide), melamine and silicone. This part of the standard also includes general requirements to be fulfilled by industrial laminated sheets. The following reinforcements may be used either singly or in combination: asbestos paper, asbestos cloth, cellulosic paper, cotton cloth, glass cloth, glass roving, glass mat, polyester cloth and wood veneers.
2 Definitions
For the purposes of this standard, the following definitions apply.
2.1
laminated sheets
industrial laminated sheets based on thermosetting resins consisting of superimposed layers of paper, cloth, felt (mat) or wood veneers that have been substantially impregnated with thermosetting or curable resin and bonded together under pressure, with or without heat, to form a single piece, with other constituents, for example colouring matter, capable of being incorporated.
2.2
phenolic resin
generic term for a class of resins made by the polycondensation of phenol, its homologues and/or derivatives, with formaldehyde
2.3
polyester resin (unsaturated)
polymer consisting of chains with repeated structural units of the ester type with double-bond polymerization, which permits subsequent cross-linking
2.4
eposide (epoxy) resin
synthetic resin containing epoxide groups, which is formulated to enable cross-linking
