1、Designation: D6440 10Standard Terminology Relating toHydrocarbon Resins1This standard is issued under the fixed designation D6440; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses i

2、ndicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 The hydrocarbon resin industry continues to evolvefrom a source of replacement products for naturally-derivedmaterials to industrial materials that have no na

3、turally-derivedcounterparts. Along with this changing character of the indus-try, various manufacturing participants have introduced termsthat have led to confusion among both manufacturers andconsumers. This terminology standard is intended to alleviatethat confusion and promote standard usage of t

Terminology2.1 Definitions:C5aliphatic resin, na resin produced by the cationicpolymerization of a low-boiling aliphatic steam-crackerfraction.DISCUSSIONThe prin

Depend

This term also covers derivatives of hydrocar-bon resins.hydrogenated resin, na resin that has been subjected tosome degree of reaction with hydrogen to decrease the levelof residual u

In the context ofhydrocarbon resins, this refers to mined
