Scope
Scope: This document specifies the classification, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of phenol-formaldehyde resins. This document applies to thermoplastic phenol-formaldehyde resins used for curing epoxy resins, which are synthesized and produced primarily from phenol and formaldehyde as raw materials. Main technical content: Phenol-formaldehyde resin products are divided into three models according to their softening point, as shown in Table 1. Table 1 Phenol-formaldehyde resin product models Softening point/℃ Model [60, 80] PR-70 (80, 100) PR-90 [100, 120] PR-110 Note: ( ) indicates no end point, [ ] indicates an end point, and the same applies to subsequent items.
