Plastics are subidivided into two types thermoplastic and thermosetting. The thermoplastics can be softened by heat and hardened again by subsequent cooling. This process is reversible and can be repeated many times. By contrast, the thermosetting resins are first softened and melted and, at subsequent heating to a definite temperature, they are irreversibly hardened, becoming insoluble [53]. [Pg.105]

Chapter 22 didn t give you a very satisfying definition of resins. But its useful here to talk about two classes of polymers called resins thermosets and engineering thermoplastics. [Pg.359]

Premix ( gunk ) n. A term originally apphed to mixtures of polyester resin with sisal or glass-fiber reinforcement and fillers, usually prepared by molders shortly before use. The ASTM definition (D 883) specifies that the premix should not be in web or filamentous form. The term premix is now often used by molding compounds of any thermosetting resin mixed with fillers, reinforcements, and catalysts. Strong AB (2000) Plastics materials and processing.

The cationic polymerization of cardanol under acidic conditions has been referred to earlier [170,171], NMR studies [16] indicated a carbonium ion initiated mechanism for oligomerization. PCP was found to be highly reactive with aldehydes, amines, and isocyates. Highly insoluble and infusible thermoset products could be obtained. Hexamine-cured PCP showed much superior thermal stability (Fig. 12) at temperatures above 500°C to that of the unmodified cardanol-formaldehyde resins. However, it was definitely inferior to phenolic resins at all temperatures. The difference in thermal stability between phenolic and PCP resins could be understood from the presence of the libile hydrocarbon segment in PCP. [Pg.427]

Syntactic foams are obtained by mixing hollow micro- or macro-balloons, generally made of glass but sometimes of polymer, directly with a liquid resin, generally a thermoset. Some extend this definition to all composites with a foamed core. [Pg.809]
