[ Phenolics, Paper Reinforced ]

Phenolics, Paper Reinforced

Phenolics are the result of polymerization between layers of paper, canvas, linen, or glass cloth impregnated with synthetic thermosetting resins. These industrial laminates are a popular alternative to acrylic, because of its high resistance to flexing.

The base material (paper, linen cotton, cotton canvas, or glass cloth) and resin combination used is dependent upon the intended application of the finished product. Physical strength, resiliency, ease and versatility of fabrication, and excellent electrical properties make phenolics useful as support components in a wide range of mechanical and electrical applications.

X/XX/XXX Paper Base Phenolic: The "X" designations generally distinguish manufacturing processes which result in different levels of electrical properties (i.e., dielectric strengths). Paper-based phenolics with enhanced mechanical and electrical properties are available in a variety of sheet, rod, and tube sizes.

Certifies to NEMA X per MIL-I-24768/12 PBM; NEMA XX per MIL-I-24768/11 PBG; NEMA XXX per MIL-I-24768/10 PBE.
