Webmaterials can be sub-segmented according to their composition, and include paper, composite, FR-4, high T. g FR-4, and specialty products (polytetrafluoroethylene (PTFE) and high-performance materials). Paper and composite laminates represent 17.1 percent of the global laminate market in value (Figure 2-2). WebBakelite. Bakelite is one of the oldest polymers that was synthesized by man. It is a thermosetting polymer and has high strength and retains its shape after moulding. It is one of the first polymer/plastic created in a laboratory. The polymer is formed by condensation of formaldehyde with phenol. Its chemical formula is (C 6 H 6 O·CH 2 O) n.
