2 Laminates Key Characteristics Corrosion resistant Good insulating characteristics at low temperatures Good machinability

3 Thermoset Laminates Phenolics Epoxies Melamines Silicones Polyesters Composites

4 Laminates Process Heat and pressure applied to the top and bottom of the material. Resin Binder Reinforcing Substrate

5 Laminates Types Paper based Cotton based Glass based Synthetic fabric based

6 Phenolic Laminates Strengths High degree of resistance to deforming under load Can withstand 149°C/300°F continuously One of the hardest plastics available Cross-linked phenolics are very resistant to compressive loads

7 Phenolic Laminates Limitations Brittleness Impact resistance Moisture resistance is limited Resins darken when exposed to heat and ultra violet light

8 Phenolic Laminates Types Paper based – Grades X, XX, XXX, XP, XXP, XXXP, XPC, XXPC and XXXPC Cotton based – Grades C, CE, CYB, L, LE, LYB, LM

9 Phenolic Laminates Applications Wiring devices Switch gear Circuit breakers Insulators Gears Wear guides Pulleys Rollers

10 Epoxy Laminates Strengths Offer virtually no water absorption Good insulating and electrical properties Excellent dimensional stability Good temperature and chemical resistance

11 Epoxy Laminates Limitations Brittle Poor UV resistance Poor weathering resistance

12 Epoxy Laminates Types G-10 FR-4 G-11 FR-5

13 Epoxy Laminates Applications Electrical insulators Circuit board backing Construction Aviation/aerospace

14 Silicone Laminates Strengths Retain properties over a wide temperature range Remain flexible down to negative 16ºC/60ºF High degree of biocompatibility

15 Silicone Laminates Limitations Tensile strength low Abrasion resistance low Swell in oils, fuels and other solvents

16 Silicone Laminates Type G-7 (glass cloth reinforced silicone)

17 Silicone Laminates Applications Sealants Gaskets Medical

18 Polyester Laminates Strengths Low cost Good arc and track resistance

19 Polyester Laminates Limitations Lower abrasion resistance Brittle Great change to electrical properties in humid environments

20 Polyester Laminates Types GPO-1 GPO-2 GPO-3

21 Polyester Laminates Applications Structural profiles Soldering pallets

22 The End
