The polymer material. Both occurred in nature (Natural polymer) and polymer synthesis (Synthetic polymer) Examples of natural polymers include cellulose, starch, protein, nucleic acid, and natural rubber. The synthetic polymer fibers such as plastic foam and adhesive polymer, the two species are involved more in their daily lives. We must take advantage of the polymer. And polymer properties, each with different acts or to use a different. The polymer material used to produce insulation is a copolymer of styrene, a polyethylene thermoplastic melt into a liquid. The temperature will be in the solid state. But will melt when heated and hardens when cooled. Poly Styrene solid pure colorless transparent but can be made into different colors and resilient limited by the type Extruded polystyrene (XPS) is a trade name used is Styrofoam is kind of the air in the channel. Empty the foam has low thermal conductivity. Used in construction And used as insulation in buildings.
