Polymer aging refers to the deterioration of polymer properties over time, which can affect their performance and lifespan. This aging can be caused by various factors including oxidative degradation, UV exposure, thermal degradation, mechanical stress, and chemical exposure. Oxidative degradation happens when oxygen in the air reacts with the polymer chains, leading to a breakdown of the polymer structure. UV exposure causes polymer chains to break due to the energy absorbed from UV radiation, leading to discoloration and embrittlement. Thermal degradation occurs when polymers are exposed to high temperatures that exceed their thermal stability, leading to a breakdown of the molecular structure. Mechanical stress, including repeated stretching or compression, can cause physical wear and tear, leading to cracks and eventually breakage of polymer chains. Lastly, exposure to harsh chemicals can attack and break down polymer chains, impacting the material's integrity. Preventing polymer aging involves minimizing exposure to these degrading conditions and often involves stabilizers and UV inhibitors to enhance polymer durability.
Anderson windows are made from a material called Fibrex, a composite that is a blend of wood fiber and thermoplastic polymer (a vinyl compound). Essentially, while this mix includes vinyl, Anderson windows are not purely PVC or vinyl but a more complex, durable material. Fibrex is designed to offer the strength and rigidity of wood with the low maintenance and resistance to decay and rot of vinyl. This makes Anderson windows more environmentally friendly and energy-efficient, as Fibrex material uses 40% reclaimed wood fiber by weight. Hence, while containing vinyl, Anderson windows transcend the typical classification of being just PVC or vinyl, providing a unique, high-performance alternative.

Resin, whether natural or synthetic, is not inherently immune to lightning. To understand this, it's important to consider both the electrical properties of resin and the mechanisms through which lightning interacts with materials. Generally, resins are poor conductors of electricity, which means they do not readily allow electrical currents to pass through them. However, when struck by lightning, which carries an extremely high voltage, the resin can still be damaged. The intense heat generated during a lightning strike can cause the resin to melt or even catch fire. Moreover, if the resin contains conductive fillers or is part of a composite material that includes metal components, it may conduct electricity more readily, increasing the risk of damage. In practical applications, such as in the construction of aircraft or wind turbine blades, where resins are often used, additional measures like incorporating lightning protection systems are necessary to mitigate the risks associated with lightning strikes.
