Composite material reinforcement materials. Another important factor is the gross quantity of material to be produced. Large quantities can be used to justify high capital expenditures for rapid and automated manufacturing technology. Small production quantities are accommodated with lower capital expenditures but higher labour and tooling costs at a correspondingly slower rate. Many commercially produced composites use a polymer matrix material often called a resin solution. There are many different polymers available depending upon the starting raw ingredients. There are several broad categories, each with numerous variations. The most common are known as polyester, vinyl ester, epoxy, phenolic, polyimide, polyamide, polypropylene, PEEK,
Polymer capacitor aluminum oxide and tantalum pentoxide have little impact on the specific capacity due to different safety margins in oxide layers. Polymer Ta-e-caps use an oxide layer thickness that corresponds to approximately four times the rated voltage, while the polymer Al-e-caps have about twice the rated voltage. Cylindrical polymer aluminum capacitors based on the technique of wound aluminum electrolytic capacitors with liquid electrolytes. They are available only with aluminum as anode material. They are intended for larger capacitance values compared to rectangular polymer capacitors. Due to their design, they may vary in height on a given surface mounting area so that
