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 substrate Australia CSIRO. Countries like Bulgaria have issued a combination of paper and polymer as the 200 Lev banknote. Polymer substrate Polymers and plastics known as polymer substrates are used for banknotes and other everyday products. The banknote is more durable than paper, won't become soaked in liquids and is harder to counterfeit, though not impossible. Countries whose whole banknote production is in polymer are: Australia, Romania, Vietnam and New Zealand. Other countries that have partial polymer and paper issue include Papua New Guinea, Samoa, Solomon Islands, Mexico, Zambia, Brunei, Malaysia, Singapore, Nigeria, Chile, England and Nepal. The material is also
