Laminate manufacturing with phenolic resins and high quality neutral paper. Which has good mechanical and electrical properties and punching characteristics. The material resists low acid concentrations (except chromic and nitric), but does not withstand alkaline products. Phenolite is not attacked by common solvents such as alcohol or petroleum derivatives.
Laminate manufacturing with phenolic resins and cotton fabric with good mechanical and electrical properties. Resistant to a wide range of corrosive agents, especially those with acidic characteristics, but it does not withstand alkaline products, except for pH levels of up to 10 for a limited amount of time.
