- Products Overview
- The NP600 series of thermoset composites is made with various paper substrates and several different phenolic resins. These combinations yield cost-effective products with excellent thermal and electrical insulation properties, machining qualities, and outstanding performance in a wide range of applications.
- Phenolic resins are fundamentally strong and resistant to high temperatures and chemicals. They thoroughly coat the surfaces and/or impregnate the reinforcing paper, which can vary from economy and mechanical grades to electrical grades, in natural or pigmented varieties, depending on the application and desired appearance. Even at high temperatures, phenolic resins retain their chemical structure and rigidity. Hence, the NP600 series provides excellent performance, even in high-temperature refractory and foundry environments, and when exposed to acids, cleaning solutions, and lubricants in the food processing industry. The NP600 series is also ideal for low-voltage, dry electrical applications.
- These laminated thermoset composites are easier to machine than metal, with less tool wear. They do not spark when struck — a key property that enables them to be used in explosion-proof environments. In addition, parts made of phenolic-paper provide strength and insulation properties that meet or exceed those of low-end thermoplastic materials.
- Phenolic-paper composites are ideal for fabricating a variety of rigid parts, including drill entry and backing, panels, washers, terminal boards, breaker arms, high-voltage switch gear components, and intricate punched parts. Specialty phenolic-paper materials can even be used to construct X-ray-clear tables, and outdoor/indoor skateboard parks. Resin impregnated “cover” sheets are applied to some grades to improve the moisture resistance, change the laminate color, and provide special properties to the composite.
- Product Features
Engineered with a low-phenolic resin content, these economy grade laminates are typically hot-punched or machined for various low-voltage electrical applications. They are best suited for applications with dry conditions.
