What kind of phenolic resins resol or novolac are suitable for making phenolic foam?
i make the phenolic foam out of both of them in the same formula it works out fairly well but i am engineering it to get top performance out of the polymers.
How do you make Phenolic foam?
Phenolic foam is made by mixing a phenolic resin with a blowing agent, typically a low-boiling liquid or gas, which generates gas during the curing process. The mixture is then heated, causing the resin to polymerize and expand, forming a rigid foam structure. Catalysts and additives may be included to enhance properties such as fire resistance and thermal insulation. After curing, the foam is cut into desired shapes for various applications.
How do you change the saturation of a color?
You can change the saturation of a color by adjusting the amount of gray that is mixed with the color. A higher percentage of gray will decrease the saturation, while a lower percentage of gray will increase the saturation. You can do this using image editing software or by changing the color values manually.
What is saturation effect?
Saturation effect refers to the phenomenon where an increase in input no longer results in a proportional increase in output. In other words, when the input signal reaches a certain level, the output signal ceases to increase at the same rate. This is common in electronic devices like amplifiers and filters.
How does saturation affect the magnetic circuit?
Saturation in a magnetic circuit refers to the point at which the magnetic material can no longer be magnetized fully. Once saturation occurs, any further increase in magnetic field strength will not result in a significant increase in magnetization. This can limit the amount of magnetic flux flowing through the circuit and reduce the overall efficiency.

What is balasa foam?
Balasa foam is a type of foam material that is often used in packaging, cushioning, and insulation applications. It is known for its lightweight and buoyant properties, making it suitable for various purposes requiring cushioning or protection. Balasa foam is commonly used in the transportation and manufacturing industries.
When is an increase to oxygen saturation in tissues recommended?
An increase in oxygen saturation in tissues is recommended in situations where there is decreased perfusion or inadequate oxygen delivery, such as during hypoxia, shock, or severe infections. This can help improve tissue oxygenation and prevent damage to organs due to oxygen deprivation.
How does saturation effect RF value?
In general, as saturation increases, the RF value decreases. This is because an increase in saturation tends to increase retention of the compound on the stationary phase, resulting in a lower RF value. Conversely, lower saturation levels may allow the compound to move more freely, leading to a higher RF value.
What is saturation temperature of steam?
Saturation temperature of steam is the Temperature at whihc any addition of heat does not increase the temperature of the water but produces steam.It depends upon the pressue and for every pressure there is a saturation temperature.

Can a person increase their oxygen saturation levels?
Exercise regularly. Exercise increases blood circulation and oxygen levels. Walking, swimming and jogging are just a few exercises to help increase oxygen saturation. Lose weight and stop/quit smoking. In a medical situation, you can improve oxygen saturation by providing breathing oxygen.
