there are two types of Plastics. the Thermoset and the Thermoplast. these Plastics all Melt, but @ different temperatures. the Thermoplast melts easily and can be recycled, while the thermoset has a property that makes it difficult to melt @ the temperature of the cooker that is being heated.this therefore explains why the Plastice does not melt because its thermoset Plastic and It has a higher temperature

The plastic handle on a pressure cooker is made from a heat-resistant material, such as thermoset plastics like phenolics or reinforced nylon. These materials have high melting points and can withstand the temperatures typically reached during pressure cooking without melting. Additionally, the handle is positioned away from direct heat sources within the cooker to minimize the risk of melting.

What is an amount of pressure an object can handle without changing?
The amount of pressure an object can handle without changing is called its elastic limit. Beyond this point, the object will undergo permanent deformation or break.
Why is the handle of an electric iron made up of plastic or wooden material?
The handle of an electric iron is made of plastic or wood because these materials are poor conductors of heat, which helps prevent the handle from becoming too hot to touch during use. This ensures user safety and comfort while operating the iron.
What is the handle of the magnifying glass made out of?
The handle of a magnifying glass is typically made of plastic, metal, or wood. These materials are chosen for their durability, comfort, and aesthetic appeal.
What is the difference between an electric cooker cable and a bulb cable?
An electric cooker cable is designed to handle higher power loads and is typically thicker and more robust compared to a bulb cable which is thinner and designed for lower power applications like lighting. Additionally, an electric cooker cable may have different connectors and insulation ratings as it is meant for higher temperature environments.
Why does a metal spoon handle gets hot in soup but a plastic spoon handle does not?
Metal is a good conductor of heat, so when it's placed in hot soup, the heat from the soup quickly transfers to the metal spoon handle, making it feel hot. Plastic, on the other hand, is a poor conductor of heat, so heat doesn't transfer as quickly to the plastic spoon handle, keeping it cooler to the touch.
Why is the handle of the pressure cooker covered with thick plastic?
It is so because the handle is of the metal and metal are good conductors of the heat. so to escape from the heat while catching the handle hard plastic is used.

What is 15 pounds pressure in autoclave?
Steam autoclave's work at 30 to 35 PSI, the previous answer of 15 PSI is for a pressure cooker. A pressure cooker cannot be used as an autoclave, the temperature is not high enough to cause sterilization. Anything less than 121C / 250F (30 PSI) is incapable of killing microorganisms. Also the pressure vesal of a pressure cooker cannot handle the added pressure needed to sterilize, IE: adding weight to the release valve will just cause the cooker to explode (so don't try it).
Is the handle made out of plastic or glass?
The handle is made out of plastic.
How do you remove the screw that holds the plastic handle for a shower if it doesn't turn?
AnswerTry to put pressure under the head of the screw as you try to turn it out.
Why saucepans have plastic handle?
Because the plastic handle act as a thermal insulator, to avoid burns on your skin.
Why is a plastic handle the best thing?
Because the plastic handle act as a thermal insulator, to avoid burns on your skin.
What could be the problem for a tolet to have not enough pressure to flush?
Syphon glad which is plastic has probably worn so you need to flush the handle a few times to get the flush.
How do you cook tamales in a pressure cooker?
Pressure cookers can be dangerous. You have to make sure the seal (gasket) is in good condition and that the valve is working if you are using one you got secondhand. There should be instruction manuals for many pressure cookers on the Internet.Basically pressure cookers build up heat because they are sealed so well. They cook food much faster than a normal pot - You can cook a roast in about 20 minutes. They are also used frequently in canning veggies and other nonacidic foods.There is a pressure gauge on the top. You have to let the pressure go down before opening the pot! Please don't use one until you know what you are doing or your least problem will be a huge mess.First inspect the pressure cooker tharoughly and ensure that there are no damages especially to the gasket and see that it is clean.Next, you also need to ensure that the vent pipe is open and clear for pressure cooker with weighted pressure regulator. Check recipe for specific cooking method and cooking time. If your recipe requires a rack place it to the bottom of the cooker.Add a 1/2 cup water to pot if you're using a cooker that has a weighted system. Add 1 cup for pressure cooker that uses valve system. This should be sufficient for 20 minutes of cooking time.Place the food on rack.With the weighted system cooker remove the regulator then close and secure the lid. The cover handle should be parallel to the body handle. Place the cooker on heat.Once the steam begins to exit the vent pipe, replace the regulator. The weight on top the lid will begin to rock once the cooker reaches cooking pressure.The valve system cooker has markings on the cooker that indicate the pressure levels. Once the indicator is at 15 PSI the cooker is at the standard cooking pressure.Now, lower the heat once the cooker is at the cooking pressure in order to maintain the pressure. Comeback and chek and adjust the heat setting periodically.Use the timer to time the recipe.Once the required time is passed, you can turn off the heat.Next, you need to release the pressure inside by allowing it to reduce on its own.Once the pressure is released the lid can be opened after the removing the regulator.Hope this helps.
