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.

∙ 11y agobecause if it would be a metal handle being a conductor of heat and electricity,,,,,it would conduct heat and electricity and we may get our handa burnt or get a electric shock........so to avoid this....plastic is used as it is a insulator of both heat and eleatricity

Why do electric irons have a plastic handle?
Electric irons are made of iron, and since iron is a good conductor of electricity, if you touch it with your bare hands you would get shocked. Plastic doesn't conduct electricity and is one of the best insulators, so it would be safe to use plastic handles while ironing. Even if the ironing machine isn't electric, the machine is bound to get heated, and if you touch it to use it, you would burn your hand, so no matter the type of ironing machines, you always need a plastic handle.

Why the plastic handle used in the pressure cooker doesn't melt?
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
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).

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.
