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.
Because the plastic handle act as a thermal insulator, to avoid burns on your skin.
Sheets of plastic are often covered with layers of paper to protect them from scratches, dust, and contaminants during manufacturing and transportation. The paper layer also helps prevent static buildup, which can attract dirt and debris. Additionally, the paper can provide a surface for labeling or branding, making it easier to handle and identify the product. Finally, the paper can enhance the aesthetic appeal of the plastic sheets before they are used in final applications.
Handle of electrical ions are made up of plastic or bakelite because plastic are poor conductor of both heat and electricity so it is made up of plastic or Bakelite
Wooden or plastic handles are used on appliances like electric irons for safety reasons. These materials are non-conductive and help prevent electric shocks to the user. They also provide insulation from the heat generated by the appliance, making it more comfortable to hold during use.
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.
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

While I can't create drawings, I can describe a pressure cooker for you. A typical pressure cooker features a sturdy pot with a tight-fitting lid that has a pressure release valve. The exterior is usually made of stainless steel or aluminum, and it often includes a handle for easy lifting. Inside, there may be a metal rack to keep food elevated above the liquid, ensuring even cooking under pressure.
A pressure cooker may leak from the back handle due to a few common reasons: a faulty or damaged gasket that fails to create a proper seal, excessive pressure buildup caused by a malfunctioning pressure release valve, or food particles obstructing the vent. Additionally, if the handle is not securely attached, it can lead to gaps where steam escapes. Regular maintenance and ensuring all components are in good condition can help prevent this issue.
The handle of a pressure cooker is made from ebonite, a type of hard rubber, because it has excellent insulating properties that prevent heat transfer. Ebonite can withstand high temperatures and does not conduct heat well, ensuring that users can handle the cooker safely without risk of burns. This thermal insulation is crucial in maintaining safety and comfort while cooking under high-pressure conditions, where the surrounding metal can become extremely hot. By using ebonite, manufacturers ensure that the handle remains cool to the touch, enhancing user safety and usability.
Yes, can cooker handles can typically be recycled, but it depends on the material they are made from. If the handle is made of metal, it can usually be recycled with other metals. However, if it’s made of plastic or composite materials, check local recycling guidelines, as not all facilities accept these materials. Always ensure that the handle is clean and free from food residue before recycling.
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).
The handle is made out of plastic.
AnswerTry to put pressure under the head of the screw as you try to turn it out.

Syphon glad which is plastic has probably worn so you need to flush the handle a few times to get the flush.
