The lid 200 or the sealing means 210 is in close contact, the heat-resistant material is elastic in nature of the material can further maximize the close contact between the container 100 and the lid 200.

The heat resistant material may be a heat resistant resin or a heat resistant rubber.

That is, the heat-resistant resin is 1 in the group consisting of phenol resin, melamine resin, silicone resin, urea resin, nylon resin, polyester resin, orientation crystallization resin, non-oriented crystallization resin, non-oriented crystallization resin, biaxially stretched PET film and polycarbonate Can be selected.

The phenol resin was first developed among plastics and is also called bakelite. Made from phenol and formaldehyde as raw materials, it is inexpensive, generally not brittle, and has good electrical insulation.

The melamine resin is a thermosetting resin obtained by reacting melamine with formaldehyde in weak alkali or weak acidity, and can be cured by acid or heat. Used in molding materials, paint materials, adhesives, textiles and paper processing agents. Also hardness. Excellent water and heat resistance.

The silicone resin refers to a polymer obtained by condensation reaction of an organic silicone intermediate. Generally silicone refers to the polymer of an organosilicon compound, and silicone oil according to the state. Silicone grease. It is called silicone resin and is rich in water repellency and electric insulation. Chemical resistance. Aging resistance and non-volatility, etc. are superior to pure organic materials.

The urea resin is made by reacting urea obtained from carbon dioxide or ammonia by dehydrating formaldehyde initial condensate and adding a pulp, a colorant, or the like. The coloring effect is good and does not interfere with alcohol.

The nylon resin is a chain polymer. Most of them have properties that can be made into fibers. Especially, they are used for the purpose of requiring heat resistance by being mixed with phenol resin or others.

The polyester film has the strongest rigidity, has excellent electrical properties, has a high elastic modulus, can be used as an extremely thin film, has high rigidity, transparency, impact resistance, and tensile strength, which is three times the tensile strength of cellophane. 10 times as much as polyethylene. In addition, there is little change depending on the temperature can be used a wide range of temperatures that can be used from -60 ℃ to 150 ℃.

The main use of the polyester is used for the purpose of utilizing transparency, strength, hardness, dimensional safety, high strength against impact and the like.

The orientation crystallization resin is oriented in a stretched PET film, transparent and greatly improved strength, good dimensional stability at high temperature. In recent years, the use of the uncrystallized microcrystalline film using the property is developed.

Non-oriented crystallization resin heats microcrystalline PET resin. When crystallized by cooling, spherical crystals grow and lose transparency, but heat resistance improves to near the crystal application temperature. That is, glass transition temperature. Heat deflection temperature. Microwave oven heating due to softening temperature. It is applied as a container 100 for oven heating. It is known as a container 100 that can withstand temperatures of about 200 ° C.

The non-oriented microcrystallized resin has a property of ensuring heat resistance, tensile strength, gas barrier properties, impact resistance, and the like.

The biaxially stretched PET resin is weak in active hydrogen and melts by adding an additive having a polar group such as an antistatic agent, a lubricant, an antifog additive, and the like, which is added to a general OPP, and the ester bond of the PET is decomposed. Since the ester bond of PET is polar, it has less surface resistivity than OPP without adding an antistatic agent.

In addition, as the heat resistant rubber, fluororubber or silicone rubber may be applied.

The fluorocarbon rubber is a hydrocarbon polymer having a high degree of fluorination. In general, all high fluorinated polymers are very stable and have very good oxidation resistance, weather resistance, flame retardancy, chemical resistance and oil resistance to many fluids. This stability is due to the higher C-F bond strength than the C-H bond.

In addition, the silicone rubber (silicone rubber) is a colorless or faint yellow elastic solid with slight fluidity even at room temperature, also called silicon rubber. The molecular weight is larger than that of silicone oil, and the molecular weight is about several hundred thousand, and some of the commercially available methyl groups -CH3 are substituted by phenyl group -C6H5 and vinyl group -CH2 = CH. It has good heat resistance and does not lose rubber elasticity.

The polycarbonate is a general term for a polymer having a carbonate ester bond -0-R-O-CO- repeatedly in the molecular main chain. Also called polycarbonate, the practical thermoplastic resin is a polycarbonate ester of bisphenol A. Transparent and excellent mechanical properties especially impact resistance. Heat resistance. Tolerance. Balanced electrical properties, non-toxic and self-extinguishing engineering plastic.

The heat-resistant material as described above is harmless to the human body, the allowable temperature that is not fused or carbonized is 150 ~ 250 ℃, if used intermittently for a short time can be used up to 350 ℃.
