What kind of material is PP material resistant to high temperatures?

PP in plastic refers to polypropylene, which is resistant to boiling water temperature, melting point 165, softened at about 155, and the use temperature range is -30 140.

PP plastic tableware has good heat resistance and can be used for microwave heating, but it is not suitable for use in frozen packaging. In addition, foods with high acid and oil content generally do not react chemically with plastic tableware.

Polypropylene is widely used in the production of clothing, blankets and other fiber products, medical equipment, automobiles, bicycles, parts, transportation pipelines, chemical containers, etc., and is also used in food and pharmaceutical packaging.

PP is an engineering plastic. PP material is not resistant to high temperatures, but it is heat resistant.

PP is the abbreviation of polypropylene, the Chinese name is polypropylene, commonly known as 100 fold glue. PP (polypropylene) is prepared by catalytic polymerization of propylene monomer using Ziegler-Natta catalyst, and is a crystalline isometric polymer with neat molecular links.

PP (polypropylene) can be divided into isometric PP (polypropylene) and random PP (polypropylene) according to its crystallinity, and isometric polypropylene is a highly crystalline thermoplastic resin with a crystallinity of more than 95% and a molecular weight between 8-150,000;

Thermal performance, as the name suggests, is the heat resistance of PP material. We say that PP material can be melted at high temperatures and has fluidity, but this high temperature is generally unattainable. Because the PP material has good heat resistance, the products made of PP material will not be deformed in the slightest after boiling water.

Hope, thank you.

High temperature resistance.

PP material is resistant to high temperature and non-toxic, and is often used in the production of kitchen utensils, bottles, cups, lunch boxes, etc. Normal atmospheric pressure.

The boiling point of water is 100, and the heat deflection temperature of PP products is about 121, so it is a very safe plastic.

PP material. It is polypropylene, which is a non-toxic, odorless, tasteless milky white highly crystalline polymer with a density of only 0 90--"0.At 91g cm3, it is one of the lightest varieties of all plastics at present.

It is particularly stable to water, with an absorption rate of only 001%, with a molecular weight of about 80,000 to 150,000. The formability is good, but due to the large shrinkage rate (1% Thick-walled products are easy to dent, and it is difficult to meet the requirements for some parts with high dimensional accuracy, and the surface gloss of the products is good.

Polypropylene, a kind of plastic, it is a high-density, side-chain-free, high-crystalline linear polymer with excellent comprehensive properties. Common products: basins, barrels, furniture, films, woven bags, bottle caps, car bumpers, etc.

PP plastic, chemical name: polypropylene, English name: polypropylene (abbreviated as PP) specific gravity: grams cubic centimeters.

Molding shrinkage: Molding temperature: 160-220 pp is a crystalline polymer.

The comprehensive performance of PP is better than that of PE material. PP products are lightweight, have good toughness and good chemical resistance.

Disadvantages of PP: low dimensional accuracy, insufficient rigidity, and weather resistance.

Poor, it has the phenomenon of post-shrinkage, after demolding, it is easy to age, brittle, and easy to deform. In daily life, the commonly used fresh-keeping box is made of PP material. Made.

Ordinary PP material has a high temperature resistance of about 100 degrees; Fiber PP can withstand high temperature of 120-135 degrees

PP material can withstand high temperature, under normal circumstances, its maximum heating temperature is 120-150, generally speaking, the temperature of boiling water is 100, PP material water cup is much higher than the temperature of boiling water, so when using PP material, you don't have to worry that it can not withstand high temperature, and dare not use PP material items.

PP material is mainly familiar with plastic material, in the past, people did not have a complete understanding of plastic, there was a misunderstanding, that the plastic cup can only be filled with cold water or warm water, can not be filled with boiling water, filled with boiling water will melt off the plastic, in fact, this is wrong information, people for the quality of the rotten PP material cup and the heating temperature should be resistant to the skin should be confident.

Characteristics and uses of PP plastic.

PP plastic, also known as polypropylene, is another excellent resin variety developed after nylon. It has high impact resistance, strong mechanical properties, and resistance to a variety of organic solvents and acid and alkali corrosion. It has a wide range of applications in the industry and is one of the common polymer materials.

PP plastic features: ultra-high hardness, high rigidity, scratch resistance, large flexural modulus.

PP plastic can be used for electric kettles, coffee pots, rice cooker lids, coffee machines, heaters, electric irons, hair dryers, dishwashers, microwave ovens and other small household appliances and electrical parts, and has a wide range of uses.

High temperature resistance. The PP water cup can withstand high temperatures, under normal circumstances, its maximum heating temperature is 120-150, the embrittlement temperature is -35, generally speaking, the temperature of boiling water is 100, and the heating temperature of the PP material water cup is much higher than the temperature of boiling water, so when using PP material, you don't have to worry that it can't withstand high temperatures, and you don't dare to fill the PP cup with hot water.

PP material is mainly familiar with plastic material, in the past, people did not have a complete understanding of plastic, there is a misunderstanding, that the plastic cup can only be filled with cold water or warm water, can not be filled with boiling water, filled with boiling water will melt off the plastic, in fact, this is wrong information, people should have confidence in the quality and heating temperature of PP material cup.

Because many of the daily necessities around us are made of PP materials, such as electric kettles, rice cookers, hair dryers, plastic lunch boxes, disposable water cups, hot water cups, etc., which are made of PP materials, so you will have questions, that is, is PP material resistant to high temperature? Because these items made of PP materials seem to endure high temperatures, such as when you drink water, the temperature of the water is relatively high, the temperature is higher when eating, and whether it will affect when cooking, etc., these are all within the scope of your consideration, so it is normal for you to have such considerations.

Is PP material resistant to high temperatures?

Generally speaking, PP material refers to polypropylene, polypropylene is a thermoplastic resin material polymerized from propylene, usually translucent, without any odor and toxicity, and its melting point is about 167. From this point of view, PP material is still relatively resistant to high temperatures, and the relatively high temperature here is compared with the temperature of water and rice, but you can safely use water cups or lunch boxes made of PP materials to eat.

Although PP material has the characteristics of high temperature resistance and corrosion resistance, and will not change for many years in the ground, its disadvantages are that it is not resistant to low temperatures and has poor impact force. We are familiar with food plastic belts like this, you gently pull with your hands, the plastic bag will be broken, so be careful when using some items made of particularly soft PP material not to be broken.

PP material will deform at a temperature of about 100, but keep in mind that it is only deformed, it will not melt, it will melt at about 167, and you don't need to worry about whether you will eat items containing polypropylene in food, and you need to be concerned about not burning your hands. Although the PP material will be deformed at 100, as long as the external impact force is not particularly large, it can still maintain the prototype.

Because of the excellent characteristics of PP material, as long as the ethylene content increases in terms of hardness, its hardness will increase relatively, the stability is good, the heat resistance type, the material is light, and the dielectric properties and high-frequency insulation under specific conditions are also excellent, and odorless and non-toxic, so this material is often used in the industry to produce parts.

It has been reported that PP materials are not suitable for use in high-temperature conditions, which is incorrect, and PP materials are not toxic in themselves, so Everbright consumers can use them under high-temperature conditions with confidence. However, some unqualified products will add some toxic additives to the PP material, and these toxic additives are not resistant to high temperature and harmful to human health, so it is recommended to go to a regular store to buy PP material items to ensure your health.
