What is the price of plastic polyethylene PE in Qilu Chemical City today?

Qilu Chemical City PE market in the morning mostly wait and see the adjustment of the new petrochemical policy, basically maintained yesterday afternoon**, 7042 tax 8200 yuan ton, 02TN26 tax 7950-8000 yuan ton, 02TN00 tax 8750-8800 yuan ton, 00TN00 tax 8400 yuan ton, 6098 tax 7850-7900 yuan ton. The listing policy of PetroChina has a certain negative impact on businesses.

There are many types of polyethylene (PE), many grades, different types and different grades of polyethylene are different, and even the same type, brand, and manufacturers are different.

1, HDPE (high-density polyethylene)**, 2015-03-30 petrochemical enterprises ex-factory ** (yuan tons):

<>2, LDPE (low-density polyethylene)**, 2015-03-30 petrochemical enterprise ex-factory ** (yuan tons):

<>3, LLDPE (linear low-density polyethylene)**, 2015-03-30 petrochemical enterprise ex-factory** (yuan tons):

PS: Plastics** fluctuate frequently, subject to real-time**.

There are many kinds of polyethylene (PE), many grades of rubber, different types of different grades of polyethylene are different, and even the same kind such as coincidence, grade, manufacturer is not the same. 1, HDPE (high-density polyethylene)**, 2015-03-30 petrochemical enterprises ex-factory ** (yuan tons): 2, LDPE (low-density polyethylene)**.

At the end of the year, Ju was witty and perfunctory.

There are many types of polyethylene, and the types and models are different, so you can choose the type and model according to the application. HDPE, LDPE, LLDPE, etc.

Its softening point is 125°--135°, and the operating temperature can reach 100°. The values of such parameters are concluded in specific cases. 100°, if it is an HDPE cup, pour a glass of water, it will not burn the cup, and it may not be deformed.

But who has been in a cup for 10 hours at 100°, it is conceivable that the cup will definitely be deformed. Of course, in terms of physical changes, I personally think that toxic substances will be released. Otherwise, compared to what can be produced with HDPE, there will be no higher PP.

PE plastic PE plastic.

Polyethylene) English name: polyethylene

Specific gravity: grams cubic centimeters Molding shrinkage: Molding temperature: 140-220 Drying conditions: --

Material properties Corrosion resistance, excellent electrical insulation (especially high-frequency insulation), can be chlorinated, irradiation modification, can be reinforced with glass fiber. The melting point, rigidity, hardness and strength of low-pressure polyethylene are high, the water absorption is small, and it has good electrical properties and radiation resistance; The flexibility, elongation, impact strength and permeability of high-pressure polyethylene are better; Ultra-high molecular weight polyethylene has high impact strength, fatigue resistance and abrasion resistance. Low-voltage polyethylene is suitable for making corrosion-resistant parts and insulating parts; High-pressure polyethylene is suitable for making films, etc.; Ultra-high molecular weight polyethylene is suitable for making shock-absorbing, wear-resistant and transmission parts.

Molding performance 1Crystalline material, small moisture absorption, do not need to be fully dried, excellent fluidity is sensitive to pressure, it is advisable to use high-pressure injection when molding, the material temperature is uniform, the filling speed is fast, and the pressure holding is sufficient. Direct gate should not be used to prevent uneven shrinkage and increased internal stress.

Pay attention to the location of the gate to prevent porosity and deformation.

2.The shrinkage range and shrinkage value are large, the directionality is obvious, and it is easy to deform and warp. The cooling rate should be slow, and the mold should be equipped with a cold material cavity and a cooling system.

3.The heating time should not be too long, otherwise decomposition and burns will occur.

4.When soft plastic parts have shallow side grooves, they can be forcibly demolded.

5.Melt rupture may occur and should not be in contact with organic solvents to prevent cracking.

The decomposition temperature of polyethylene is above 380 degrees. If it is heated together with food during cooking, the temperature will not reach its decomposition temperature.

Pure polyethylene decomposition does not produce toxic substances. However, some processing aids will be added to the production process of general polyethylene products, such as heat stabilizers, antioxidants, etc. Some of these substances decompose at very low temperatures, and some of them may have safety concerns in their own right.

Therefore, as long as it is a polyethylene container for regular food packaging, the heating temperature is not too high, and it will generally not decompose and produce toxic substances.
