The difference between PE sheet and HDPE sheet

PE sheet has the characteristics of high toughness, good tensile and wear resistance. It is widely used in chemical industry, clothing, packaging, food and other fields. It can be filled, flame retardant, modified, embossed and ground.

HDPE sheet (low pressure and high density polyethylene) has higher rigidity, higher mechanical strength and higher melting point. Suitable for hollow products, injection products, etc., widely used in the manufacture of ice hockey wallboard. Thickness: 1-150 mm color: natural color, white, blue, yellow, grey, black, green and so on.

PE sheet has excellent resistance to most domestic and industrial chemicals. Certain types of chemicals can cause chemical corrosion, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). The polymer does not absorb moisture and has good water vapor resistance, and can be used for packaging purposes. HDPE sheet has good electrical properties, especially high dielectric strength, which makes it very suitable for wires and cables. Medium to high molecular weight grades have excellent impact resistance, even at room temperature and - 40F low temperature. The unique characteristics of various HDPE grades are the proper combination of four basic variables: density, molecular weight, molecular weight distribution and additives. Different catalysts are used to produce customized polymers with special properties. These variables are combined to produce different HDPE grades for different purposes and achieve the best balance in performance. It has good chemical stability and can resist the erosion of most acid, alkali, organic solution and hot water. Electrical insulation is good.



The melting point of HDPE sheet (high density polyethylene sheet) is about 130 C, and its relative density is 0.941~0.960. It has good heat resistance and cold resistance, good chemical stability, high rigidity and toughness, and good mechanical strength. Dielectric properties and environmental stress cracking resistance are also good. The melting temperature ranges from 220 C to 260C. For materials with larger molecule size, the melting temperature range is suggested to be between 200 and 250 C.

How to deal with the problem of fusion line?

图片
Reason analysis: From the perspective of plastics, the melting line is essentially caused by the incomplete melting of two plastic flow fronts. Solution: To eliminate or reduce the melting line, plastics must have low viscosity, high temperature, sufficient pressure and enough time to melt completely. Usually, in the case of good exhaust, accelerating the filling and feeding speed and increasing the pressure as soon as possible after the combination of two plastic flow fronts will help to solve the melting line problem.

How to solve the problem of surface depression?

图片
Basic Reasons : From the perspective of plastics, when the plastics are cooled and contracted, insufficient feeding will lead to dents on the external surface or holes in the interior of the products. Depression occurs in different locations, and the causes and solutions of the defects are also different. 1. When the depression occurs at the final cooling position of the thick-walled product or at a distance from the gate: Cause analysis: Typical surface depressions or voids at the thick wall and far away from the gate are usually due to the increase of effective viscosity and pressure loss, resulting in insufficient cavity pressure, resulting in insufficient feeding pressure. Solution: Increase the pressure of feeding and speed up the feeding rate 2. Surface depressions or cavitations occur near the gate Cause analysis: Depression occurs near gate, usually due to lack of gate freezing. There are several reasons affecting gate freezing: it may be caused by the decrease of ef...

Analysis of Common Defects in Plastic Products-Size Change

Basic Reasons: From the perspective of plastics, the reasons for the size change are as follows: The change of pressure distribution in U-shaped cavity will cause the change of size. For crystalline plastics, the change of crystallinity due to the change of cooling rate will cause the change of size. After-treatment of U products, changes in ambient temperature and humidity can also cause size changes. Next, the change of pressure distribution in the cavity and the size change are analyzed and discussed. The causes of defects will vary with the size changes. First, defect phenomenon: the overall product size is too small. Cause analysis: the plastic pressure in the cavity is too low. Solution: Increase the feeding pressure to meet the cavity pressure required by qualified products. 2. Defects: Overall product size is too large Cause analysis: the plastic pressure in the cavity is too high. Solution: Reduce the feeding pressure to achieve the cavity pressure require...
