Because LDPE is an abbreviation of Low Density Poly Ethylene, whereas HDPE stands for High Density Poly Ethylene. This means LDPE is less efficiently packed together than HDPE, due to the larger amount of branching found in LDPE, leading to a weaker material.
yes. it is amorphous.
A is greater than B (A>B). C is less than D (C<D). But what about "less than or equal"?
Bamboo flooring is typically less exspensive than hardwood flooring. You can get laminate wood flooring for less cost than bamboo.
There are 1.609344 kilometres in one mile. This is less than 2 kilometres.
Easy, put a fruit in water and if it floats it is less dense than water.
20dm (decimetres) in equal to 2000mm (millimetres), so no 2000000mm is not less than 20dm.
LDPE is softest, HDPE is harder, PMMA is much harder than HDPE
Usually with a 'rubberizing' additive that contains LLDPE (Linear low density polyethylene) More branches and better bonding, less amorphous. Greater tensile and impact strength than LDPE or HDPE.
LDPE (Low-Density Polyethylene) has more branching in its molecular structure than HDPE (High-Density Polyethylene), giving it a lower density and flexibility. HDPE is more rigid and has a higher tensile strength compared to LDPE. LDPE is commonly used for packaging and bags, while HDPE is often used for bottles and containers.
HDPE has higher density therefore it has greater tensile strength
LDPE is softer, more flexible and melts at lower temperatures than HDPE. LDPE is used for things like sandwich bags. HDPE is harder, has a higher chemical resistance and can withstand higher temperatures. (120 Degrees Celsius for short periods and 110 Degrees Celsius continuously) It is used for things like Plastic bins.
Technically, adequately made LDPE and HDPE bags/containers are safe for food storage and consumption. Recycled materials and unsafe additives/colors, etc. must not be added.For instance, LDPE bags are more transparent in nature than HDPE, so it ideal for clear zip-lock sandwich bags. HDPE is tougher and opaquer (UV protection of sensitive foods), so used for milk bottles. Consider factors like barrier, toughness, seal ability before making your purchase.
With water. PETE has a greater density than water where HDPE has a density less than water
Sometimes
Polyethylene is a lightweight thermoplastic made from hydrocarbons. Low-density polyethylene (LDPE) is the most widely used plastic. It is relatively inexpensive, flexible, strong, and chemical-resistant, and can be molded molded into bottles, food packaging, and plastic toys. High-density polyethylene (HDPE) is stronger than LDPE and is made into products such as grocery bags, car parts, packaging, and piping.
I don't know. Is less than 50 diopter
•Biominerals tend to: -Be finely crystalline (less crystalline than geominerals) -Have more organics -Be stronger than geominerals -Be easier to form than geominerals (aragonite vs. calcite)
Crystalline precipitates have less surface area than the colloidal precipitates, therefore they are more pure. Additionally, crystalline precipitates, because they are larger, are more easily separated from the surrounding solution.
