Polyethylene has wide acceptance due its high chemical resistance, non-toxicity, excellent electrical properties and weight lightness; while polypropylene has high compressive and tensile strength, excellent dielectric properties and …
Environmental toxicity and biotoxicity of polyethylene. Regardless of where the polyethylene waste comes from, its accumulation in the environment is bound to cause serious problems. Estimates indicate that about 79% of polyethylene waste is sent to landfills ( Canopoli et al., 2018, Ritchie and Roser, 2018 ).
This article explains the history, from 1600 BC to 2008, of materials that are today termed 'plastics'. It includes production volumes and current consumption patterns of five main commodity plastics: polypropylene, polyethylene, polyvinyl chloride, polystyrene and polyethylene terephthalate. The use of additives to modify the properties of these …
Polypropylene (PP) and Polyethylene (PE) was heated at 110 °C until melted and mix with thermoplastic starch until homogeny using Raw mill. The mixture was then chopped into smaller size in the crusher and then process to …
The barrel is made of polypropylene, and the plunger is made of polyethylene.
Polyethylene (PE) microplastics are emerging pollutants that pose a significant threat to the environment and human health. However, little is known about the effects of PEs on soil‒plant interactions, especially in heavy metal (HM)-contaminated soil.
Polypropylene (PP) and HDPE (High-Density Polyethylene) are both commodity thermoplastics. Polyethylene, the basic building block of HDPE, is the highest production volume of plastic in the …
Polyethylene bags are semi-transparent, which is great for limiting light entry when storing items that are sensitive to light. They have low static charge, ideal for electronic components, and has higher resistance to rips and tears compared to polypropylene. Polypropylene bags have crystal clear transparency, which is great if …
Polyethylene and its variants are the most commonly used commodity plastics. Polyethylene is typically used for plastic bags, food/drink containers, and medical applications like knee joints. Polyethylene's chemical structure consists of repeated monomers made from carbon and hydrogen atoms.
A comparison of polypropylene and polyethylene, and the properties that make both a popular choice for customers.

The main differences with polyethylene are that polypropylene is lighter and more resistant to high temperatures, abrasive agents and chemical solvents. It is also more resistant to breakage, however, it is less flexible than polyethylene. Another major advantage is that it is easy to colour and mould. For all these reasons, polypropylene …
Polyethylene is generally less expensive, and low-density polyethylene can offer significant savings for high-volume shipping due to its lower weight. The lightweight nature of polypropylene packaging also …
Polyethylene is the most popular and commonly used plastic in the world, used in shopping bags, toys and shampoo bottles. There are over 100 million tonnes of the material's resins produced annually, which accounts for 34% of the plastics market. Following on from our blog post about the advantages and disadvantages of …
This work provides evidence that ultra-stable Y zeolite (USY) and HZSM-5 zeolites were active as catalysts for the pyrolysis of urban plastic wastes, decreasing its degradation temperature. When HZSM-5 was used as the catalyst, at 450 °C and 30 min, an increase in the solid fraction and a reduction in the liquid fraction were observed. On …
Recycling of waste plastics has become vital due to the threat to the environment the huge piles of those wastes represent, with research revealing High-Density Polyethylene (HDPEs) as the most dominant waste plastics. Because of their dominance and significant environmental impact, this paper reports the economic potential of …
Polypropylene, a complex plastic, is generally considered safe for humans. It's FDA-approved for food contact and is often used for containers like those that hold yogurt and butter products.
Polypropylene (PP) and polyethylene (PE) being most common, widely available and cheapest thermoplastic, if made conductive, can be revolutionary in the field of engineering thermoplastics.
To understand the process of plastic degradation in an intertidal salt marsh habitat, strips (15.2 cm × 2.5 cm) of high-density polyethylene, polypropylene, and extruded polystyrene were field-deployed in June 2014 and monitored for biological succession, weight, surface area, ultraviolet (UV) transmittance, and fragmentation.

Plastic materials have increasingly been used in the fabrication of different types of concrete admixtures and mortar constituents. These plastic materials take the form of fillers or shredded fibres derived from polypropylene and polyethylene terephthalate.
Polypropylene is located between low-density polyethylene (LDPE) and high-density polyethylene (HDPE) on the crystallinity level. It is flexible and tough, especially when it is copolymerized with ethylene. This copolymerization allows this plastic to be used as an engineering plastic that is in a number of different products and uses.
Reinforced Fabrics: Vinyl, Polyethylene and Polypropylene and When to Use Each. Industrial fabrics are designed to offer strength and durability. High-wear situations, exposure to the elements and military applications require reinforced fabrics. Often, these fabrics may be laminated or coated in vinyl to be more resistant to punctures or tears.
The barrel is made of polypropylene, and the plunger is made of polyethylene.
Generally speaking, the chemical resistance of polypropylene and polyethylene is considered superior to that of met-als. They are unaffected by most inorganic acids, alkalis, and aqueous solutions which rapidly corrode metals, although some concentrated acids and oxidizing agents can attack them, especially at elevated temperatures.
