Foam Polyethylene Made of Recycled Polyethylene

IOP Conference Series: Materials Science and Engineering, 2021
Abstract The paper deals with the main principles of foam polyethylene production by the addition of recycled polyethylene and a modifier in the initial mixture. Obtaining of the modified foam polyethylene will accomplish two important tasks: solve the environmental problem of recycling polyethylene waste and reduce the cost of the ...

Velcrand Functionalized Polyethylene [PDF]

Molecules, 2019
Velcrands are a specific class of cavitands whose complementary surfaces induce self-dimerization. The insertion of a velcrand as physical cross-linking unit into a polymer is reported. To this purpose, the velcrand was functionalized at the lower rim with an isocyanate group.

The Optical Behavior of Polyethylene Spherulites [PDF]

, 1967
Polyethylene was crytallized from the molten film under temperature gradient. As a result, the optically positive spherulites were observed, though only the negative spherulites had been observed previOusly in polyethylene.

FDM preparation of bio-compatible UHMWPE polymer for artificial implant [PDF]

, 2016
Due to its properties of high wear, creep resistance, high stiffness and strength, Ultra-High Molecular Weight Polyethylene (UHMWPE) was developed to eliminate most metallic wear in artificial implant, which conventionally found in stainless steel ...

Catalytic Hydroxylation of Polyethylenes [PDF]

ACS Central Science, 2017
Polyolefins account for 60% of global plastic consumption, but many potential applications of polyolefins require that their properties, such as compatibility with polar polymers, adhesion, gas permeability, and surface wetting, be improved. A strategy to overcome these deficiencies would involve the introduction of polar functionalities onto the ...

Microstructural contributions of different polyolefins to the deformation mechanisms of their binary blends [PDF]

, 2020
The mixing of polymers, even structurally similar polyolefins, inevitably leads to blend systems with a phase-separated morphology. Fundamentally understanding the changes in mechanical properties and occurring deformation mechanisms of these immiscible ...

Biodiesel permeability in polyethylene [PDF]

Polymer Testing, 2012
This paper reports solubility, diffusivity and permeability data for soy and rapeseed methyl esters in polyethylene together with comparisons with methyl oleate and linoleate. The solubility was estimated on the order of 5% in weight at room temperature and increased up to more than 10% at 75°C.

Hybrid materials based on polyethylene and MCM-41 microparticles functionalized with silanes: catalytic aspects of in situ polymerization, crystalline features and mechanical properties [PDF]

, 2016
New nanocomposites based on polyethylene have been prepared by in situ polymerization of ethylene in presence of mesoporous MCM-41. The polymerization reactions were performed using a zirconocene catalyst either under homogenous conditions or supported

Laser-assisted photothermal imprinting of nanocomposite [PDF]

, 2004
We report on a laser-assisted photothermal imprinting method for directly patterning carbon nanofiber-reinforced polyethylene nanocomposite. A single laser pulse from a solid state Nd:YAG laser (10 ns pulse, 532 nm and 355 nm wavelengths) is used to ...
