ketones such as acetone and methyl ethyl ketone; and alcohols such as methanol and isopropanol. There is an upper temperature limit of solubility in water for the high molecular weight poly(ethylene oxide)s; this varies with concentration and molecular weight but is usually between 90 and 100??
BREATHABLE LAMINATE AND METHOD OF MAKING SAME resin further can be, for example, a low density polyethylene (LDPE), linear low density polyethylene (LLDPE), 5 polypropylene (PP), ethylene vinyl acetate (EVA), ethylene methacrylate (EMA), or any coextrusion or blend thereof. A... CN Mou -...
Active plastic films can be developed via the inclusion of active agents within BCD in the form of a powder, which is subsequently incorporated into the polymer matrix. For this purpose, the polyethylene (PE) polymer matrix comprises an excellent candidate given its extensive use in the food pac...
Ezatollah Joudaki, in Journal of Energy Chemistry, 2020 Graphical abstract Polyethylene oxide (PEO) as an advanced polymer in the fabrication of CO2 separation membranes is known. The progress and strategies in understanding and modification of PEO-based membranes are discussed from various aspects....
The present invention may be particularly useful as a tissue adhesive or as a coating for an intraocular lens (IOL). As an IOL coating, copolymers according to the invention may be used, for example, to promote tissue adhesion for the prevention of posterior capsule opacification....
Our PEX-a (cross-linked polyethylene) pipes are made of high density polyethylene (HDPE) and have excellent chemical, corrosion, temperature and pressure resistance. Meanwhile it has achieved an average 84% of cross-linking degree during the manufacturing process, which is hig...
Polyethyleneglycol and polydimethylsiloxane have a molecular weight of 300-10,000. For an example, a solution of tetrahydrofuran and dimethylacetamide in a volume ratio of 3:1 containing 0.2 w/v% of stenous oxoate and 4,4'-methylenediisocyanate is reacted with dimethylsiloxane at 60C for 2 ...
Therefore, an external H2 source or hydrogen enriched co-reactants is required to promote the conversion. For example, with high-pressure H2, liquid fuels can be generated from polyolefins through hydrogenolysis or hydrocracking on noble metal catalysts15,16,17,18,19,20,21 (Fig. 1a and ...
For example, our customers use it for the following products: chemicals, petrochemicals, minerals, agricultural products, seeds and food products. Because the polypropylene fabric is attached to the inside of the container, the product does not touch the container itself. It creates an ...
by adding wollastonite fibers.Zhou and Yan (2004)andLiet al. (2004), showed an improved wear performance of copper-particle-reinforced UHMWPE. An entirely different composite concept to improve the wear behavior of UHMWPE is the deposition of a hard coating to protect its surface.Santavirta (...
