Bromoethane, also known as ethyl bromide, is a chemical compound of the haloalkanes group. It is abbreviated by chemists as EtBr (which is also used as an abbreviation for ethidium bromide ). This volatile compound has an ether-like odor.
In the example, there is a bromo-substituted -CH 2-CH 2 - subunit. 1-Bromoethane-1,2-diyl is chosen in preference to 2- bromoethane-1,2-diyl as the former has a lower locant for the bromo-substituent. The preferred CRU is therefore oxy(1-bromoethane-1,2-diyl) and the polymer is thus named poly[oxy(1-bromoethane-1,2-diyl)].
The filter element matrix consists of molded sintered polyethylene (PE) with a reinforced mounting header. An additional PTFE-coating gets into the pores of the PE-basic body and forms a micro-porous, non-sticking surface resulting in surface-loaded filtration. [7] This combined material is chemical resistant and unaffected by slight moisture.
While coating a substrate with conventional polymers requires several steps, plasma polymerization accomplishes all these in essentially a single step. [1] This leads to a cleaner and 'greener' synthesis and coating process since no solvent is needed during the polymer preparation and no cleaning of the resultant polymer is needed either.
Extrusion coating is the coating of a molten web of synthetic resin onto a substrate material. It is a versatile coating technique used for the economic application of various plastics, notably polyethylene, onto paperboard, corrugated fiberboard, paper, aluminium foils, cellulose, non-wovens, or plastic films. It was. first developed in the ...
Plastic coating is a term that is commonly used in technology but is nevertheless ambiguous. It can be understood to mean the coating of plastic (e.g., metallization of plastics [ 1 ] ) or the coating of other materials (e.g., electrical cable ) with plastics.
The first heat-shrinkable sleeves were introduced [when?] as polyethylene pipeline coatings started to replace bituminous or tape coatings in the oil and gas industry. At the time, the processing for polyethylene to make the sleeve backing was new technology and the adhesives used in sleeves were much the same as those used on pipeline coating.
This would be more effective than the current technique of releasing a high dose of drugs into the body and counting on some of it to navigate to the afflicted area. The base layer for an effective coating for an implant is DMLPEI/PAA, or linear N, N-dodecyl,methyl-poly(ethyleneimine) / poly (acrylic acid). [7]
