latex

 [la´teks] (L. “fluid”)
1. any of various white viscid fluids secreted by certain plants; the variety from Hevea brasiliensis, the rubber tree, was formerly the main source of commercial rubber. Allergic reactions to natural latex are an important cause of type IV hypersensitivity reactions. See also latex allergy.
2. any of several synthetic fluids resembling natural latex, including polystyrene and polyvinyl chloride; these are not causes of latex allergy.
latex agglutination test (latex fixation test) a diagnostic study used to detect certain antibodies in body fluids; latex particles are used as passive carriers, and particles clump together following the addition of the antibody. One use is as a serologic test for rheumatoid factor in diagnosis of rheumatoid arthritis.

la·tex

(lā'teks),
1. An emulsion or suspension produced by some seed plants; it contains suspended microscopic globules of natural rubber.
2. Similar synthetic materials such as polystyrene, polyvinyl chloride, etc.

latex

(lā′tĕks′)
n. pl. latices (lā′tĭ-sēz′, lăt′ĭ-) or latexes
1. The colorless or milky sap of certain plants, such as the poinsettia or milkweed, that coagulates on exposure to air.
2. A polymer emulsion consisting of such sap obtained from rubber trees, used to manufacture various thin elastic products such as balloons, disposable gloves, and medical and contraceptive devices. Some people are allergic to this substance. Also called natural rubber latex.
3. A similar material made from polymers derived from petroleum; synthetic latex.
4. Latex paint.

latex

A lactescent gel of molecular homogeneity, obtained from plants and composed of microglobules of natural rubber; latex may be airborne, and is present in latex gloves, dental rubber dams, condoms, barium enema catheters, other medical devices, and tires/tyres Lab medicine Latex-like particles–eg, neoprene, polyvinylchloride, polystyrene, and synthetic 'rubbers'; latexes are inert vehicles that may be used to carry antibodies or antigens in latex agglutination immunoassays; or rubber latex-like plastic monomer used to manufacture minute plastic beads of polystyrene

Patient discussion about latex

Q. I went out the other day with an ex, and things got “interesting” and then he refused to wear a condom saying he is allergic to the latex now! I mean, we’ve been together a few years before and he didn’t have any problem then. So how can he be allergic to latex all of a sudden? (we didn’t have unprotected sex if any of you wondered)

A. I doubt an allergy to latex developes over the years out of the blue, but it is not impossible that someone suffers from somewhat an allergy at a lesser extent that does not bother him and then later developes a stronger reaction to the substance.

Commercial styrene-acrylic and pure acrylic latexes with MFFT of 17 and 21[degrees]C, respectively, were used in the MFFT and AFM evaluations as well as in the semi-gloss and flat paint formulations.
The measurements of the MFFT of the latexes are carried out on MFFT bar.
The dispersion of pigment particles in the nanocomposite latexes and the blended latexes was further evaluated by TEM, and the typical TEM micrographs were shown in Figure 3.

Several recent publications reporting good block resistance involve either latex blends or VAE/polyurethane hybrid compositions.(7-9) The component latex responsible for antiblocking properties is either a vinyl acetate homopolymer (7) or acrylic latex containing a sterically hindered alkoxylated silane monomer.(8) Table 2-VAE and Acrylic Latexes for the Blend Study Latex T.sub.g]([degree]C) Mv ([mu]m) WAM VAE 11 0.380 0 Acrylic A 20 0.150 2.5X Acrylic B 39 0.075 2.5X Acrylic C 0 0.090 2.5X Acrylic D 0 0.133 2.5X Acrylic E 0 0.138 IX
The number of applications for nonwovens is rapidly expanding and we have four lines of versatile latexes to meet the industry's ever-changing demands:
HyStretch Elastomeric Latexes--These unique elastic materials have the unusual ability to stretch and recover better than most rubber latexes. They also have excellent heat and light stability properties.
However, such studies have only focused on conventional monomodal latexes, and not on bimodal latex dispersions.

Also, it was found that these high-temperature water-extended latexes showed much lower minimum film formation temperatures (MFFTs) than those of their original lightly carboxylated, high-[T.sub.g] latexes.
Dow has been providing latexes for film coat applications globally for years.
The colloidal interactions of HASE associative polymers and latexes in the presence of surfactant are complicated and subject to a number of variables.
