Hoffmann Mineral: Las aplicaciones de los Aktisiles (cargas con recubrimientos)

Aktisil

The Aktisil grades, i.e. activated Sillitins, are produced by modifying the surface of Neuburg Siliceous Earth with chemicals, specifically with selected silanes. Several different grades have been developed in order to always ensure optimum coupling between filler and polymer.

In comparison with untreated Neuburg Siliceous Earth, the Aktisil grades, through improved wetting by the polymer, offer manifold benefits in different fields of application:

  • Disperse more readily
  • Improved rheological properties
  • Improved coating resistance
  • Increased anti-corrosion properties

Product

Basis

Treated with

Vinyl acetate resins

(Meth-) Acrylat resins

The Government of Qatar reported its first two new cases of influenza, two foreign children



The government of Qatar announced today the first two cases of influenza A (H1N1) detected in this country, two foreign children who had recently visited United States and Austria, respectively.

The two children who showed symptoms of influenza A new arrival in Qatar, are receiving treatment and are recovering, said Minister of Health Abdullah Al Qahtani, in a statement obtained by the Qatar News Agency.

The first case corrresponde a child two years of New Zealand who arrived last Saturday with his family from Austria, and the U.S. also is a child of two years who came from New York on Sunday with a stopover in Bangladesh, the minister added.

Four other Persian Gulf countries-Saudi Arabia, United Arab Emirates, Kuwait and Bahrain, have detected cases of influenza A (H1N1) in their respective territories.

Blog of the Day: Public Health and more. Contributions of an epidemiologist who is experiencing the epidemic of influenza A H1N1

For reasons that are beside the point I have not been in the eye of the hurricane of the epidemic and the posts I have been hanging over all this time, have been taken from official documents, hence its formal and less personal tone.


This is all very well because it was providing information and making it accessible, especially to fellow Mexicans that they were demanding, and that half of the problem rarely has the opportunity to expunge all sources to extract the necessary information and media misinform rather than inform us.

Note that when a new disease and it is presented in epidemic form, as was the case, health authorities have put in the worst possible scenario because it is better to err on the side by default, but this action has the unintended effect of spreading alarm in the population. Well have been deployed in phases until the pandemic phase 6 in which we have installed a few days ago while waiting to be activated plans for Phase 6, because worldwide it has been decided to continue with the activities of the Phase 5 (containment of the emergence of new cases and isolation of the treatment-known), we can reflect on what has happened and what is happening at this time.

HBCD is Hexabromocyclododecane is end

HBCD is Hexabromocyclododecane. Hexabromocyclododecane has highly brominated and excellent performance in lower loading and reduced effect on polymer properties. It is an additive flame retardant used in a wide range of polymers as well as PP fibres, PS resin, textiles, adhesives and coatings. It is particularly recommended for styrene based systems such as EPS.

Brominated flame retardants (BFRs) have routinely been added to consumer products for several decades in a successful effort to reduce fire-related injury and property damage. Recently, concern for this emerging class of chemicals has risen because of the occurrence of several classes of BFRs in the environment and in human biota. The widespread production and use of BFRs ; strong evidence of increasing contamination of the environment, wildlife, and people ; and limited knowledge of potential effects heighten the importance of identifying emerging issues associated with the use of BFRs. In this article, we briefly review scientific issues associated with the use of tetrabromobisphenol A, hexabromocyclododecane, and three commercial mixtures of polybrominated diphenyl ethers and discuss data gaps. Overall, the toxicology database is very limited ; the current literature is incomplete and often conflicting. Available data, however, raise concern over the use of certain classes of brominated flame retardants. Key words: , , , , , , , .
