Isotope11BF3 PRODUCT DESCRIPTION BF3 PURITY ≥ 99.99 % 11B（Isotopic Enrichment ) ≥99.8 % N2 < 15ppmv O2 / Ar < 15ppmv CO2 < 15 ppmv SO2 < 15 ppm HF < 15 ppmv SiF4 < 15 ppmv BF3 is a gas that is heavier than air and so accumulates in lowlying regions. Its density increases as the temperature BF3 is a colorless suffocating gas.  BF3 does not follow the ideal gas law. Boron trifluoride is treated as a compressed gas. It will be stored in its original packing It is recommended, depending on the flow rate and pressure used, to reduce the pressure of the gas in two stages and to BF3 complexes are typically liquids or solids and therefore may be more easily managed than the high pressure gas.

Boron Trifluoride (BF3) is a non-flammable compressed gas that is used as an acidic catalyst or co-catalyst in a varying array of organic synthesis reactions.  It is one of the strongest Lewis acids (an electron-pair acceptor) reacting readily with chemicals containing oxygen, nitrogen, sulfur and other electron pair donors. PURPOSE: Boron Trifluoride is used as a catalyst for organic synthesis reactions, for the manufacture of synthetic oils and lubricant additives and in the production of high-purity boron isotopes. BF3 gas is used mainly as a catalyst in a large number of reactions: polymerization, esterification, alkylation, acylation, isomerization, sulfonation, nitration, addition, decyclisation APPLICATION: Boron Trifluoride (BF3) can be found in a number of applications. As a strong Lewis acid, BF3’s catalytic properties are used for such reactions as alkylation of aromatic hydrocarbons, polymerization of phenolic and epoxy resins as well as other isomerization, esterification, and condensation reactions. It is used as a source for the manufacture of high-purity boron isotopes such as those found in nuclear waste containment and neutron radiation control applications as well as applications in the semiconductor industry such as the manufacture of semiconductor grade silicone. BF3 is also used as a gas flux for soldering and brazing and in the production of diborane and other boron-containing compounds.

Cascell® RS is specially developed for use as a structural core in connection with vacuum infusion processes, such as VARI and RTM. It is applied in components of aviation, aerospace, sports equipment with resin injection process to reduce the weight. Its mechanical and thermomechanical properties are similar to those of Cascell® WH. Its cell size, which is smaller, achieves an optimal compromise between low resin absorption-about 30% less than for Cascell® WH-and satisfactory bonding of the facings to the core. Thermoforming and shaping Cascell® RS can be easily thermoformed or CNC machined to meet customers’ requirements, bringing tremendous manufacturing advantages. High precision, pre-shaped and ready-to-use foam cores in complex or simple geometries can also be supplied by the Cascell® RS Machining Department.

Ingredient: Sodium butyrate, tannin Concentration: 70% Minimum (sodium butyrate), 20% Minimum (Tannin) Molecular Formula: C4H7O2Na (sodium butyrate)Molecular weight: 110.09(sodium butyrate) C76H52O46(Tannin) 1701.198(Tannin) Description: powder Main properties of butyrate. (1) Growth promotion. Gut health Butyric acid is known to be an important energy source for intestinal epithelial cells, it improve the growth,recovery and differentiation of intestinal villi, increase of the length of villi leads to the increase of absorption surface. villi length increased up to 30%, and feed intake increased up to 10%. (2) strong antibacterial effectr. Butric aicd enters the microbial cell in undissociated form. With the cell it releases protons in an alkaline enviroment which results the decrease of intracellular pH, this decrease of pH influences microbiao metabolism, microbial cells try to excrete proton by using its energy and ultimately end up to death. Main properties of tannin. (1)Hydrolysable tannin can inhibit most of bacteria, fungus and microorganism. (2)Strong astringency of hydrolysable tannin can reduce the flow velocity of chyme in the intestinal tract to increase the digest time and digestibility, and to reduce the incidence of diarrhea, promote growth. (3)Hydrolyzed tannin has strong antioxidant effect, and a European study has shown that tannin has better antioxidant effects than VE and VC at the same concentration. Synergistic effect of butyrate and tannin (1) synergy of reducing wet dropping (2) synergy of antibactiral effect Physical and Chemical Characteristics are as follows: Items Standard Sodium butyrate ≥70% Tannin ≥20% Moisture ≤4% pH Alkali Heavy Metal ≤ 0.001% ﹡﹡﹡﹡﹡﹡﹡﹡﹡ ﹡﹡﹡﹡﹡﹡﹡﹡﹡ Usage: mixing in feed evenly.
