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.

Chemical drugs, anesthetics PROCAINE Basic information Originally used to relieve pain caused by intramuscular injection of penicillin, it is also used in dental surgery. It acts primarily as a sodium channel blocker. Procaine was first synthesized in 1905 by the German chemist Alfred Einhorn, a little later than amilocaine. Alfred Einhorn's trade name was Novacaine, based on Latin. (Nova- means "new," and -caine is a common end-of-word for narcotic alkaloids.) It was introduced into clinical use by surgeon Heinrich Braun, and before the advent of stovaine and procaine, cocaine was the most commonly used local anesthetic.

Phenacetin Basic information Chemical drugs, antipyretic and analgesic drugs, antiviral drugs, anti- inflammatory drugs, pharmaceutical chemical raw materials, botanicals Antipyretic analgesic, used for the treatment of fever, headache, neuralgia, etc. Antipyretic effect is stronger than analgesic effect. The efficacy intensity is similar to that of aspirin, the effect is slow and lasting, and the toxicity is low. The study shows that this product and its metabolite paracetamol have antipyretic effect. Because the enzyme inhibitors of phenacetin can not be converted to paracetamol, can still show a significant antipyretic effect. Therefore, the antipyretic effect of the raw material was not only caused by its active product, acetaminophen. The mild analgesic effect of finacetin is generally maintained for 3-4 hours. The synergistic effect with salicylic acid can enhance the analgesic effect. Clinically, it is mainly used for antipyretic analgesia of small animals. It is also a component of APC Tablets.
