  Neoprene Popsicle Holder rack knowledge

  Chloroprene rubber glider stands are the polymerization of chloroprene ch2 = ccl-ch = ch2 (2-chloro-1,3-butadiene) or their copolymers with other monomers. The important raw material for the manufacture of chloroprene is acetylene. Various types of polychloroprene can be prepared by emulsion polymerization. The polymerization process is carried out to produce a non-crosslinked, unbranched polymer (so-called α-polymer). Neoprene Popsicle Holder A large number of different forms of chloroprene rubber according to its structure and characteristics can be divided into two categories:

  1, the first category is composed of non-sulfur-containing polymer, synthesis is mainly used when the regulator is thiol;

  2, the second category is the molecular chain containing sulfur chloroprene rubber, sulfur in the form of polysulfide bridge. The conditioning agent used in the manufacturing process is sulfur or sulfur and mercaptan and use. Chloroprene rubber molecular weight distribution is wide, the average molecular weight of 10 to 20 million. Polychloroprene, although having a high degree of unsaturation, still has high chemical stability and resistance to various forms of aging. This is because the double bond carbon atom on the electronegative chlorine atoms to attract the π bond electron layer, reducing the double bond of the electron density, thereby reducing the ability to double bond. At this time the chlorine atom itself lost its activity and responsiveness.

  Density: 1200 ~ 1240kg / m3. Glass transition temperature: -40 ℃. Crystalline phase melting temperature: 40 to 65 ° C.

  The presence of chlorine in the chloroprene allows it to be non-combustible, while the polarity of the polymer makes it resistant to aliphatic hydrocarbons and has a high adhesion to the metal.

  At the beginning of this invention, neoprene has been widely used. Neoprene Popsicle Holder In any case, neoprene's unique combination of physical properties has been applied to more than 1,000 kinds of the whole industry, which is widely known. The

  The nature of cr depends on the microstructure of the polymer, Neoprene Popsicle Holder and its processability depends on the molecular weight of the polymer and its distribution and the number and distribution of the branched and crosslinked, and its chemical properties depend on the chlorine atoms in the carbon atom. The basic variety of cr is the homopolymer of chloroprene. At room temperature with a regular molecular arrangement and crystallization tendency, the crystallinity with the polymer aging and decline. The adhesive type cr which is actually used is polymerized at 20 ° C or lower, and its crystallinity is high.

  Neoprene rubber ice hockey frame important performance

  Resistance range, hot-neoprene has a practical high temperature, continuous application range of 80 ~ 95 ℃, in this range, it shows good physical characteristics, intermittent application, then the extraordinary formula can reach 120 ℃, more than this limit and Does not soften or melt neoprene, Neoprene Popsicle Holder but may cause hardening or elastic loss. Cold - at -20 ℃ to minus 25 ℃ application, the performance is only slightly changed, below this temperature in the embrittlement temperature, (- 40 ℃) before the hardening, extraordinary formula is agreed to application temperature as low as minus 55 ℃.

  Significant anti-wax, fat, oil, lubricants and a variety of petroleum properties.

  Good anti-alkali, dilute mineral acid and inorganic salt solution and other properties.

  Appropriate formula with good ozone, weather performance.

  Can be significantly immersed in water for a long time or buried under the soil.

  Bending resistance, distortion significantly, anti-compression distortion good.
