  As a   Bromobutyl Rubber Stopper Supplier , share with you. The rubber has good comprehensive performance and is widely used. Mainly include: ①Natural rubber. It is made from the latex of the para rubber tree. The basic chemical composition is cis-polyisoprene. Good elasticity, high strength, and good overall performance. ② Isoprene rubber. The full name is cis-1,4-polyisoprene rubber. A high cis synthetic rubber made from isoprene. Because its structure and properties are similar to natural rubber, it is also called synthetic natural rubber. ③ SBR. Abbreviated as SBR, it is made by copolymerization of butadiene and styrene. According to the production method, it is divided into emulsion polymerization styrene butadiene rubber and solution polymerization styrene butadiene rubber. Its comprehensive performance and chemical stability are good. ④ Butadiene rubber. The full name is cis-1,4-polybutadiene rubber, abbreviated as BR, which is made by polymerization of butadiene. Com...

  As a   Aluminium Flip off Seal Supplier , share it with you. The advantages of aluminum plastic cover are mainly reflected in three aspects: low cost, strong environmental protection, and rich colors. Especially in terms of color. The aluminum-plastic cover greatly meets the demand for more and more high-end products and adapts to the increasingly sophisticated development trend of Chinese packaging. Aluminium Flip off Seal According to the surface texture, aluminum-plastic bottle caps are divided into two types: high gloss bottle caps and silk bottle caps. The former is specially treated, and the surface of the cap is as bright as a mirror. In addition, the combination of surface bronzing technology and screen printing and pad printing can significantly improve the overall effect and anti-counterfeiting level of the product. The latter is made with patented technology and special craftsmanship, and its appearance has a strong velvet texture. At the same time, due to the use...

  As an   Aluminium Flip Off Seal Manufacturer , share with you. Pharmaceutical aluminum-plastic composite covers are mainly used in medical, chemical packaging and other industries. Different industries have different requirements for medical aluminum-plastic composite covers. In order to let everyone know more about medical aluminum-plastic composite covers, let us come together today. Take a look at how to judge the quality of the medicinal aluminum-plastic composite cover by its appearance. Aluminium Flip off Seal 1. Check the riveting point. The size of the riveting point should be the same, the surface should be smooth, the thickness should be uniform, there is no burr around, and the color should be the same as the color of the plastic cover itself. The diameter of the riveting point should be 1-1.5mm larger than the diameter of the riveting hole of the aluminum cover. The flanging type medicinal aluminum-plastic composite cover has a flanging length of 1-1.5mm). The au...

  As a   Rubber Stoppers with DMF Supplier , share with you. At present, there are mainly two types of halogenated butyl rubber used in the production of rubber stoppers: chlorobutyl rubber and bromobutyl rubber. Comparison of two rubbers: Bromobutyl Rubber Stopper 1. Both chlorinated butyl rubber and bromobutyl rubber are modified products of butyl rubber, collectively referred to as halogenated butyl rubber. The purpose of modification is to improve its processing performance and expand the scope of application. 2. Stabilizer content: Because the bromine element in bromobutyl rubber is relatively active, the storage stability is low, and self-vulcanization is easy to occur, so it is necessary to add a stabilizer to the rubber (generally epoxy soybean oil, the content is 1.3 % By weight or so); and the chlorine element in chlorinated butyl rubber is more inert than bromine element and has high storage stability. Generally, no stabilizer is added, and the intrinsic purity is h...
