Advantages of Aluminium Flip off Seal

图片
  As a   Flip Off Seal Manufacturer , share with you. The advantages of aluminum-plastic composite lids, metal packaging is an important part of the modern packaging industry, and easy-open lids are made of safe, hygienic, non-toxic and odorless high-quality materials used in canned food, beverages and other industries, while being safe and hygienic, convenient to eat, and easy to transport Recycling, not polluting the environment, and more and more popular with consumers. What are the advantages of aluminum-plastic composite cover? Aluminium Flip off Seal 1. The aluminum-plastic composite cover is made of high-quality aluminum material, which is hygienic, will not rust, and is convenient to open without auxiliary tools. After opening, the bottle cap is destructive and can effectively prevent theft. 2. The aluminum-plastic composite cover has the advantages of good cushioning, shock resistance, heat insulation, moisture resistance, chemical corrosion resistance, etc., and is n...

Are rubber stoppers chemical-resistant?

图片
In the world of laboratory equipment and industrial applications, the choice of materials plays a pivotal role in ensuring safety, efficiency, and longevity. One critical component that often takes center stage is the   humble rubber stopper . Today, we delve into the depths of this unassuming device to answer a question of paramount importance: Are rubber stoppers genuinely   chemical-resistant? What Makes Rubber Stoppers Tick? Before we dive into the chemical resistance of  rubber stoppers , let's unravel the composition of these versatile devices. Typically crafted from natural rubber or synthetic polymers, rubber stoppers serve as sealing mechanisms for a myriad of containers, vials, and laboratory apparatus. The Chemistry Behind Chemical Resistance Natural Rubber vs. Synthetic Polymers: A Clash of Titans Natural Rubber's Innate Resistance Natural rubber, derived from the latex of rubber trees, exhibits inherent chemical resistance. The unique molecular structure...

Why Not Use Butadiene for Synthetic Butyl Rubber?

图片
As a   Bromobutyl Rubber Stopper , let me share with you. Because the use of isoprene (2-methyl du1, 3-J1 ene) as a monomer has completed the industrialization. Butadiene can be synthesized into butyl rubber, and the precursor of butyl rubber was obtained by copolymerizing isobutylene and butadiene with aluminum trichloride in ethyl chloride solvent. Bromobutyl Rubber Stopper At present, there are many kinds of butyl rubber processes, and it is often used to prepare a 25% solution of refined isobutylene (97%-98%) and isoamylene (2%-3%) in diluent methyl chloride, and Quench to -100°C (here is a methyl chloride solution, not an aqueous solution; elementary school students can easily make mistakes); At the same time, the catalyst chloroform is dissolved in methyl chloride and quenched to -100°C. Two liquid streams are continuously injected into the polymerization vessel and the polymerization vessel is kept at 100°C to obtain a slurry of butyl rubber fine ions. The cooling method is ...
