Middle ring tubes always come in 3 parts, the top tube, the base tube, and the middle connection part. The middle rings are always in gold or silver color, it looks in higher quality and standard. The diameter and length can be customized. With the middle ring, the tube can keep tight enough.
Double tubes are also classic tubes to pack the cigars. It comes with two tubes, one outer tube, and one inner tube. When pulling out the tube, it gives a good feeling of “pop-out”. It is a good tube case to pack a single cigar.
The torpedo cigar tubes come in a torpedo shape with sharp tips. It is used to pack these cigars with sharp tips also. These plain cigar tubes are good for short cigars with rolled sharp tips. The torpedo tubes are also with three parts and a middle ring.
In our daily life, there are many common silicone products. Such as silicone nipple, silicone baking molds, silicone gloves, silicone dinnerware and etc. There are also silicone straws in the juice machine, silicone seal gasket in the industrial machine. Peoples may ask what’s silicone? And what’s silicon, silica?
Silicon is not the same thing as silicone. Silicon is one element in the periodic table, abbreviated to “Si”. Its atomic number is 14, and the atomic mass ratio is 28.085. Silicon belongs to the third period on the periodic table of the IVA group of metal-like elements。
Silicon is an extremely common element in nature. It rarely appears as element form in nature, most widely found in rocks, gravel, and dust in the form of complex silicates or silicon dioxide. Such as Feldspar KAlSi3O8, kaolin Al2Si2O5(OH)4, talc Mg3(Si4O10)(OH)2, mica KAl2(AlSi3O10)(OH)2, asbestos H4Mg3Si2O9 and etc. In the earth’s crust, silicon is the second most abundant element (weight ratio is 26.4%), follow the oxygen (49.4%)
Silicon is a metalloid element. Silicon can be oxidization to silicon dioxide like metal elements. This silicon dioxide is also known as silica. So Silica is silicon dioxide, with the chemical formula: SiO2. Si(Silicon) can be oxidized reaction to SiO2(Silica / Silicon dioxide). SiO2 can also redox reaction to Si. We just need to provide suit chemical reaction conditions.
Silicone is also known as siloxanes or silicone polymer. It is a man-made polymer made up of silicon (Si), oxygen (O), carbon (C), and hydrogen (H). Silicones polymer is produced to chemical forms including Silicone Oil, Silicon Resin, and Silicone Rubber. They depend on molecular length, weight, and molecular construction (linear or mesh). The key functional group is in the Quora images as follows.
Silicone Oil is one kind of oligomer. Silicone oil is non-volatile, non-congealable, low-viscosity, and insulation at 200℃. So it’s high-quality lubricating oil especially used in the high-temperature machine system.
Silicon Resin has mesh and 3D construction. It’s flexible resin, can resist high-temperature and especially good electrical insulator. It can be used as the insulation coating material, adhesions, and so on.
Silicone Rubber includes Liquid Silicone Rubber(LSR), which are mainly used in the injection molds machine to make silicone products, such as silicone nipper and transparent silicone straws. And there’s also the solid silicone rubber, need to process in the rubber mixing mill, then heating pressure and vulcanized to silicone products, such as the silicone baking mold, silicone gloves, silicone cups and etc.
So the silicone products on our website are also called silicone rubber. The silicone rubber products are made from natural silicon dioxide.
The normal chemical synthesis of the silicone polymer is the direct synthesis process. That’s Silicon (Si) powder and halohydrocarbon (dichloromethane (CH3Cl)or chlorobenzene(C6H5Cl )) reaction at high-temperature and catalyst conditions, get the mixed product Alkyl halosilane(main is R2SiCl2 and RSiCl3).
When we want to make Silicone Rubber, we need high purity of halosilane (CH3)2SiCl2, purity ratio about 99.9%. The halosilane is extremely easy hydrolysis to silanol (CH3)2Si(OH)2. Silanol vulcanized to silicone rubber by the condition of high-temperature, vulcanizing agent, and filler.
While the silicon resin is the special ratio of halosilane (CH3)2SiCl2 and CH3SiCl3 mixture hydrolysis and condensation polymerization reaction to the mesh polymer.
In the next article, we share how to make silicone rubber products in our factory.
