What is the difference between bromobutyl rubber and chlorobutyl rubber?

Butyl rubber is synthesized from petrochemicals and is a copolymer of isobutylene and a small amount of isoprene. Subsequent halogenation produces halogenated butyl rubber—usually bromobutyl or chlorobutyl. What is bromobutyl rubber? Bromobutyl rubber: is a terpolymer of isobutylene, isoprene, and brominated isoprene. Bromobutyl rubber   (BIIR) is an isobutylene-isoprene copolymer elastomer containing reactive bromine. Because bromobutyl rubber has a substantially saturated backbone of butyl rubber, it has many performance characteristics of butyl polymers, such as higher physical strength, better vibration damping properties, low permeability, aging resistance and Weather-resistant. The invention and use of the halobutyl rubber innerliner has in many ways enabled the modern radial tire. The use of these polymers in tire innerliner compounds can improve pressure holding properties, improve the adhesion between the innerliner and the carcass, and improve tire durability. Advantage: ...

Annealing process of pharmaceutical glass bottles

  Each medicinal glass bottle is annealed, the role of annealing is to eliminate or reduce the thermal stress of the glass bottle to the allowable value of the heat treatment process, after annealing, it is not easy to rest in extreme cold and heat. Annealing of glass bottles is to eliminate and reduce the stress. Glass bottles undergo drastic and uneven temperature changes during the manufacturing process, which leads to thermal stresses in the glass product. This thermal stress can reduce the strength and thermal stability of the glass bottle, and even lead to self-cracking of the glass bottle.     Pharmaceutical glass bottles  Stress in glass is generally divided into three categories, namely thermal stress, mechanical stress and structural stress.   1. thermal stress: glass products due to temperature differences in the stress called thermal stress, according to its existence can be divided into temporary stress and permanent stress. (1) temporary stress: th...

In slurry pumps, the impeller and the inside of the pump casing are always exposed to the slurry and must therefore be protected against wear accordingly. "The choice of material for the impeller and pump casing is as important as the choice of the pump itself!"     Three different conditions that generate wear in slurry pumps. Abrasion, erosion, corrosion 1.Wear Wear is divided into three main types. In slurry pumps, we have mainly abrasion and low stress wear. The rate of wear depends on particle size and hardness. Wear in  slurry pumps  occurs in only two areas. a. Between the impeller and the fixed inlet. b. Between the shaft sleeve and the fixed packing. 2. Erosion This is the main wear of the slurry pump. The reason is that the particles in the slurry hit the material surface at different angles. The way the pump is operated can seriously affect erosion wear. In general, erosion wear is lowest at BEP flow rates and increases as the flow rate increases and decre...

Bromobutyl rubber plugs have good resistance to cold and aging

What is bromobutyl rubber? Bromobutyl rubber  is derived from the halogenation of butyl rubber with bromine in a continuous process. It is structurally similar to chlorobutyl rubber and is produced by the same halogenation process. Another thing to know is whether chlorobutyl rubber contains latex. Plugs made from natural red rubber and plugs made from chlorobutyl-isoprene blends contain natural rubber latex. All other plugs do not contain latex. What are the uses of polyisobutylene? Polyisobutylene is a synthetic rubber that is used primarily in the manufacture of tire inner tubes. Other applications include adhesives, pesticides, caulks, sealants, paper and paper pulp, and chewing gum. Does bromobutyl rubber contain latex? There are several types of latex allergies. The best way to prevent allergic reactions is to avoid contact with latex altogether. The plugs of the mentioned rubber injection 2 ml and 20 ml vials are made of synthetic bromobutyl rubber and do not contain latex. ...

Glass dropper bottle rubber cap aging, should be replaced in a timely manner

In the production process of glass drip bottle, not only should the pharmaceutical low borosilicate transparent glass tube within the tolerance range of industry regulations, but also to achieve the requirements of no burr, no bubble, no mold spot. Glass glass drip bottle manufacturers strictly control the size and shape of the   glass glass drip bottle   during the production process, and clean and pack the glass glass drip bottle after the production is completed.     1. Different classification Glass dropper bottle: divided into fat belly glass dropper bottle and common glass dropper bottle. It consists of a rubber nipple and a pointed glass tube. Rubber-tipped glass dropper bottle: there are several forms of straight, straight with cushion ball and curved with cushion ball. The specifications of the plastic-tipped glass drip bottle are indicated by the length of the tube, commonly used are 90mm and 100mm. Plastic-tipped glass dropper bottle 0.05ml per drop. 2. Di...
