A PTFE stirring rod is a piece of laboratory equipment used to mix chemicals. It's thicker and slightly longer than a drinking straw, with rounded ends. A stirring rod is used for mixing liquids, or solids and liquids. Stir rods are used as part of proper laboratory technique when decanting supernatants because the contact helps to negate the adhesion between the side of the glassware and the supernatant that is responsible for the liquid running down the side.

Molybdenum is a chemical element with the symbol Mo and atomic number 42 which is located in period 5 and group 6. The name is from Neo-Latin molybdaenum, which is based on Ancient Greek Μόλυβδος molybdos, meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of other metals) in 1778 by Carl Wilhelm Scheele. The metal was first isolated in 1781 by Peter Jacob Hjelm.

Polyvinyl chloride resin generally has a high level of chemical resistance. This may not be seen, however, when the material is exposed to organic chemicals. PVC is also strong and resistant to water and abrasion. This material is very popular in the construction industry. It can be used to produce many items needed in the building process. Those items are often lightweight, long lasting and maintenance-free.

A fidget toy is typically a small object used for pleasant but purposeless activity with the hands (manual fidgeting or stimming). Some users believe these toys help them tolerate anxiety, frustration, agitation, boredom, or excitement.

Puffer toy is a self-regulation tool used with children who have a difficult time sitting still or focusing. The toy helps promote focus and concentration, and keep the body (fingers) busy so they can still sit and focus! Puffer toys are also great for strengthening hand muscles and building fine motor and finger dexterity.

We usually say the strength of products will be increased after closed die forging, as the steel billet is shaped during the forging process, its internal grain deforms to follow the general shape of the part. As a result, the grain is continuous throughout the part, giving rise to a piece with improved strength characteristics. Higher strength will help to increase the working performance of products, thus to longer the serving time. That is why closed die forging is always applied in most applications.

Conductive foam is similar to standard packaging foams but with one crucial difference – the addition of carbon to the polymer mix during the manufacturing process to provide a high level of conductivity. This allows any electric current to pass through the cell structure of the foam and away from the component. Generally, the foam will have permanent conductive performance, meaning it is ideal for multi-trip packaging and in-plant handling applications. Its performance isn’t affected by atmospheric conditions.

Die cut handle paper bags are sturdier than traditional plastic and paper bags. They are rip, puncture, and tear-proof. Die cut handle bags even come with an optional reinforced patch handle or a fold-over handle for extra security, especially when toting around heavier items. Some die cut handle bags have a built-in gusset in the bottom or the side of the bag so it can sit flat on a shelf, countertop, or on the floor without tipping over.

Curtain rod sets can be made of many materials including- wood, metal and plastic. Curtain rods come in almost endless styles and designs. Not all curtain rods are simple straight poles; curved and hinged poles are available from numerous companies, allowing installation in bay windows and around curved walls and corners. Curtain rods can also be shaped like a crane or exhibit a swing arm design.
