Plastic Film Processes

Write By: sukoptfe Published In: Polymers Hits: 1298

Plastic film is a thin continuous polymeric material. Thicker plastic material is often called a “sheet”. These thin plastic membranes are used to separate areas or volumes, to hold items, to act as barriers, or as printable surfaces.

The Environmental Working Group recommends against using dental floss made with PTFE. The group states that "Exposure to PFCs has been associated with kidney and testicular cancer, high cholesterol, abnormal thyroid hormone levels, pregnancy-induced hypertension and preeclampsia, obesity and low birth weight . . . . PFCs pollute water, are persistent in the environment and remain in the body for years. Leading manufacturers of PFCs have agreed to phase out some of these chemicals by the end of 2015, including PFOA, the most notorious, which used to be a key ingredient in making Teflon. Unfortunately, there’s no evidence that the chemicals that have replaced PFOA are much safer."

The valve seat in an internal combustion gasoline or diesel engine is the surface against which an intake or an exhaust valve rests during the portion of the engine operating cycle when that valve is closed. The valve seat is a critical component of an engine in that if it is improperly positioned, oriented, or formed during manufacture, valve leakage will occur which will adversely affect the engine compression ratio and therefore the engine efficiency, performance (power and torque), exhaust emissions, and engine life.

Encapsulated o-rings are o-rings consisting of a seamless and uniform Teflon encapsulation which completely encloses a rubber core material. Elastomer/rubber core material are a choice of Silicone or Viton. The combination of  these components creates an o-ring that is virtually chemically inert and compression set resistant for use in harsh sealing environments. This combination of chemically resistant polymer jacket over a low-compression set elastomer provides unique properties for a range of demanding applications

Plastic Welding Type

Write By: sukoptfe Published In: Polymers Hits: 3434

Plastic welding is welding for semi-finished plastic materials, and is described in ISO 472 as a process of uniting softened surfaces of materials, generally with the aid of heat (except solvent welding). Welding of thermoplastics is accomplished in three sequential stages, namely surface preparation, application of heat and pressure, and cooling.
