A Background on Plastics - Remember Bakelite?

The first synthetic plastics commercially produced were made from phenol and formaldehyde. Over time, the development of urea and thiourea were used to produce foam cushions, melamine, and laminate furniture. Organic chemists, through the 20th century, invented techniques that allowed for plastics to be used for a specific purpose.

Today, most of the synthetic plastics are produced from oil or natural gas which are composed of hydrocarbons that vary in length and configuration.  This results in differing properties which, when added with oxygen, chlorine, fluorine, nitrogen, silicon, phosphorous, or sulfur to their hydrocarbon chains, create different plastics.  For example, Polyethylene (PE) contains only hydrogen and carbon, whereas tetrafluoroethylene (Teflon) contains fluorine in place of the hydrogen atoms. 

This ability serves to create two categories of plastics, thermoplastics, which can be continually and repeatedly reshaped, or recycled, using heat and pressure; and thermosets, which cannot be reshaped once formed. Examples of thermosets would be polyurethane, epoxy, and such.  Thermoplastics make up approximately 85% of all plastics produced, with thermosets being the other 15%. 

So, when you are considering what thermoplastic would best serve your project needs, call on the specialists at Polystar-Technologies for help!

Applications for Sintered Porous Plastics

Sintered porous plastic materials are now being used in ever-expanding marketplaces with applications that offer improved healthcare, medical knowledge, and in the diagnosis and treatment of diseases.  Polystar Technologies' sintered, microporous thermoplastic media provides solutions to serve applications such as wicking, absorption & adsorption, acoustic dampening, silencing, muffling, and muting, filtration, barrier protection, diffusion, fluidization, venting, and aerating & sparging.

Made from thermoplastic polymers such as polyethylene or polypropylene, these sintered materials can be produced with pore size ranges of  5 to 350 micron and typical void volumes between 30 and 50 percent but, which can be produced up to 70%.  Sintered porous plastics are available in a varied of shapes and sizes, as well as with defined pore size distribution.  Combining this with the exceptional robustness, chemical resistance, and chemical compatibility, sintered porous plastics are resistant to many acids, bases, organic chemicals, and temperatures up to 230°F (110°C).

According to Mike Lien, President of Polystar Technologies, "We take great pride in the quality of our products and customers' satisfactions, which is why we closely engineer and control the pore size and void volume through the selection of polymers used and process controls."
