Polyester Engineering Property Data

 

MatWeb has product data on over 2900 different grades of thermoplastic and thermoset polyester - PBT, PCT, PET, polytrimethylene terephthalate, polyester thermoplastic elastomers (TPEs), thermoset alkyds, polyester-based fiberglass, and thermoset SMCs and BMCs.  This page will help you to navigate through MatWeb to find the information that you need.

• If you would like to scan the polyester entries in MatWeb, then the MatWeb Material Category Page is a good place to start.  You can select 'Polyester' from under either the thermoplastic or thermoset polymer headings, or specific polyester types such as 'Polyethylene Terephthalate (PET)', and you will be presented with a list of descriptive names.  Polyester-based thermoplastic elastomers (TPEs) or polyurethanes are categorized separately.  Many users start by viewing MatWeb's Overviews - 'generic' polymer entries at the top of the results set that give typical values and ranges that cut across the various manufacturers' polyester product lines.

  You may also select from the drop-down lists of Plastic Manufacturers/Compounders or Polyester Trade Names available from MatWeb.

• If you are looking for a polyester product with certain performance criteria, then MatWeb's Property Search Page is the place to start.  You can select 'Polyester, TP' from the list of category choices (or be even more restrictive and select only PBT) along with the appropriate property choices.  For example, if you have an application that demands flame retarded polyester grades with a low coefficient of friction, you can enter a minimum UL94 Flammability rating of V-2 and a maximum coefficient of friction of 0.4 in your search criteria.

  This same strategy can be used to find fiber-reinforced thermoplastic polyester composites.  You can again select 'polyester' from the list of thermoplastics in the category box and specify a minimum flexural modulus of 9 GPa, for example.  This example returns a few hundred polyester grades; generally only grades with at least 30% glass or carbon fiber reinforcement are stiff enough to meet this flexural modulus requirement.  You can go one step further and eliminate the glass fiber reinforced grades by stipulating a maximum density of 1.45 g/cc.  Now only a few dozen carbon fiber reinforced polyester grades are returned - you can then review each of the complete property information datasheets, including properties such as tensile strength or dielectric constant.

  Users who choose to register with MatWeb can take advantage of even more powerful search tools in the Advanced Search page. This allows users to create complex searches from both text and property criteria.
