Polyester Engineering Property Data
MatWeb has product data on about 6000 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 need to narrow down the list of results to a polyester product with certain performance criteria, then
MatWeb's Advanced Search or Property Search Page is a good place to start.
You can select 'Polyester' from the list of category choices under thermoplastic or thermoset headings (or be even more restrictive and
select only PBT) along with the appropriate property choices. For example, if you have an application
that demands a flame retarded, anti-static thermoplastic polyester grade, you can enter a minimum UL94
Flammability rating of V-2 and a maximum surface resistance of 108 ohms 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 a more manageable number of 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.
