The short answer
Download resinbridge-resin-properties.csv (51 resins, 22 columns). It has typical ranges for density, tensile strength, flexural modulus, notched Izod impact, heat deflection at 1.8 MPa, 24-hour water absorption and mold shrinkage, plus drying, clarity, chemical resistance, outdoor/UV and relative cost notes. It is the same data behind the resin comparison tool, free under CC BY 4.0.
What is in the file
- Ranges, not single values. Each property has a _min and _max column in metric units (g/cm³, MPa, GPa, J/m, °C, %).
- Test basis. Typical values from producers’ published data sheets for general-purpose grades. Heat deflection is at 1.8 MPa (264 psi). Water absorption is 24-hour immersion.
- Text columns. Drying need, clarity, chemical resistance, outdoor/UV behavior and relative cost, in plain words.
- page_url. A link to the ResinBridge page for each resin, with more detail and grade notes.
Typical values are not specifications. For a real part, use the data sheet for the exact grade and the lot COA. See how we check our data.

Common questions
Can I use this data in a class, report or app?
Yes. The dataset is free under the Creative Commons Attribution 4.0 license (CC BY 4.0). Use, share and adapt it, including commercially, as long as you credit ResinBridge and link to this page.
Where do the numbers come from?
They are typical ranges compiled from producers' published data sheets for general-purpose grades of each resin. They are not specifications. For a real part, use the data sheet for the exact grade and the lot COA.
Why are some cells blank?
Blank means the property is not usually reported for that resin, or a notched Izod specimen does not break. Check the grade's data sheet.
How often is it updated?
When we revise the resin comparison tool or a property page. The date on this page shows the last update.
