Commodity resins are often inexpensive and easy to process plastics. They are used in all kinds of applications, including toys, packaging, and consumer products.
Engineering resins are plastic materials that have better mechanical and/or thermal properties than commodity plastics. These high-strength plastics are often resistant to high temperatures, wear, and corrosives. They simulate a range of injection-molded plastics to provide engineers with a wide choice of material properties for prototyping, testing, and manufacturing.
All engineering resins require post-curing under UV light to reach their maximum mechanical properties.
Now, read on to find the right type of resin to fit your needs.
