Expert Recommendations
Using the right resins for your program is critical to part performance. The team at PPI knows the strengths, weaknesses and characteristics of most materials, so you can have peace of mind that your project will be a success. Whether you’re using commodity resins or engineered resins, we’ll help you make the right selection.

Commodity Resins
Commodity resins are typically produced in high volumes and are less expensive and easier to process than engineered resins. Materials like Polyethylene resin or Polypropylene resin do not perform well in harsh environments due to poor mechanical, thermal, and chemical properties. Instead, they are often used for applications in the household appliance, construction, and packaging industries.
For those who might be new to the commodity resin selection process, our team of material experts are happy to help. Typically through a consultative discussion, we can work with you to determine the best material for your project. Below are a few common prime, recycled, and re-processed commodity resins:
- Polypropylene (PP)
- Polyethylene (PE)
- High Impact Polystyrene (HIPS)
- Polyvinyl Chloride (PVC)
- Acrylonitrile Butadiene Styrene (ABS)
Engineered Resins
For processes that require a more durable material and solution, engineered resins are a great option. Engineered resins are formulated to stand up to the harshest conditions due to the strength of the resin. Resins like Polyether Ether Ketone have such strong properties that they are often used in metal or wood replacement applications.
At PPI, we have the experience to run even the most challenging materials and the know-how to find alternatives to suit your project. Below are a few of our frequently run engineered resins.
- Nylon (PA6, PA66, and PA12)
- Polyethylene Terephthalate (PET)
- Polybutylene Terephthalate (PBT)
- Polycarbonate (PC)
- Tritan by Eastman (BPA free co-polyester)
- Acetal (POM)
- Polyether Ether Ketone (PEEK)
- Polyvinylidene Difluoride (PVDF)
- Polyether Imide (PEI)
- Polyphenylene Sulfide (PPS)
Custom Resins
On occasion, you may need something that doesn’t quite match common combinations. For customers who require more specialized materials, PPI has the capabilities to provide creative solutions. Our vendors can develop custom resin formulations to meet your requirements, whether it be for radiation shielding, EFI/RMI shielding, noise reduction, vibration reduction, or other needs.
