Guide to Choosing the Best Polyurethane Material

Plan Tech for over 30 years has produced millions of parts for numerous applications. Frequently we will be presented with a problem for a custom application or better performance out of OEM parts. Plan Tech can match OEM parts to print or from a sample part out of high-quality urethane from world leading chemical companies.

There are two main types of urethane resins polyester and polyether. For the most part polyether material is incredibly tough and a go-to choice for most applications. When abuse or wear items are presented to Plan Tech we will learn exactly what the application is and find the best material we feel suited for excellent product performance and service life.

 

Plan Tech exclusives use high quality cured agents like 4,4′-Methylenebis(2-chloroaniline) (MOCA, MBOCA, bisamine) with a decades-old proven performance that ensures the highest level of urethane performance. Plan Tech also has a variety of additives in addition to FDA requirements.
