Resins Tailored for Unique Applications
Specialty compounds are custom-engineered resin blends designed to meet specific performance criteria that standard materials can’t fulfill.
Offering enhanced mechanical, thermal, chemical, and electrical properties, these compounds provide innovative solutions for demanding industrial, automotive, medical, and consumer products. PFAS-Free, high specific gravity, metal/x-ray detectable or IR transparent custom colors are just some examples of what we can do for you.


Versatile Applications Across Industries
Specialty compounds deliver tailored solutions for products requiring unique performance features in various sectors.
- Automotive structural parts
- Electrical connectors
- Medical device components
- Consumer electronics housings
- Industrial machinery parts
- Protective gear
- Filtration system components
- Military and ASTM call-out certified
- Material handling devices with tailored wear & friction properties
- And more
