Custom Plastic Compounding

High-Performance Compounds. Proven Results.

Create stronger, more sustainable materials with Cascade Engineering. Our material scientists work directly with your team to engineer resins that are lighter, tougher, and better for the planet.

Cascade’s Custom Compounding

Our compounding process blends polymer chemistry, recycled content, and advanced additives to create resins ready for real-world applications. From automotive components to municipal infrastructure, every formulation is developed with precision and verified in our A2LA-accredited lab.

We can integrate recycled or bio-based feedstocks, colorants, fillers, and reinforcements to match your technical and environmental goals. Our team offers smooth production and repeatable quality at scale.

Frequently Asked Questions

What is plastic compounding?

Plastic compounding is the process of blending base polymers with additives, fillers, and reinforcements to create materials with enhanced performance properties.

Can Cascade use recycled materials in custom compounds?

Yes. We regularly integrate post-consumer and reclaimed plastics into new formulations while maintaining consistency and quality.

How does custom compounding improve product design?

By adjusting factors like stiffness, strength, or color, custom plastic compounding allows engineers to achieve better part performance, durability, and sustainability.

What types of additives can be included in custom compounds?

We use a range of additives, including colorants, UV stabilizers, flame retardants, lubricants, impact modifiers, and reinforcements like glass or mineral fibers.

Can Cascade match or improve an existing material formulation?

Yes. Our materials lab can reverse-engineer or optimize your current resin for better flow, performance, or recyclability.

Does Cascade provide testing and validation for compounds?

Yes. Each formulation is tested in our accredited lab to confirm performance and compliance with your specifications.

What’s the difference between compounding and blending?

Blending combines ready-made materials, while compounding creates entirely new formulations by mixing polymers and additives under precise conditions.
