Plastics & Polymer Processing
Improve polymer processing efficiency, product quality, and regulatory confidence with specialty additives designed for modern manufacturing.
Performance Across Every Processing Stage
Chemistry Across the Polymer Lifecycle
From resin production through recycling and end-use applications, the additives you choose influence performance at every stage of the polymer lifecycle. To produce resins, compounds, films, molded parts, or recycled materials, you need additive technologies that improve manufacturing performance while supporting evolving sustainability and regulatory requirements.
Modern Manufacturing Challenges
The Realities of Polymer Processing
Modern polymer manufacturing requires you to balance efficiency, consistency, compliance, and sustainability under increasingly demanding operating conditions.
Thermal degradation, die lip buildup, plate-out, melt fracture, and gels can reduce throughput, increase scrap, and create inconsistent product quality.
Food-contact requirements, PFAS restrictions, additive migration concerns, and NIAS scrutiny continue to reshape additive selection and formulation strategy.
PCR and PIR materials can introduce variability that negatively impacts melt stability, appearance, and long-term mechanical performance.
Raw material disruptions and regulatory changes can require rapid reformulation, requalification, and operational adjustment.
Manufacturers face increasing pressure to improve recyclability while maintaining production efficiency and end-use performance.
Processors must maintain stable color, appearance, and physical properties across changing materials, operating conditions, and production environments.
Technologies Built for Processing Performance
Specialty Additives for Polymer Processing
You need additive technologies that improve processing efficiency, protect resin integrity, and support modern manufacturing requirements. Dover offers a broad portfolio of specialty additives designed to meet these needs.
- Polymer Stabilization Technologies: Polymeric phosphites and antioxidants help reduce thermal and oxidative degradation during processing while improving long-term material stability and color retention.
- Polymer Processing Aids: Processing aids improve melt flow, reduce extrusion defects, increase throughput, and support cleaner, more stable processing conditions.
- Purging Compound Solutions: Specialty additives help purge systems at operating temperatures, reducing maintenance downtime and minimizing material transition waste.
- Recycling Performance Stabilizers: Recycling stabilizers help restore performance in recycled resins by mitigating degradation caused by multiple heat histories.
Engineered for Real-World Manufacturing
Built for Modern Polymer Manufacturing
Polymer manufacturing requires additives that perform under demanding real-world processing conditions every day. Therefore, to produce food-contact packaging, agricultural films, wire-and-cable compounds, molded parts, or recycled materials, you need chemistries that improve processing efficiency while maintaining long-term product performance.
