HYAMPP^® Catalysts and Donors

HYAMPP^® non-phthalate catalysts are Grace’s next-generation polypropylene catalyst platform — designed to give resin producers the flexibility to meet today’s performance demands and tomorrow’s industry shifts.

Polypropylene (PP) producers face growing demands for performance, efficiency, compliance, and sustainability. Choosing the right catalyst has never been more critical.

Legacy systems, including Grace’s own LYNX^® catalysts, helped define the last generation of PP production. But the industry has moved on. Today’s producers need flexibility, cleanliness, and efficiency — without compromise.

That’s why Grace developed HYAMPP^®, a next generation non-phthalate catalyst platform designed to meet today’s polypropylene production demands and anticipate tomorrow’s. It helps resin producers align with global regulatory standards and brand-owner sustainability goals, while integrating seamlessly with many process technologies including: Spheripol^®, Hypol^®, Innovene^®, Novolen^®, and Spherizone^®.

Seamless Operational Performance

HYAMPP^® catalyst is engineered to reduce operational losses and improve plant efficiency:

• Optimized catalyst morphology minimizes fines and reactor fouling, reducing unplanned downtime
• High catalyst activity supports lower ash levels (<30 ppm), improving resin cleanliness and enabling additive package optimization
• Advanced donor technology enhances reactor stability and throughput, helping producers increase production rates and reduce operational costs

More uptime and less waste. HYAMPP^® catalyst keeps your plant running cleaner and faster.

Broad Product Capability

HYAMPP^® catalyst enables production of both commodity and specialty grades, supporting a wide spectrum of polypropylene resin types:

• From very low to very high xylene solubles
• From very low to very high melt flow rate (MFR) grades
• From homopolymers to random and impact copolymers

This breadth allows producers to cover a large spectrum of applications — from packaging to automotive — and adapt quickly to changing industry needs with fewer catalyst changeovers.

HYAMPP^® catalyst gives you the flexibility to serve more markets with fewer changeovers.

Premium Product Enablement

HYAMPP^® catalyst empowers producers to expand their product portfolios with differentiated, higher-value resins. Its advanced donor system and tailored hydrogen response enable:

• Better comonomer incorporation for enhanced clarity, downgauging, and mechanical properties
• A broad xylene solubles response for fine-tuned resin characteristics
• Exceptional hydrogen response — enabling high melt flow rates in-reactor without peroxides, reducing energy use and plant emissions, and supporting faster grade transitions and reduction of off-grade production

This unlocks access to premium applications like battery separators, medical packaging, and other high-performance films — helping producers elevate their product mix.
