As flame retardant requirements continue to evolve, formulators are often faced with a familiar challenge: finding alternatives to legacy chemistries that don’t introduce new complexity. Moving away from chlorinated phosphate ester (CPE) and triethyl phosphate (TEP) based systems is no longer just a regulatory discussion, but a formulation and processing decision that must work in real production environments.
The ANTIFLAME® PCR33 family of halogen free flame retardants were developed with that reality in mind. Rather than offering a single, fixed solution, ANTIFLAME® PCR33 provides a flexible family of high performance, liquid, phosphorous based flame retardants designed to make formulation updates easier, not harder for a broad range of chemistries.
Reformulating Doesn’t Have to Be Complicated
One of the biggest concerns when changing flame retardant systems is the risk of disrupting existing formulations. Viscosity changes, handling challenges, and loading constraints can quickly turn a simple substitution into a major redevelopment effort.
The ANTIFLAME® PCR33 family of products were engineered specifically to reduce those barriers. By combining high flame retardant efficiency with processing friendly properties, the ANTIFLAME® PCR33 platform allows formulators to maintain control over their formulations while upgrading performance.
Key attributes of the ANTIFLAME® PCR33 platform include:
- Efficient, easy to use systems designed for smooth integration
- Excellent flame retarding performance with low VOCs
- Halogen free and CPE free liquid properties
- Commercial production in the USA and other global sites, supporting supply chain stability
The result is a practical path to modern flame retardancy without sacrificing formulation ease.
A Flame Retardant Family Designed for Flexibility
Formulation requirements vary widely across applications, processing conditions, and performance targets. Different systems place different demands on a flame retardant, whether related to viscosity, reactivity, acidity, or allowable loading range.
To address this reality, ANTIFLAME® PCR33 is offered as a family of products, giving formulators the flexibility to select the options that best align with their specific application needs.
Within the ANTIFLAME® PCR33 family, the product can be configured for different carrier options, reactivity, and processing behaviors. This customized approach allows formulators to tailor flame retardant performance to their formulation across a broad range of applications, including polyurethane foams, CASE systems, electronic encapsulations, and composites.
Performance Aligned with Formulation Priorities
Ease of use doesn’t mean compromising on performance. Across the ANTIFLAME® PCR33 family, flame retardant efficiency remains a consistent driver and has shown success across applications.
In application testing, ANTIFLAME® PCR33 products have demonstrated strong fire performance in a broad range of FR tests:
- Achieves UL94 V-0
- Self extinguishes
- No flaming drips
- Reduced smoke generation
- Formation of a durable, protective char barrier
- Low fogging and low VOC
This balance of performance and practicality is what makes the ANTIFLAME® PCR33 products a compelling choice for formulators looking to modernize their flame retardant systems.
A Practical Path Forward
Whether your priority is improving performance, replacing CPEs and TEPs, or selecting a chemistry that better aligns with your formulation strategy, the ANTIFLAME® PCR33 family offers a solution focused approach to flame retardancy.
