Replacements for Discontinued Albemarle Products Antiblaze RX-35 and BK-69

Two new flame retardants to replace discontinued Albemarle products are now available from Cellular Technology:

CELLTECH® FR-35RX Flame Retardant is a functional replacement for Antiblaze RX-35, and is a combination of synergistic bromine/chlorine and phosphorus-containing  active ingredients. CELLTECH FR-35RX is recommended for UL-94 HF-1 applications.

CELLTECH® FR-69BK Flame Retardant is an exact equivalent to the discontinued Antiblaze BK-69. The identical composition of CELLTECH FR-69BK offers a simple replacement option for foam producers who can not longer get Antiblaze BK-69 but who have designed formulations specifically around this unique FR. 

Cellular Technology International adds product equivalent to Albemarle’s NcendeX P30…

In response to customer demand for a replacement product to match Albemarle’s recently withdrawn NcendeX P30, Cellular Technology International is now offering CELLTECH FR-2416, a non-halogenated flame retardant plasticizer identical to NcendeX P30. Like the NcendeX P30, CELLTECH FR-2416 finds broad application in polyurethanes, vinyls, epoxy resins and engineering thermoplastics such as polycarbonate/ABS and mPPO.

CELLTECH FR-2416 is fully commercially available, in drums, totes and bulk shipments. For more information, please contact us at +1 678-766-0430 or

Flame retardant plasticizers for PU and vinyl

Cellular Technology International, and our European subsidiary Cellular Technology Europe Ltd have added a broad range of flame retardant plasticizers to our product offerings, with wide application for polyurethane and vinyl.

The CELLTECH IPPP product range is a family of isopropylated phenyl phosphates, identical to the widely used REOFOS line. We offer the product grades IPPP-35, IPPP-50, IPPP-65 and IPPP-95 which are equivalent respectively to REOFOS 35, 50, 65 and 95. Isopropylated phenyl phosphates are used as flame retardant plasticizers in flexible polyurethane foam and in vinyl applications such as mine belting, and vinyl sheeting. 

CELLTECH HF-4 and HF-4L are tert-butylated phenyl phosphates also recommended for polymer applications such as polyurethane and vinyl, and also are widely used as functional hydraulic fluids. CELLTECH HF-4 is equivalent to REOFOS 507,  PHOSFLEX 71B and SANTICIZER 154; CELLTECH HF-4L is a low-TPP content version of HF-4, equivalent to PHOSFLEX 71B Plus.

All of the above products are available in drums, IBCs (totes) and bulk deliveries. For more information, contact us by email at

CELLTECH FR-60i, a replacement flame retardant for TDCP (“TDCPP”, “chlorinated tris”)

On the heels of California’s October 2011 decision to place the widely used PU flame retardant TDCP on its Proposition 65 list of cancer-causing chemicals (see , many PU producers have taken steps to to replace the product with safer alternatives. TDCP is also known as “TDCPP”, “chlorinated Tris”, and under such trade names as ANTIBLAZE 195, ANTIBLAZE WR-30-LV, FYROL FR-2, FYROL FR-38, FYROL A-300-TB, CP-2 and others.

An excellent alternative to TDCP is CELLTECH FR-60i, an environmentally and toxicologically safer chlorinated phosphate ester which compares well performance-wise to TDCP, but carries no Proposition 65 labeling. In composition, CELLTECH FR-60i (10.4% phosphorus, 35.8% chlorine content) compares favorably to TDCP (7.2% phosphorus, 49.1% chlorine content) and can be substituted for  TDCP at equal or slightly reduced use levels in most flexible PU formulations.  CELLTECH FR-60i produces flexible polyether and polyester PU foams with excellent physical properties and reduced scorch as compared to TDCP. It is also the product of choice where low emissions and low fogging are required.
