 “California TB 117: Does The Regulation Add Value?” Matthew Blais, Southwest Research Institute

California TB 117 (CA TB 117) was created to protect life and property from fires initiated by small sources such as matches, cigarettes and lighters. The standard was not intended to prevent ignition of a furnishing in a large fire where it would contribute to the fuel load of a room. To evaluate the effectiveness of the standard, used furniture items and new comparison cushions having various filling components were tested. Both CA TB 117-compliant and non-compliant pieces and equivalent composite mock-ups were evaluated using a small flame ignition source. The paper concludes that the use of CA TB 117 foam increases the safety of home furnishings by delaying the onset of free burning conditions and reducing the total energy released by the event.

 “PTZ: A Troublesome Ingredient; Promising Solutions” John DeMassa, R.T. Vanderbilt

Phenothiazine (PTZ) continues to be an effective scorch inhibitor used by a number of slab-stock foam manufacturers. It has a long successful history as an additive, which is often used in combination with other antioxidants. However, this industrial workhorse comes with an unwanted side effect. Polyurethane foams containing trace quantities of PTZ or its post-reaction derivatives have been observed to occasionally “pink” during warehouse storage. The present paper will examine relevant reaction chemistry; underlying reasons for PTZ induced discoloration and offer some promising new solutions that eliminate “pinking” while providing scorch reduction benefits.

 “New Additives for Polyester and Flame Lamination Foam” Greg Pickrell, Momentive Performance Materials

Momentive has developed a new surfactant for use in flexible polyester slabstock foam applications. Niax L-537XF surfactant is specifically designed to provide finer cells and increased airflow across a wide range of densities. Performance improvements in low-density foams with more stable buns and finer cells are also expected. This new product can be used for conventional polyester foam, semi-rigid and foams with die-cuttable properties. Additionally Momentive is launching a new additive for flame lamination for polyether and polyester applications. Niax CS-26LF is specifically designed to increase the flame bonding properties. The typical range of peeling strength increase in polyether foam is between 20% and 30% when compared to previous generation additives like Niax CS-22LF. This new product also provides mild antioxidant properties and low emission properties. In applications like polyester foam this new product may help increase the initial peeling strength by 40% to 50% when compared to a reference ester foam.

 “New Developments in Flame Retardant Additives For Use In Flexible Polyurethane Foam Products” Mike Nagridge, ICL - IP America

The addition of flame retardants plays a critical role in allowing FPF products to meet flammability performance requirements. Flame retardants must not only perform well in mitigating ignition and combustion, they also must be compatible with FPF production formulation and processing. ICL-IP has developed new flame retardant products to meet the ongoing challenges of today’s market where superior performance in fire tests, foam properties, and scorch is required. Product sustainability continues to be a major criterion for product development. Large scale production evaluations show improvements in flame retardant related properties at low, medium, and high densities. The results of production trial evaluations will be discussed.
