 “Non-Contact In-Process Foam Dimension Measurement” Daryl Rutt, RangeMetrics

Current practice for determining processed foam dimensions typically relies on QA lab measurements of sample pieces. Modern requirements for lower missed defect rate along with the increasing implementation of MRP/ERP systems in foam plants makes 100% in-process measurement a desirable and cost-beneficial addition to foam manufacturing. A measurement method based on a laser line / rangecamera technique previously developed by RangeMetrics has been successfully implemented in a number of foam plants to capture closely-spaced dimensions of the top and side surfaces of hot or cold slabstock buns. The technique is non-contacting and measurements are collected in real time as a bun passes past the laser / rangecamera, for example on a pouring line or on a transfer conveyor in the cold shop. However, measurements of different dimensional variables at different points in the foam fabricating process lead to a variety of different requirements and a variety of technical challenges which are discussed in the paper.

 “Combustible Dust Regulatory Update” Brian Edwards, Conversion Technology, Inc.

Combustible dust presents a significant hazard to industrial facilities, and it is at the forefront of regulators’ agendas, especially the U.S. Occupational Safety and Health Administration (OSHA). OSHA enacted a National Emphasis Program (NEP) in 2008, and the agency is conducting inspections under this program. OSHA has issued an Advanced Notice of Proposed Rulemaking (ANPR), and is working to develop a specific combustible dust rule. This paper will discuss the characteristics of combustible dust, current regulations and standards, anticipated regulatory initiatives, and how facilities should address combustible dust safety.

 “Versatile High Renewable Content Based Polyol for the Production of Multiple Flexible Slabstock Foam Technologies” William Gower, Cargill Biobased Polyurethanes

This paper will describe the development and evaluation of a new BiOH Polyol designed for the production of multiple TDI based flexible slabstock foam technologies such as: low density CO2 foaming; solids free load building capability; high resiliency, viscoelastic, and traditional trough foams.

 “PLX 982: A New Liquid Scorch Inhibitor” John DeMassa, R.T. Vanderbilt Company

The present paper explores a new scorch inhibitor blend that reduces scorch significantly when compared with state-of-the-art products and adds minimally to foam discoloration when exposed to selected stresses such as light or NOx fumes. A short discussion will also be offered on the mechanism of thermo-oxidative degradation and inhibitor stabilization of PUR foam.
