Polymer Glossary
| Abraded | Worn away by friction |
| Abrasion | Worn away |
| Ambient Cure | Cure occurs at room temperature |
| ANSI | American National Standards Institute |
| ASME | American Society of Mechanical Engineers |
| ASTM | American Society for Testing and Materials |
| Catalyst | Ingredient in polyurethane which initiates a chemical reaction or increases the rate of chemical reaction |
| Chalking | Powdery surface condition due to disintegration of surface binder from weathering |
| Cure | Process which completes the chemical reaction |
| Compression Load Deflection (CLD) | A measure of firmness |
| Density | Weight per unit volume, (lbs/ft3) (pcf). Density is not related to pore size, firmness, stiffness or load bearing capacity |
| Elastomeric | Polymers which resist and recover from deformation produced by force |
| EPDM | Ethylene Propylene Diamine Monomer is a high density rubber |
| Extruded | Forced through die of tubing machine in either solid or hollow cross section and becomes a continuously formed piece |
| Fatigue | Measure of the loss in load bearing capability |
| Indentation Force Deflection (IFD) | Measure of load bearing capacity (firmness or stiffness) |
| ISO | International Organization for Standardization |
| Isocyanate | Chemical compounds having one or more NCO (Nitrogen, Carbon, Oxygen) groups attached to the main chemical chain |
| Open Cell Structure | Permeable structure in flexible foam where there is no barrier between cells, and gases or liquids can pass through the foam |
| PolyGreen™ | RPM's brand name for a superior polymer made with recycled materials |
| Polymer | A macromolecular material formed by the chemical combination of monomers having either the same or different chemical composition |
| Polymer Density | Density of the material made up strictly by the foam chemistry without fillers or reinforcements included |
| Polymerization | Converts monomers into polymers |
| Rubber | General term for elastomer materials |
| Viscosity | Flow property of a material. The lower the number, the thinner the liquid |
| Vulcanized | A a solid elastomer produced by crosslinking a liquid suspension of polymer molecules |
