The second mechanism is through chemical compatibility of the substrate and the overmolding TPE compound. Chemical compatibility depends on the surface energies which are related to the cohesive density match between the substrate and the TPE.

Extensive compatibility testing confirmed that the new grades would bond chemically with the engineering thermoplastic rigid substrate required in the device.

Sustainability Spotlight Hydrocerol™ Chemical Foaming Agents Reflection electron microscopy (REM) view of foamed plastic Hydrocerol Chemical Foaming Agents are supplied as concentrates CHEMICAL FOAMING AGENTS (CFAs) are chemical substances that react under the influence of heat to release gas into the plastic matrix during the manufacturing process of plastic parts. They can also be part of the chemical foaming process, achieving a material expansion of up to 50%. Up to 30% weight reduction can be achieved with Hydrocerol Chemical Foaming Agents in these applications.

HOW IT WORKS Excelite additives typically contain 70%wt of active chemical foaming agent (CFA), dispersed in a liquid carrier, thus promoting greater product efficiency. The carrier system is selected for optimal compatibility with the polymer network and the use of dispersants helps the CFA particles efficiently mix and disperse within the extrusion process. Consistency of surface both chemically and physically leads to more even wetting of the ink which ensures good dot definition—the key to higher quality digital print images.
