Quality versus quantity: How changes in EPDM polymer impact molding
EPDM is a widely used polymer for many molded goods, as it is inherently water, ozone, UV and weather resistant, and generally recommended for temperatures ranging from -50°C to 150°C. EPDM can be a low cost material option, as it allows for high total loading and has a low specific gravity, yielding low pound-volume cost. EPDM responds well at various process temperatures, and is used in many applications, such as seals, gaskets, weather resistant parts, NSF 61 water potable applications, FDA applications, roofing components, electrical resistant compounds, and more

Modification of fluoroelastomers based on TFE-P copolymer to improve cure speed, physical properties and mold release
This article presents research conducted to develop modified TFE-P that improves curability and mold release, and provides good amine resistance and compression set. It is demonstrated that a cure site monomer can easily be copolymerized into the TFE-P backbone to solve the abovementioned performance problems, while maintaining original TFE-P characteristics of resistance to heat, steam, and organic and inorganic acids and bases. In addition, it is possible to color the material

Achieving savings in the post-curing process of fluoroelastomer compounds prepared by injection molding
Commonly, rubber compounds based on FKM elastomers are subjected to two stages of cure in order to optimize physical and mechanical properties. Compression set and tensile strength are the main properties usually improved by the post-cure stage. The initial stage is called curing, and is performed under pressure in a mold during the injection molding process. A secondary stage called post-cure is performed in an oven under air or nitrogen atmosphere in order to complete crosslinking reactions. This removes volatile by-products and additives to obtain enhanced, stable physical and mechanical properties
