Processing promoters (additives) improve the efficiency of compound mixing and processing, and facilitate complex manufacturing processes.
Processing additives influence the whole production process, from compounding to the finishing of the rubber article.
Reactive extrusion is an attractive route for polymer processing to carry out various reactions, including polymerization, grafting, branching and functionalization. The extruder is like an ideal reactor for polymer chemical modification. Reactive extrusion is an economically attractive process, since the extrusion and processing are done in a single stage.
Read MoreKeltan 13561C was introduced as the premier EPDM grade for extruded seals. It has quickly become apparent that the unique combination of the grade’s characteristics makes this material one of the principal tools for other applications. The very high molecular weight and long chain controlled branching drive economical compounding and enhanced processing. Hose formulations can benefit from these characteristics.
Read MoreCarbon black is commonly used as a filler in rubber and plastic compounds. It is composed of over 90% carbon, with low oxygen and hydrogen content, mainly forming surface functional groups which may participate in polymer reinforcement. Raw almond shells are composed of cellulose, hemicellulose and lignin, representing less than 50% carbon, over 40% oxygen, and at times significant amounts of moisture. The relatively polar nature of almond shells, and their tendency to degrade at processing temperatures, presents a less than ideal alternative when considering fillers for hydrocarbon polymers.
