Use characteristics: The curing tetarder predispersion CTP-80 retards the onsetof cure in NR and diene sythetic rubbr without considerably extending the total curing time. It is preferably used with sulphenamide or thiazole accelerators to improve processing safety, keeping the properities of the vulcanizate unchanged. Predispersion CTP-80 significantly improves the storage stability of uncured diene rubber compounds. When predispersion CTP-80 is used in the compounds, it is possible to process the rubber compounds at higher temperatures, thereby ensuring full use of machine capacity. Contact staining does not occur. Predispersion CTP-80 causes only very slight discolouration in bright or white articles.
Processing advantages: The thermoplastic, excellent compatible EPDM/EVA binder which is combined with active dispersing promoters allows much more easily and quickly incorporation and excellent dispersion in the rubber mixing. In this way, optimal activity of the effective CTP is assured.
Dosage levels: Normally 0.2-2.0 phr
Applications: Compounds based on synthetic diene rubber and natural rubber,which are mainly cured with thiazole and sulphenamide accelerators(e.g. in the production of tires, conveyor belts, soles, technical mouldled and extruded articles).
Storage stability: In original closed containers under cool and dry conditions max.2 years)
