Predispersed Rubber Chemicals MB-80
Category : Catalyst and Auxiliary/Rubber Auxiliary Agent
CAS NO : EC NO : MF : MW : Packing : 25 kg Product description : Detailed Product Description Manufacturer experienced,Stable , continuable,environmental ISO9001,ISO14001,REACH pre-register.Powder,Granular,Masterbatch HiDispersion Predispersed Rubber Chemicals MB-80 Non-staining antioxidant for vulcanizates based on natural and synthetic rubbers Product description Composition 80%2-mercaptobenzimidazole 20% EPDM/EVA binder and dispersing agents Appearance White-grey granules Density,20 oC Approx. ~ 1.27 g/cm3 (20oC) Physiological properties : See safety data sheet (MSDS) Raw material characteristics of MBT: Melting point ~ 290 oC Evaporation loss ≤ 0.5 % MBT content ≥ 98% Ash content ≤ 0.5 % Use Characteristics HiDispersion MB-80 is a non-staining antioxidant for light-coloured and white rubber compounds. It is used as a synergist for other antioxidants. The effect of the combination of HiDispersion MB-80 with other antioxidants is greater than the sum of the effects of the individual components. The combination of HiDispersion MB-80 with antiozonant IPPD is suitable for extremely heat resistant vulcanizates. It also provides the vulcanizates with some protection against copper and manganese poisoning. The efficiency of HiDispersion MB-80, used on its own, depends to a large extent on the curing system. HiDispersion MB-80 gives better results in combination with dithiocarbamate and thiuram accelerators than in combination with other accelerators. 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 MB is assured. Dosage levels As antioxidant: 0.6 - 1.5 phr As antioxidant, specially for steam-resistant grades: 2.0 - 3.0 phr for transparent grades: 0.4 phr. Applications Rubber articles which must withstand oxygen, heat and steam; heat-resistant rubber articles which are produced by thiuram vulcanization; white, coloured and transparent articles of all kinds; fabric proofings. Packing Net 25 kg cartons with plastic inner. Storage stability In original closed containers under cool and dry conditions max. 2 years. Handling Consult material safety data sheet (MSDS) for additional handling information. Uses : rubber products Synonyms : no data
