Granular Blends, as suggested by name, consist of a mixture of several additives blended
together in compact granules. The use of Granular Blends by one hand provides all the
advantages already seen for PREMIX, by the other hand allows to add in the mixing the
whole or the main part of additives in one step. 

The Granular Blends are usually projected and manufactured on customer recipe:

• RDC chooses the right polymeric support and the active part concentration
• RDC manufactures the Granular Blends in very mild conditions
• RDC tests the relative stability of the recipe formulation in order to check an eventual degradation process and the shelf life of the blend
• The automatic control of weight of any component during the process and the final quality control in laboratory, gurantees concentration levels

RDC is able to supply perfectly homogeneus powder blends, produced on customer demand. The production is carried out under strict control of relative concentration of the components and process condition in order to avoid degradation effect. The blends are supplied in 20Kg net multi-ply paper bags, or, on specific request, in handy predosed and preweighed low temperature melt bags.

BENEFITS

• Warehouse rationalisation
• Reduced and clean handling of raw materials
• Lower costs for packing disposals
• Reduced risks and environmental impact
• Compound uniformity
• Possibility to pack up in customer’s required gram-weight

PREWHEIGHING
The preweighing is one of the more appreciated RDC service.
RDC can supply in predosed and preweighed low melting temperature bags, the entire range of chemical auxilliares produced and/or distributed, including aromatic amines (IPPD, 6PPD, DTPD, ODPA), mixture of aformentioned auxiliaries and liquids (silanes, low molecular polybutadiene, etc…).
The “bag-in-bag” predosing is preferred when RDC tests, show that, the contact between one or more components should give chemical instability of the blends, or also when the customer would like to look at the number of components. Each bag, comprising one or more additivies, is then put together and sealed in one larger bag.

As well as its own exclusive formulations, RDC distributes most of the chemical auxiliaries used in the rubber and thermoplastic industries. RDC guarantees and certifies the quality of all its additivies thanks to the strict analytical controls carried out by RDC Chemical Laboratory.
