Predispersed rubber chemicals and their uses

Rubber accelerators or accelerants are chemicals used to speed up the rubber manufacturing process (vulcanisation). This objective is to make untreated natural rubber latex suitable for manufacturing several rubber products.

Aside from the sulfur itself, sulfur bearing compounds that liberate sulfur at the vulcanization temperature can be used as vulcanizing agents. These are called sulfur donors. They are used to generate a network capable of resistance to degradation on exposure to heat. The main advantage of sulfur donors is that they reduce the normal blooming of sulfur in unvulcanized compounds.

Use of retarders in a variety of situations makes them a critical component of a rubber compounder’s toolbox of rubber technology. The most common use of retarders is to give a marginally processing stock some more scorch time. This might involve increasing the flow time in a mold or allowing a calendar to be run at a higher temperature for making a calendared sheet smooth.

Metal oxides are crystalline solids that contain a metal cation and an oxide anion. They typically react with water to form bases or with acids to form salts. The most important basic oxides are magnesium oxide (MgO), a good thermal conductor and electrical insulator that is used in firebrick and thermal insulation, and calcium oxide (CaO), also called quicklime or lime, used extensively in manufacturing and in water purification. The use of Magnesium Oxides in the rubber industry is very important to many halogenated and non-halogenated elastomers.

Granular blends 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.

Dry liquids are required to avoid the problematic dosage of liquid additives. Advanced technologies allow homogeneous absorptions of any liquids, even the more viscous ones. The carrier consists in an inert silicate with high specific surface in order to minimize the wet effect and to increase the flowability. Dry liquids consists of unique blends of highly-absorbent amorphous silicas. These provide solutions to the problems of quickly incorporating high volumes of liquids within a compound without affecting the physical properties of the final vulcanisation.

Organic colour pigments masterbatches for polymers mass colouring are concentrates that transform thermoplastic and thermoset polymers from colourless and opaque materials to coloured. There are soluble colorant substances (dyes) and insoluble substances (pigments) that can be organic or inorganic, natural or synthetic. Combinations of these types of ingredients are contained in the modern masterbatches along with other non-colouring additives. It is through this complexity that it is possible to develop strength, depth, and resistance to colours.
