Masterbatch (MB) is a solid or liquid additive for plastic used for coloringplastics (color masterbatch) or imparting other properties to plastics (additive masterbatch). Masterbatch is a concentrated mixture of pigments and/or additives encapsulated during a heat process into a carrier resin which is then cooled and cut into a granular shape. Masterbatch allows the processor to colour raw polymer economically during the plastics manufacturing process.
The alternatives to using masterbatches are buying a fully compounded material (which may be more expensive and less open to e.g. color variability of the product), or compounding from raw materials on site (which is prone to issues with achieving full dispersion of the colorants and additives, and prone to preparing more material than what is used for the production run).
As masterbatches are already premixed compositions, their use alleviates the issues with the additive or colorant clumping or insufficient dispersion. The concentration of the additive in the masterbatch is much higher than in the end-use polymer, but the additive is already properly dispersed in the host resin. In a way their use is similar to uses of ferroalloys for adding alloying elements to steels.
The use of masterbatches allows the factory to keep stock of fewer grades of the polymer, and to buy cheaper natural polymer in bulk.
Sarsoli Industrial Company Limited is a master batches, fillers and additives manufacturing unit based in Amuwo Odofin, Lagos, Nigeria. We started production from February 2011. The company has 8 twin-extruders and 3 Kneader Lines. Testing machines and a full fledge lab with up-to-date lab equipments.
The manufacturing set up is constructed in a 40,000 square feet area in a 1.5 acre land. It consists of:
a) A large production area.
b) Office building.
c) Raw materials and finished goods store.
d) Generator Room.
e) Driver and security cabins.
f) Staff toilets and shower rooms.
g) Parking lots etc.
This project is been led by very experienced board of directors who have more than 30 years of experience in manufacturing field and Nigerian working conditions. One of the Nigerian board members is a renowned solicitor. Sarsoli Industrial Company Ltd. is the first of its kind in Nigeria. The large production capacity, the challenges of new technological advancements and being the first ones in this industry are bold steps that we have taken. We have been successful in producing high quality products. We are not only making Black, White and Colour masterbatches efficiently but we are also making Fillers for Flexible packaging, Sack and Chair industries. Also, recently we have been successful in developing additives that are required by the plastic factories.
Many of the plastic product manufacturers have shifted from imported to locally produced products by “Sarsoli”. These master batches are well accepted in the market and used in all the plastic industries to produce different coloured finished products like chairs, tables, household items, woven sacks, flexible packaging etc.
