Impact of CaCO3 Fillers in PP-Copolymer (Compounding Costs Rs 10/Kg.)
Like in the past article, estimations on the impact of Filler stacking on Compound cost and Volume costs are done in Table 1 below. This is a hypothetical exercise, as filler loadings of more than 60-70% are hard to accomplish. The CaCO3 filler loadings have been extended to discover what is the impact on volume expenses and reach inferences.
It is fascinating to take note of that despite the fact that these are hypothetical computations, the anticipated thickness is very close to the really estimated thickness with the distinction being a couple of focuses in the third decimal place. Once in a while do we discover mistakes in the second decimal place. There is some thickness increment because of unstable misfortune, however this is very low in Polyolefins, and I expect the Filler isn’t wet.
The graphical portrayal of the counts are appeared in Chart 2,
Explaination of CaCO3 filled PP Copolymer and its cost reduction effection.
- Assuming that Rs 10 a Kg is the Compounding cost, at a level of approx 15% filler does the cost of Compound plunge beneath the crude PPCO value (Rs 90/Kg). At the point when the business edges of the compounder is incorporated, it is just at the 20-25% Filler level that the Purchase cost of a Filled PPCo compound will come beneath base polymer cost.
- The rate of diminishing of Volume Cost is a considerable measure slower, and just at half Filler levels, the Volume cost decreases to the base polymer level.
- This implies for all shaped (or Extruded PP Products which are sold per piece (i.e. by volume), acquired filled PP Compounds (ordinarily 10-40% filler) won’t bring down expenses. They should just be utilized for esteem expansion like better firmness, paintability and so on. This is an extremely clearing articulation and is by all accounts borne out practically speaking.
There is an approach to limit the impact of the moderately high Compounding and change costs.
