In their early years Chlorinated Parafin acquired a reputation for poor colour and low thermal stability. However, by employing modern chlorination techniques and the use of straight-chainliquid parafin feedstocks, chlorinated products are now produced which are water-white and have proporties comparable to those of the octyl phthalates.

Chlorinated Parafin can be used as sole plastisizers in relatively hard products, such as flooring compounds, but they are more normally used as partial replacements for phatalate or phosphate primary plastisizers. Since they are avilable at lower prices than primary plastisizers, their use in PVC compounds gives significant savings in raw metarial csts. The proporties of finished compounds are not impaired and flame retardance may be improved when Chlorinated Parafin is includedin viniyl composition.

The use of chlorinated parffin secondery plastisizers is straightforward and provided that the compatibility limits are not exceeded, no exudation occurs.
