White Factice for Colored Rubber Products

White Factice powder – vulcanized vegetable oil for rubber compounding, available from Lab Line Enterprises
Product Overview

White Factice is a high-quality vulcanized vegetable oil product (sulphur-chloride style). It is used as a processing aid, plasticizer/extender, and surface modifier in rubber compounding. Its creamy-white colour and stable properties make it ideal for white or pastel coloured compounds, erasers, light-coloured rubber mouldings and applications where low discolouration is required.

Key Benefits
  • Colour stability: Suitable for white or light-coloured rubber compounds with minimal discoloration.

  • Improved processing: Enhances incorporation of fillers, improves milling and extrusion behaviour.

  • Plasticizer / oil absorption: Absorbs and retains plasticizers well, reducing migration and surface blooming.

  • Dimensional stability and green strength: Helps maintain shape during pre-cure / cold handling; reduces die swell.

  • Surface finish and feel: Provides a smooth, velvety or supple finish in final rubber goods.

  • Reduced cure distortion / shrinkage: Helps in moulded/extruded parts to maintain shape, less warpage.

Applications
  • Rubber erasers

  • White or pastel coloured rubber mouldings

  • Light coloured extrusions / hose / seals

  • Open-steam cured rubber parts where heat or discolouration may be a factor

  • Used in natural rubber (NR), styrene-butadiene rubber (SBR), chloroprene rubber (CR), and other elastomers where white or light colour is needed

Recommended Dosage
  • Typical usage range: 5 to 30 phr (parts per hundred rubber), depending on desired effects (plasticizing, softness, finish) and rubber formulation.

  • For white grade sulphur-chloride factice, small amounts of acid acceptors (e.g. MgO) or accelerator adjustments may help offset cure retardation.

Disclaimer: Always check compatibility, processing conditions and perform small-scale trial before full-scale use. Published dosage recommendations are for guidance only.
