Sub, Substitute or Rubber Substitute
Factice is the vulcanized fatty oil (vegetable
oil or, in some cases ,animal oil). Such oils are reacted with sulfur（Brown
Factice) or sulfur monochloride(White Factice). Also sulfur and chloride
free factice is available which is produced by the reaction of peroxide and
isocyanate with fatty oil.
You can use it in your rubber compounds as a
processing aid, softener, dry plasticizer and also to prevent the
shrinkage and to improve the fluidity of the compounds.
< three major features which
are not in other processing aids>
melting at about 200℃,
the form and dimensions of the compounds are
held and also to be prevented from shrinkage.
mobility of the compound is improved by the
lubricant effect of distributed factice
particles, also the extrusion condition and the
molding speed are improved.
3. Due to
the oil absorptive capacity, factice prevents
bleeding of other liquid ingredients in the
rubber compound and also prevents the tacky
surface of the cured compound.
<Applications and features of factice>
1. Improves process ability and shortens mixing
2. Increases speed of extrusion and reduces die
smooth surface and good appearance of the
4. Improves process-ability of grinding of the
cured rubber such as roll application.
5. Reduces calendar grain and prevents shrinkage of
6. Prevents the sag of the compound and gives
stable dimension of the compound.
7. Improves mold flow and mold release and results
in less waste.
8. Prevents the blooming and improves oil and
the flexibility of the compound.
Improves aging properties.
Decreases tackiness of the compound and lessens
to generate heat in the process.
Decrease cost per volume.
<Examples of the use>
rubber hose, rubber tube, rubber vibration
insulator, rubber roll/ blanket / board / packings / wire
cover, sponge rubber, gum tape, automotive
weather strip / door sealing / window flame,
foot wears, rubber gloves, soft tennis ball,
eraser, lubricant additives, cleaners.
