APPLICATIONS
FYNOL-40 IN PVC PLASTISOLS:
Reduces the viscosity of plastisol formulations, when added in optimum proportions.
The effects demonstrated are
:
* For a given shear rate, viscosity is reduced by up to 50% at low
shear rates and up to 33% at higher shear rates.
* When stored for periods of up
to 21 days, low viscosity is retained.
FYNOL-40 does not have adverse effects on the mechanical properties of cured plastisols and in some circumstances impro
ve them. Since FYNOL-40 is in liquid form at formulation temperature, its incorporation in plastisol formulations is very easy.
There are additional beneficial effects in using FYNOL-40 viscosity depressants
. FYNOL-40 can be used as a post-polymerization additive in E-PVC manufacture, it has also useful antistatic
properties.
FYNOL-40 AS A VISCOSITY DEPRESSANT FOR PVC LEATHERCLOTH: FYNOL-40 is an effective viscosity depressant for PVC Plastisol.
For manufacturing PVC leathercloth by spread coating technique, use of FYNOL-40
gives following advantages.
* It helps in dispersion of pigments and fillers, thus enables better surface finish and gloss.In white (TiO2) leather cloth, remarkable improvement in colour strength (whiteness) is observed using Fynol-40
* Enables uniform coating
* Reduces pin-holes and improves mechanical properties
* Give uniform cell structure
* Finish and feel gets improved
* Facilitates release of air from PVC paste

USE LEVEL
recommended is about 5 to 10% of total
plasticizers level depending upon the
viscosity and stiffness desired.
USE IN PVC PASTES
An addition of FYNOL-40 to the level of 1% related to PVC + Plasticizer facilitates the
release of air in PVC pastes. At the same ti
me a reduction in viscosity is noticeable. The
use of FYNOL-40 in PVC pastes ensure block free
and slipping surfaces
to the moulded toys /
parts etc.
ANTISTATIC AGENT:
FYNOL-40 is used as an internal antistatic agent for soft PVC products. It is homogeneously incorporated into the soft PVC compound at the compounding stage. Due to its hydrophilic characteristics, it imparts antistatic properties to the soft PVC compounds. It is particularly effective in medium to high plasticized compounds.
