How to formulate PVC Compounds

A discussion started in 2001 and continuing through 2017 . . .


Q. How to make PVC Cable Compound for AVSS automotive cable.

Rakesh Jain
- Delhi, India


A. Rakesh,

Any manufacturer (but not necessarily a supplier) of PVC resins should surely be able to help you and tell what 'additives' are needed for your cable compound ... so that all you'd have to do was to mix the PVC resin (Banbury type mixer?) with those ingredients to come up with a suitable and flexible compound.

Further, any competent extruder of PVC (profiles, pipe etc) would or should also know the answer.

Hope this helps!

A. Rakesh,

Start from the following formulation:

PVC S-70 or higher 100 phr
DIDP 40 "
Powder NBR 20 "
Stabilizer 6 "
Calcined Kaolin 10 "
Stearic Acid 1 "

I wait to hear you how this formulation works.

Hi Sisira., Most people will disbelieve that you'd pick a business to go into where you "have no idea" how to make the product :-)

We sympathize that you may be having a language difficulty in getting your idea across, but please try your best to describe in detail what you are presently doing, and in what ways it doesn't meet your needs because whole books must be read to gain the general idea of how to make such products. Thanks!

Hi Junai. Unfortunately, Sisira's posting received no responses at all in 3 years, and there is no reason to expect that just repeating it without adding a word of your own will gain a better result. Sorry, but best of luck.

PVC thin profile formulation

February 22, 2017

Q. dear experts

I m going to enter PVC profile extrusion field as a new entrepreneur. I'm concerned about the formulation of PVC wall panels. I want to use up to 70% calcium carbonate, does it make sense? can I use as much high level of filler in the formulation of thin wall PVC profiles?

Any answer would be appreciated.
