PLASTICIZER FOR COAL TAR PITCH / TAPE MADE FROM COAL TAR PITCH
Why is COPLAST 4 (Plasticiser for Coal Tar Pitch / Tapes made from Coal Tar Pitch) needed?
- To impart plasticity without affecting penetration number.
- To provide better heat and solvent resistance
- Helps in achieving petroleum insolubility.
In market there are many kind of plasticizers are available based on wax/wax derivatives. COPLAST 4 (Plasticiser for Coal Tar Pitch / Tapes made from Coal Tar Pitch) is unique plasticizer which is not wax/wax derivative that C.G. Chemical manufactures.
COPLAST 4 (Plasticiser for Coal Tar Pitch / Tapes made from Coal Tar Pitch) is not wax/wax derivative. COPLAST 4 (Plasticiser for Coal Tar Pitch / Tapes made from Coal Tar Pitch) is compatible with most materials used in Coal Tar Industry.
COPLAST 4 (Plasticiser for Coal Tar Pitch / Tapes made from Coal Tar Pitch) is proprietary polymer.
COPLAST-4 (Plasticiser for Coal Tar Pitch / Tapes made from Coal Tar Pitch) has unique heat, water & solvent resistance. This when added as plasticizer along with coal tar material does not lower ring & ball softening point of coal tar material. At the same time it improves Needle Penetration from about 1 * 10-1 mm to about 5 * 10-1 mm.
COPLAST 4 (Plasticiser for Coal Tar Pitch / Tapes made from Coal Tar Pitch) has specific properties as below,
| Chemical Nature | Proprietary polymer |
