General
The M Series additives represent liquid kickers for PVC foaming.
Typical applications of these kickers are in the manufacturing of car and home upholstery, shoe uppers and plastisol amongst others.
Kickers work in pressure less expansion of PVC pastes by lowering the decomposition temperature of the blowing agent.
Modstab M65, M67 and M68 work as kicker-cum-stabilizer.
The easy dispersibility of these kickers in PVC applications ensures a uniform cellular structure and foam density. The viscosity of the PVC pastes is reduced in most cases.
Properties
All M Series kickers are clear liquids

Storage
These products should be stored in a dry place. The containers must always be kept tightly closed.
Applications
M Series kickers differ in their influence on the rate of decomposition of the blowing agent.
| Kicker | Blow Rate | Process | Remarks |
| Modstab M60 | Fast | Spread Coating | High volume foaming |
| Modstab M62 | Slow | Dip Coating, Rotational Moulding | Contains DOP |
| Modstab M65 | Slow | Coating, Calendaring | Suitable at high temperatures |
| Modstab M67 | Medium | Coating , Calendaring | Excellent for middle coat |
| Modstab M68 | Fast | Calendaring | Bottom and middle coats |
| Modstab M69 | Rapid | Spread Coating | High volume foaming |
| Modstab M70 | Slow | Coating | For long tunnel & low oC |
Dosage
For best results we recommend same amount of kicker as the blowing agent (1:1).
If exceptionally high thermal long-term stability of the PVC compound is required, we recommend the addition of epoxidized oils
Other ratios are offered per the customer request.
