Innovative Additives Are a Boon for the Processing of High-filled PVC.

PVC is one of the five general plastics, with excellent comprehensive performance and high cost-effective advantages, is widely used in all walks of life. With the increasingly fierce market competition, high-fill modification has become an effective cost-cutting efficiency scheme. However, high filling can negatively affect the processing of PVC materials and the performance of the final product, including:

1. Plasticization slows down, resulting in production efficiency;

2. Melt strength decreased, difficult to process;

3. Small molecular matter is easy to analyze during processing;

4. Processing torque is too large, resulting in equipment damage;

5. Product comprehensive mechanical performance is poor;

6. Multi-layer composite product spoff strength decreased.

The result of these negative effects is a lower product pass rate and an increase in customer complaints. The calculation may also find that the overall cost has not decreased, and the original intention of reducing cost efficiency has not been realized.

There is no very effective solution to such problems in the industry. For example, the general internal and external lubricants, can not shorten the plasticization time, some will even extend the plasticization, and there is a great risk of destructing; Therefore, the mechanical improvement of high-fill material is limited.

To this end, Bick Chemical has introduced an innovative processing aid, DISPERPLAST-1180. Designed for the processing of high-fill thermoplastic PVC, this high-efficiency wetting dispersal aid has low volatile properties and is solvent-free. The processing improvements it brings include:

1. Plasticization speed up, melting index increased significantly, and thus improve production efficiency;

2. The melt viscosity decreases, and the thermal stress of the melt decreases.

3. Processing torque reduction, more energy-saving, equipment loss is smaller;

4. Better melt distribution, higher melt strength;

5. Under the specified process conditions, the higher filler content.

Improvements to the final high-fill product include:

1. Material toughness is enhanced, thus improving the impact resistance of the product;

2. Break elongation increased, anti-bending stiffness decreased;

3. The plasticizer content in the product is reduced;

4. The surface is smoother (higher gloss), thus improving the lamination performance;

5. Allow smaller or thicker fillers, thereby reducing the cost of the formula.
