PVC Formulation

Despite some polemics regarding the use of PVC, this material is still highly used in multiple sectors. This is mainly due to its versatility to obtain products with very high range of properties (from highly rigid, like pipes, to highly flexible like leatherette) and to the ratio performance/processability/cost, which makes it almost impossible to replace by other plastics. Currently, the PVC market is oriented to the building area, for the elaboration of profiles, piping, vinyl flooring and WPC decking, wire coating, blinds, etc.

However, due to the European regulation REACH (nº 19097/2006 (CE), approved on December 18th 2006, and implemented from June 1st 2007), the use of some PVC additives has been limited, affecting the production of the final product as well as the possibility of recycling existing products.

Our Solutions

To optimize PVC formulations and to get ahead new regulations, we offer solutions to PVC (and its additives) users and producers based on these guidelines:

  • Design of formulations for specific applications.
  • Selection of most suitable additive system, according to: final properties and applications, processing technology, applicable legislation.
  • Comparative studies of multiple additives behavior at lab scales (stabilizer, lubricants, processing aids, etc.) using a torque rheometer.
  • Lab scale and pilot plant scale trials using new additives to test its viability.
  • Weight reduction (density) by means of formulation modifications.
  • Study and optimization of processability of any PVC formulation.
  • Substitution of fillers and additives if necessary.

Technical Support

Product of 15 years of compounding trials, AIMPLAS has acquired good experience in the development of research projects working with PVC, which has allow us to define working protocols for the optimization of PVC formulations and the introduction of new additives and fillers. This way we have been able to develop new compounds or adapt PVC to new regulations by the use of new additives. AIMPLAS has develop different projects in the scope of rigid, flexible and semi-rigid, using new plasticizers, waxes, lubricants, nanometric fillers, etc.

We can help you through our following capacities:

  • Effective mixing in planetary, co-rotating and counter-rotating TSE, and roller mixer.
  • Compounding trials using very small amounts of materials to test new, rare or expensive additives.
  • Use of turbomixers to obtain dryblends, and high-speed mixers to obtain plastisols.
  • Possibility to do direct extrusion into sheets and profiles (one step compounding + extrusion).
  • Direct assistance at company’s facilities.
  • Personalized training on formulation design (fillers and additives selection) and processing.
