PVC formulation

PVC is a very popular material in numerous sectors, mainly due to its versatility, which makes it ideal for obtaining products with a wide range of properties, and its performance-processability-cost ratio.

The main sector where PVC is used is the building industry, with the most typical products being profiles, piping, vinyl flooring and WPC decking, wire coatings, blinds, etc.

However, international regulations are restricting the use of some of the additives used in PCV, which affected the product health conditions and his recycling feasibility.

Currently, sustainability is the most important trend in PVC. Using recycled materials and additives or resins from renewable sources will be key to the future of this material.

Our solutions to optimise PVC formulations

We offer customized, innovative solutions to the entire value chain, from resin producers to compounders, processors and end users, in the following areas:<

  • Development of both rigid and flexible customized formulations.
  • Introduction of recycled materials and assessment of processing. Maximum recycling intake studies.
  • Selection of the most suitable additive system, depending on the final properties and applications required, processing technology and applicable legislation.
  • Comparative studies of multiple additive behaviours at lab scale (stabilizers, lubricants, processing aids, etc.) using a torque rheometer.
  • Lab scale and pilot plant scale trials using new additives to test their effectiveness and viability.

Technical advice and assistance

AIMPLAS has worked on different projects involving rigid, flexible and plastisol PVC, using new plasticizers, stabilizers, waxes, lubricants, nanometric fillers, etc. This expertise has allowed us to develop new compounds and adapt PVC to new standards to use new additives.

We can assist you in the following areas:

  • Formulation in co-rotating and counter-rotating twin-screw extrusion and internal mixer (Plasti-Corder) or roller mixers.
  • Dynamic stability studies using a Plasti-Corder to adjust thermal stabilization.
  • Gelation studies to detect mechanical failures.
  • Optimization of the dry-blend process.
  • Direct extrusion from sheets and profiles (one-step compounding + extrusion of final products).
  • Direct customer assistance at the company’s facilities, assessment and audit of PVC-related processes.
  • Personalized training on formulation design (fillers and additives selection) and processing.
