  • Which plasticizers are the most important commercially?
  • This is why external plasticizers are the most important commercially. External plasticizers can be monomeric or polymeric. Examples for polymeric plasticizers are EVA, CPE, NBR and terpolymers or polyesters mainly based on adipic acid, diols and mono alcohols.
  • What does purinova do?
  • Purinova is a manufacturer and supplier of polyester polyols and polyurethane systems. It offers rigid foams, surfactants, esters, polymeric plasticizers, and more. The company’s products find applications in construction, refrigeration, and automotive industries. Purinova has 5 employees across 5 locations.
  • What are the different types of plasticizers?
  • There are two main groups of plasticizers: Internal plasticizers are part of the PVC molecule (where a second monomer is copolymerized into the polymer structure). Internal plasticizers have generally too narrow of a temperature processing range to be useful. This is why external plasticizers are the most important commercially.
  • What are plasticizers used for?
  • Plasticizers are the major functional additives transforming the physical properties of polymers such as PVC, PU, acrylic, nitrile and rubbers to create a whole world of flexible and durable finished articles for high demanding applications. The world plasticizer consumption was around 7.82 million MT in 2017, up nearly 25% over 6 years .
  • What are the different types of external plasticizers?
  • External plasticizers can be monomeric or polymeric. Examples for polymeric plasticizers are EVA, CPE, NBR and terpolymers or polyesters mainly based on adipic acid, diols and mono alcohols. Examples for monomeric plasticizers include phthalates, adipates, benzoates, and citrates. They can be further divided into:
  • Do plasticizers need to be compatible with PVC?
  • First and most important, they need to be compatible and permanent to stay durably in the final article. Plasticizers also need to withstand heat and shear during processing and sustain severe aging conditions. Mixing plasticizers with PVC and processing the blend need to be cost-effective as well.
