DÜSSELDORF, Germany -- Vertellus is showcasing Citroflex® bio-based plasticizers at K 2016. Citroflex plasticizers are compatible with hydrophilic and lipophilic polymers. They allow the formulator to obtain performance parameters not available with individual plasticizers.

To help customers address increasing public demand and toughening regulatory requirements regarding material safety and sustainability, Vertellus is spotlighting here at K 2016 (hall 5, stand C08-2) its ZeMac® copolymers and Citroflex® bio-based plasticizers.

Citroflex Plasticizers - Safe for Food-contact and Medical Applications

  • Compatible with a wide range of hydrophilic and lipophilic polymers and polymer blends.
  • Also compatible with several non-citrate plasticizers.
  • Plasticizers for medical grade PVC.
  • A suitable replacement for di-2-ethylhexyl adipate (DEHA) for food contact applications.
  • Providing an alternate for DEHA where there has been some concern for the public health. 
  • Citroflex A-4, A-6, and B-6 versus DEHA and di-2-ethylhexyl phthalate (DEHP) as the sole plasticizers for medical grade PVC.

“The plastics industry faces growing pressure to demonstrate that it is part of the solution – not the problem – for better safety and sustainability,” said Ashok Adur, Ph.D., global commercial development director, Plastics at Vertellus. “We help our customers respond by offering targeted additives to meet challenges, ranging from reducing raw materials and energy consumption to protecting consumer health. Adding to their value, our products can also help customers increase profits and differentiate their materials from competitors. These solutions are a key part of Vertellus’ active participation in the American Chemistry Council's Responsible Care® initiative.”

Supporting Environmental Efforts

The United States alone accounts for 5.35 billion pounds of PET plastic a year, less than a third of which is recycled, according to the National Association for PET Container Resources.1 ZeMac powders and masterbatches – including a new line of masterbatches launched here today – promote greater use of post-consumer and post-industrial PET and other resins by improving their performance and processability. By incorporating up to 40 percent recycled resin with virgin polymer, compounders can cut costs while helping to reduce raw material use and avoid landfilling.

At cost-effective low loadings, ZeMac copolymers raise a recycled resin’s performance properties, including flexural modulus and strength, tensile strength and elongation, impact resistance and heat deflection temperature (HDT). They can be used with PA, PET, TPU, polybutylene terephthalate (PBT), polycarbonate (PC), polyoxymethylene (POM) and biopolymers.

Vertellus additives also improve compounding and processing of recycled materials. For example, ZeMac® E60-P powder and new ZeMac® Extend P62 masterbatch compatibilize PA and recycled PET, which are normally incompatible, to reduce material costs and increase profits. The new ZeMac® Extend L65 masterbatch raises the viscosity of recycled PA to make it suitable for injection molding. In blow molding and profile and film extrusion applications, the new ZeMac® Extend L68 masterbatch ensures even distribution of the additive to produce smooth, uniform surfaces with no gels.

Other areas where ZeMac provides sustainability include temperature control and energy conservation. Here, ZeMac® E400 powder and ZeMac® Solution S407015 and S403520 water-based grades are used for the microencapsulation (surrounding very tiny droplets or particles of liquid or solid material with a continuous film of polymeric material) of phase-change materials. This technology has applications in maintaining mattress and clothing temperature for comfort and building insulation to support green building initiatives.

Providing Safer Options

Increasing restrictions are being placed on the use of phthalate-based plasticizers. For example, in December 2014 the U.S. Environmental Protection Agency issued a Significant New Use Rule under the Toxic Substances Control Act for DnPP, a phthalate used in polyvinylchloride (PVC) plastics shown to cause developmental and/or reproductive effects in laboratory animals.

To avoid the use of traditional phthalates, many manufacturers are turning to iso-phthalates and bio-based plasticizers. Vertellus’ Citroflex bio-based plasticizers are manufactured without the use of phthalates and have proven their safety in food-contact and medical applications. As a leading plasticizer on the market today derived from bio-based citric acid, Citroflex products offer a non-toxic, biodegradable option for biopolymers and specialty polyvinyl chloride (PVC) used in food packaging, medical applications, childrens’ toys and coatings.

Vertellus technology experts are on hand at the company’s booth for the duration of K 2016 to answer questions and provide additional details about the company’s full line of innovative additives for the plastics and polymer industries.
