How Next-Generation Plasticizers Achieve Sustainability & Flexibility

Plasticizers are additives that are included in polymers to improve their flexibility, endurance, and processability. They reduce the attraction between polymer chains, allowing the chains to move more freely which makes the material more flexible and elastic. Yet, rising inspection of the environmental and health impacts has motivated researchers and industry leaders to look for safer – and – more efficient alternatives. Manufacturers alter the polymer’s physical properties and aim to achieve softness, elongation, and resistance to cracking.

Flexidone as a Substitute for Phthalates

Phthalate plasticizers—like di-2-ethyl hexyl phthalate, diisononyl phthalate, and diisodecyl phthalate—have long dominated the global plasticizers market. But with growing awareness of their health risks, the industry has shifted towards safer alternatives, including Flexidone plasticizers. Derived from N-alkyl pyrrolidone chemistry, Flexidones deliver improved performance and processability over traditional options. Curious about how plasticizers work and their different types? Discover more in our in-depth guide on plasticizer types and applications.

Key benefits of Flexidone include:

Cold Temperature Flexibility: Provides flexibility even at temperatures as low as -70°C.
Low Volatility and Migration: Reduces emissions and retains stability at high temperatures.
Broad Applications: Suitable for industries like flooring, automotive wiring, and more.

Flexidones are 30-50% more efficient than standard phthalates like DINP, making them a cost-effective choice in flexible PVC systems. Blends with secondary plasticizers have demonstrated compatibility and performance enhancement. REACH-compliant Flexidone products are available globally, supporting safer, eco-friendly applications.

The Hallstar Company’s recent acquisition of an ester manufacturing facility from Lanxess further strengthens the supply of phthalate-free plasticizers. Their new benzoate and citrate ester lines meet consumer & regulatory demands for safer plasticizers, especially for sensitive applications like food packaging and children’s toys.

Bio-based plasticizers reduce carbon footprint

Bio-based plasticizers are sustainable alternatives derived from renewable sources like vegetable oils. By reducing dependence on fossil fuels they significantly lower the carbon footprint of plastic production. These non-toxic plasticizers also meet stringent safety standards, addressing consumer demand for eco-friendly products.

Some key benefits of bio-based plasticizers:

Environmental Impact: Lower carbon footprint compared to conventional plasticizers.
Economic Support: Supports farmers and rural communities by utilizing agricultural resources.
Innovation Catalyst: Encourages the development of new formulations tailored to sustainability.

A notable example, Pevalen™ Pro 100, offers an approximately 80% reduction in carbon footprint compared to its fossil-based counterparts. Lanxess also launched a renewable and phthalate-free plasticizer, adipic acid dihydrazide-2-ethylhexyl ester, in August 2023, positioning it as a more eco-friendly choice.

In June 2023, the KLJ Group invested $145 million in a new facility in Gujarat, which will produce 50,000 tons of phthalic anhydride and 100,000 tons of plasticizer annually, highlighting the scale of investment in sustainable plasticizers

Thermal stability and low volatility increase endurance

For applications involving extreme heat thermal stability in plasticizers is crucial. Products that uphold properties under high temperatures are ideal for automotive interiors, electronics and industrial products – building consumer trust in reliability and performance.

Key advantages include:

Durability: Trimellitate plasticizers are ideal for high-temperature environments, including automotive interiors.
Industry Commitment: In 2022, Arkema partnered with Ecolab to develop high-performance plasticizers with an emphasis on thermal stability.

Low-volatility plasticizers further improve safety by reducing emissions during production & use. This design choice addresses environmental & regulatory demands for safer products and helps manufacturers sustain product quality without compromising safety In 2021, the acquisition of NatureWorks by Clariant emphasized the importance of low-volatility eco-friendly plasticizers in their offerings.
