Science of Jiaao | The Journey of Plasticizer Exploration
What is a Plasticizer?
Plasticizers are functional additives that, when incorporated into polymers, significantly enhance their flexibility, plasticity, processability, and mechanical properties. They are widely used in PVC, polyurethane, rubber, and other fields.
PVC, with a chlorine content of about 56%, has advantages such as lower petrochemical raw material consumption and reduced CO2 emissions during incineration. This makes PVC products not only cost-effective and highly performant but also significant for resource conservation, sustainable development, environmental protection, and climate change mitigation.
The Principle of Plasticization
Plasticizers weaken the van der Waals forces between polymer molecules, enabling the molecular chains to move more freely. This reduces crystallinity and achieves the plasticizing effect.
Effects of Plasticizers
Key effects include reducing hardness, softening temperature, elastic modulus, and brittle temperature while enhancing flexibility and elongation.
Global Consumption of Plasticizers
Globally, plasticizers are among the most produced and consumed plastic additives, with a production capacity exceeding 8 million tons.
Non-Environmentally Friendly vs. Environmentally Friendly Plasticizers
Plasticizers are classified into two categories based on environmental impact:
Non-Environmentally Friendly Plasticizers:
Common examples: Phthalates such as DOP, DBP; chlorinated compounds like chlorinated paraffin.
Environmentally Friendly Plasticizers:
Petrochemical-based: DOTP (dioctyl terephthalate), DINCH (cyclohexane-based plasticizers), DEHCH.
Bio-based: Epoxidized soybean oil, epoxidized fatty acid esters, citrate esters, and modified vegetable oils.
Hazards of Non-Environmentally Friendly Plasticizers
Health Risks:
Endocrine system disruption (e.g., precocious puberty, hormonal imbalances).
Reproductive system issues (e.g., reduced male fertility, increased risk of female infertility).
Potential carcinogenic risks.
Impacts on the nervous and immune systems.
Environmental Impact:
Pollution and ecological toxicity.
