Introduction
In polymer processing, plasticizers play an indispensable role. These additives penetrate between polymer chains, reducing intermolecular forces and transforming rigid materials into products with enhanced flexibility, elasticity, and processability.
Plasticizers not only improve manufacturing efficiency but also influence the final product’s tactile feel, durability, and safety. Choosing the right plasticizer requires careful evaluation based on application needs, regulatory compliance, and processing conditions.
How Plasticizers Work
Plasticizers diffuse into polymer chains and reduce the attraction between molecules. This allows originally rigid materials to become soft, elastic, and easier to process.
Common Applications
- PVC products: flooring, wires, toys
- Medical devices: tubing, gloves
- Food packaging films
- Automotive interior materials
Regulatory Compliance Matters
Plasticizer selection must consider not only performance but also regulatory safety. Traditional plasticizers such as DEHP, DBP, and DINP have been listed as SVHC (Substances of Very High Concern) or toxic chemicals due to reproductive toxicity or environmental risks.
According to EU REACH regulations, if a product contains SVHCs above 0.1%, disclosure and risk assessment are required. Taiwan’s EPA also lists several plasticizers as toxic substances, requiring registration and control.
For applications involving food contact materials, toys, or medical devices, stricter limits apply. Products must comply with standards such as FDA, EN71, and CNS.
Technical Tips
- Confirm the intended use and contact targets (e.g., food, medical, children’s products)
- Pay attention to dosage and processing methods (e.g., coating, dipping, plastisol)
- Regularly check for regulatory updates (REACH, RoHS, FDA, etc.)
