Medical, toy, food, and other high-safety PVC products have stringent requirements for safety & biocompatibility, sterilization resistance, low migration, low odor, and chemical inertness. Selecting the right PVC resin and plasticizer ensures product quality while fully complying with regulatory requirements.
Key applications in this segment include medical equipment (e.g. infusion bags & tubes, blood transfusion bags, medical gloves), children’s toys, food wrapping films & containers, and indoor sports flooring.
The following sections present recommendations on resin grades and plasticizers for key application areas, reflecting practical formulation insights and the performance criteria demanded by specific product requirements.
1.Medical Infusion Bags, Blood Transfusion Bags, Infusion Tubes
Recommended Plasticizer:
Conventional: DOP - high plasticizing efficiency, excellent compatibility with PVC, non-reactive with pharmaceutical solutions and blood, cost-effective
Phthalate-free Alternative: DOCH - hydrogenated derivative of DOP, phthalate- & benzene-free, similar plasticizing efficiency & PVC compatibility as DOP, non-reactive with pharmaceutical solutions and blood
Auxiliary Stabilizer & Plasticizer: ESBO - mainly as auxiliary heat stabilizer for cost efficiency
Recommended PVC Resins: SG-5 (general), SG-3 (high flexibility)
For matte-finish products, please refer to PVC Matting Resin SG-5 and PVC Resin Matting SG-3.
2. Medical Gloves
Recommended Plasticizer:
Conventional: DOTP - phthalate-free, environmentally-friendly, high plasticizing efficiency, excellent compatibility with PVC paste resin, cost-effective
Advanced Alternative: DOCH - hydrogenated derivative of DOP, phthalate- & benzene-free, similar plasticizing efficiency & PVC compatibility as DOP, higher safety level
Auxiliary Stabilizer & Plasticizer: ESBO - mainly as auxiliary heat stabilizer for cost efficiency
Recommended PVC Resins: SG-5 (general), SG-3 (high flexibility)
For matte-finish products, please refer to PVC Matting Resin SG-5 and PVC Resin Matting SG-3.
3.Children’s Toys
Recommended Plasticizer:
Primary Plasticizer: DINCH - hydrogenated derivative of DINP, phthalate- & benzene-free, low migration
Auxiliary Stabilizer & Plasticizer: ESBO - mainly as auxiliary heat stabilizer for cost efficiency
Recommended PVC Resins: SG-3 (general), SG-5 (higher hardness, e.g. toy cars), DP-1800 (high elasticity, e.g. inflatable toys)
For matte-finish products, please refer to PVC Matting Resin SG-5 and PVC Resin Matting SG-3.
4.Food Wrapping Films, Containers
Recommended Plasticizer:
Conventional: DOCH, DINCH - hydrogenated derivative of DOP and DINP, phthalate- & benzene-free, high plasticizing efficiency, low migration, low exudation
Cold Resistant Alternative: DOA - phthalate-free, outstanding low temperature softness, low viscosity, good compatibility with PVC
Auxiliary Stabilizer & Plasticizer: ESBO - mainly as auxiliary heat stabilizer for cost efficiency
Recommended PVC Resin: SG-5 (general), SG-3 (high flexibility), DP-1800 (high elasticity)
For matte-finish products, please refer to PVC Matting Resin SG-5 and PVC Resin Matting SG-3.
