As the core performance guarantee of the polymer processing chain, the functional value of PVC chemical additives is achieving multi-dimensional breakthroughs through the molecular synergy of PVC Lubricant, PVC Stabilizer and PVC Regulator. In the three major application fields of industrial pipes and cable sheaths, medical-grade device components, and food-grade packaging containers, these chemical additives have effectively solved key process bottlenecks such as melt rheology control, thermal degradation inhibition, and micro-phase regulation, becoming an efficiency breakthrough that breaks through the physical limits of traditional PVC materials.
PVC Lubricant optimize processing fluency by reducing the friction coefficient between particles, PVC Stabilizer block decomposition chain reactions with metal soap synergistic systems, and PVC Regulator precisely control the entanglement density of molecular chains. The ternary composite effect not only improves the weather resistance and mechanical strength of the product, but also forms a technical moat at the level of expanded functions such as antibacterial modification and electrostatic dissipation. This provides key material support for the evolution of modern manufacturing towards high precision and customization.
PVC lubricants can reduce friction during extrusion and molding, and prevent defects such as adhesion or surface unevenness. Its main advantages include:
① Improve fluidity and ensure stable product quality.
② Reduce energy consumption by reducing mechanical resistance.
③ Extend equipment life by minimizing wear.
Common types of lubricants include internal lubricants (such as stearic acid) and external lubricants (such as paraffin).
PVC stabilizers can offset degradation caused by high temperature and UV exposure during processing and use. Trend focus:
① Calcium-based stabilizers replace lead-based stabilizers, which is more environmentally friendly.
② Synergistic blends can achieve long-term stability in outdoor applications such as window profiles.
PVC regulators (or chain transfer agents) can adjust polymerization reactions to optimize performance:
① K value control to achieve customized flexibility/rigidity.
② Shorten production cycle through precise molecular weight management.
As sustainable development drives innovation, manufacturers are adopting: bio-based lubricants and non-toxic stabilizers.
Smart regulators for customized PVC grades.
The synergistic effect of PVC lubricants, stabilizers and regulators ensures efficient, durable and environmentally friendly production. As technology advances, these additives will continue to play a key role in meeting global PVC demand.
