JC-880 PVC Processing Aid for PVC Extruded Profiles
PVC profile processing additives effectively enhance the mechanical properties, processability, and thermal/cold resistance of PVC products, exhibiting a synergistic reinforcing effect with inorganic fillers. Practical application data indicates that their addition improves tensile strength and elongation at break by 1-3 percentage points while significantly reducing drop weight impact failure rates. The powder exhibits excellent flowability, preventing bridging during mixing. It also reduces raw material costs by partially replacing resin, with a maximum addition rate of 25 parts (recommended 1-5 parts). Testing confirms the product enhances surface gloss and brightness of PVC profiles, improves dimensional stability, elevates Vicat softening temperature by up to 3°C, and optimizes heat shrinkage from -1.8% to -1.6%. It demonstrates strong process adaptability, reducing production costs by 150-260 RMB per ton while maintaining physical properties compliant with GB/T 8814 standards.
PVC Profile Processing Additive (JC-880) is a functional additive specifically designed to enhance the performance of PVC profiles. It is a white powdered organic compound packaged in 25kg composite woven plastic bags. Custom packaging is available. Primarily used in building materials such as profiles and pipes, this product exhibits excellent compatibility with PVC resin and can be directly added during the compounding process without altering the original formulation ratios.
