Extrusion is a fundamental process in manufacturing a vast array of PVC products, from pipes and profiles to films and sheets. The efficiency and quality of this process are heavily influenced by the properties of the PVC compound and the additives used. Among these, processing aids are paramount for ensuring smooth extrusion, high output, and excellent surface finish. NINGBO INNO PHARMCHEM CO.,LTD., as a dedicated manufacturer and supplier of specialty chemicals, offers advanced PVC processing aids that are vital for achieving superior results in extrusion applications.

Challenges in PVC Extrusion

PVC, while versatile, presents specific challenges during extrusion that can impact both the process and the product:

  • Melt Fracture: This occurs when the PVC melt is forced through a die at a certain speed, causing the flow to break and leading to a rough or uneven surface on the extruded product.
  • Die Build-up: The tendency of PVC to adhere to the metal surfaces of extruder dies can cause dimensional inconsistencies and surface defects.
  • Inadequate Melt Strength: A PVC melt lacking sufficient strength can sag or deform after exiting the die, especially in larger profiles or films, leading to dimensional instability.
  • Poor Heat Stability: PVC can degrade if exposed to excessive heat or shear during extrusion, resulting in discoloration and a loss of mechanical properties.

Addressing these issues requires additives that can modify the rheological properties of the PVC melt and improve its interaction with processing equipment.

How Our PVC Processing Aids Enhance Extrusion

Our range of multi-functional processing aids, primarily based on acrylic copolymers, is meticulously designed to optimize PVC extrusion. They achieve this by:

  • Promoting Fast and Homogeneous Fusion: By accelerating the fusion process, these aids ensure that the PVC particles melt and merge into a uniform, stable melt. This homogeneity is key to smooth flow through the die.
  • Increasing Melt Strength and Elasticity: This directly combats issues like melt fracture and sag, allowing for the production of complex profiles and thin films with excellent dimensional accuracy. When you buy our processing aids, you are investing in improved structural integrity.
  • Providing Lubrication: They create a release layer between the PVC melt and the metal surfaces of the extruder, significantly reducing friction, preventing die build-up, and minimizing adhesion. This leads to cleaner runs and less downtime.
  • Improving Surface Finish: The outcome of better melt homogeneity and reduced defects is a smoother, often glossier surface finish on the extruded product.

Applications in Extrusion

These benefits are crucial for a wide range of extrusion applications. Manufacturers producing PVC profiles for windows and doors, pipes for construction, sheets for various industries, and films for packaging all benefit significantly from the enhanced stability and quality provided by our processing aids. As a supplier, we ensure our products are compatible with standard extrusion grades and can be easily integrated into existing formulations.
