For B2B professionals in the plastics industry, optimizing manufacturing processes is a constant pursuit. Enhancing extrusion efficiency, reducing defects, and increasing output are key objectives. Chlorinated Polyethylene (CPE) 135A plays a crucial role in achieving these goals when used as a processing aid for PVC. NINGBO INNO PHARMCHEM CO.,LTD., as a dedicated chemical supplier, highlights how this versatile additive can revolutionize your PVC production.

PVC, while a versatile material, can sometimes present processing challenges such as melt fracture, die build-up, and poor melt elasticity. These issues can lead to surface imperfections, reduced throughput, and increased scrap rates. CPE 135A addresses these concerns effectively by modifying the rheological properties of the PVC melt during processing.

How CPE 135A Functions as a Processing Aid:

  • Elimination of Melt Fracture: Melt fracture, characterized by a rough, uneven surface on extruded profiles, occurs when the polymer melt is subjected to high shear rates in the die. CPE 135A, when incorporated into the PVC formulation, helps to lubricate the polymer melt and reduce internal friction. This allows the melt to flow more smoothly through the die, preventing the elastic turbulence that causes melt fracture. For manufacturers aiming to buy high-quality profiles with smooth surfaces, CPE 135A is a valuable addition.
  • Reduction of Die Build-up: Another common processing issue is the accumulation of polymer residue on the extruder die. This build-up can lead to inconsistencies in product dimensions and eventually necessitate line shutdowns for cleaning. CPE 135A's chemical properties help to minimize the adhesion of PVC melt to the metal surfaces of the die, thus reducing the rate of build-up and extending production runs.
  • Improved Melt Strength and Elasticity: CPE 135A contributes to a more cohesive and stable melt. This improved melt strength is particularly beneficial in processes like blown film extrusion or profile extrusion, where the molten material needs to maintain its shape and integrity as it exits the die. It also aids in reducing extrusion pressure, lowering energy consumption.
  • Enhanced Plasticization: As a processing aid, CPE 135A can influence the plasticization process of PVC. It can help to achieve faster and more uniform plasticization, ensuring that the PVC particles are properly fused and integrated into a homogeneous melt. This leads to better overall material properties and a more efficient processing cycle.

Benefits for Manufacturers Buying CPE 135A:

By incorporating CPE 135A as a processing aid, manufacturers can expect:

  • Increased Output: Smoother processing and reduced defects allow for higher line speeds and greater productivity.
  • Improved Surface Finish: The elimination of melt fracture results in smoother, more aesthetically pleasing surfaces on extruded products.
  • Reduced Scrap Rates: Better melt control and fewer processing issues mean less material waste.
  • Lower Energy Consumption: Reduced extrusion pressures and improved melt flow contribute to energy savings.
  • Cost-Effectiveness: The combined benefits of increased efficiency, reduced waste, and extended equipment life make CPE 135A a cost-effective solution for optimizing PVC production.
