Sinopec PP Y35 is a high-flow polypropylene homopolymer (PPH) fiber grade resin specifically designed for fiber and nonwoven applications. Its uniform molecular structure and relatively high crystallinity enable stable melt flow behavior during fiber spinning processes. The resin performs well in high-speed spinning and spunbond nonwoven production, ensuring efficient manufacturing and consistent product quality.

This material also provides good mechanical strength, low impurity levels, and reliable thermal stability. During continuous production, PP Y35 helps reduce filament breakage and improves operational efficiency. In addition, its high whiteness and uniform pellet quality make it suitable for producing high-quality fiber products.

Key Features

  • Excellent Flowability. PP Y35 has a relatively high melt flow rate (MFR), allowing smooth processing in high-speed fiber spinning and spunbond nonwoven production lines.
  • High Fiber Strength. The resin’s high crystallinity contributes to strong and durable fibers with good tensile properties.
  • Stable Processing Performance. It provides consistent melt behavior during extrusion and spinning, helping maintain stable production and reducing processing fluctuations.
  • Low Odor and High Purity. With low impurity content and minimal odor, Sinopec PP Y35 is suitable for hygiene and medical-related applications.
  • Uniform Pellet Quality. Consistent pellet size and stable batch quality ensure reliable processing and improved manufacturing efficiency.

Typical Applications

  • Nonwoven fabrics (Spunbond, Meltblown, SMS).
  • Medical and healthcare materials such as masks, surgical gowns, and protective clothing.
  • Hygiene products including diapers and sanitary materials.
  • Carpet and industrial fibers.
  • Filtration materials.
  • Agricultural covering fabrics.
