Yisheng PET YS-Y01 is a high-viscosity, oil bottle grade polyethylene terephthalate resin. This grade is mainly designed for blow molding of oil bottles, chemical containers, transparent packaging sheets, and other industrial packaging applications. YS-Y01 PET resin features excellent clarity, superior mechanical strength, low acetaldehyde (AA) content, and high resistance to oil and chemicals. It is produced using 100% virgin PET raw materials, ensuring product purity, stable viscosity, and consistent performance.

Compared with common bottle grade YS-W01, Yisheng YS-Y01 PET resin has a slightly higher intrinsic viscosity (IV), providing better strength and chemical durability — ideal for oil, lubricant, or chemical packaging applications.

Product Features

  • High Intrinsic Viscosity (0.83 dl/g). PET YS-Y01 provides excellent mechanical strength, toughness, and durability, making it ideal for thick-wall bottles and containers.
  • Outstanding Clarity and Color Stability. Excellent color tone with low yellowness index and high brightness, ensuring a clean appearance of finished products.
  • Low Acetaldehyde (AA) Level. AA ≤ 1 µg/g ensures neutral odor and taste, suitable for food or edible oil packaging applications.
  • Superior Oil and Chemical Resistance. Excellent resistance to oil, grease, mild alkalis, and many organic solvents, ensuring long-term performance for chemical or lubricant packaging.
  • Excellent Processability. Stable melt viscosity and consistent performance make it suitable for both injection preform molding and blow molding operations.
  • High Mechanical Strength and Surface Hardness. Yisheng YS-Y01 demonstrates high rigidity, creep resistance, and surface hardness, approaching that of thermosetting plastics.
  • 100% Virgin Material. Manufactured from virgin monomers, free of recycled PET contamination, ensuring consistent optical and mechanical properties.

Typical Applications

Yisheng PET YS-Y01 resin can be widely used in packaging and industrial applications that demand clarity, strength, and chemical resistance, including:

  • Lubricant and Engine Oil Bottles
  • Household Chemical Containers
  • Industrial Chemical Packaging Bottles
  • Transparent Sheets and Thermoformed Trays
  • Food and Daily-Chemical Product Packaging
  • General Blow-Molded or Injection-Molded Containers
