Yisheng PET YS-Y01 Oil Bottle grade

PET YS-Y01 is a high-viscosity, oil bottle grade polyethylene terephthalate resin developed by Hainan Yisheng Petrochemical Co., Ltd. It is designed for blow molding of oil bottles, chemical containers, transparent packaging sheets, and other industrial packaging applications. Yisheng YS-Y01 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.

Melting Point (DSC)	°C	248 ± 2	Stable melting behavior for precise molding control
Acetaldehyde (AA)	µg/g	≤ 1.0	Very low; ensures neutral odor and safe food contact
Carboxyl End Group (COOH)	mmol/kg	≤ 35	Low terminal acid content; enhances thermal stability
DEG Content	wt %	1.2 ± 0.2	Contributes to balanced flexibility and clarity
Moisture Content	wt %	≤ 0.4	Requires proper drying before processing
Ash Content	wt %	≤ 0.08	Ensures high purity and good surface finish
L Value (Brightness)	—	≥ 80	High transparency and brightness
b Value (Yellowness)	—	≤ 2.0	Very low yellowness for clean, clear appearance
Density	g/cm³	1.39 ± 0.01	Typical for crystalline PET resin

Compared with common bottle grade YS-W01, 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 of PET YS-Y01

High Intrinsic Viscosity (0.83 dl/g). YS-Y01 PET provides excellent mechanical strength, toughness, and durability — 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. PET 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

Processing Recommendations

To achieve optimal performance and maintain the resin’s quality, follow these processing guidelines:

Drying

PET is hygroscopic; proper drying before processing is essential.
Recommended: Dry at 160–180 °C for 4–6 hours until moisture ≤ 0.02%.
Use a dehumidifying dryer to prevent hydrolysis and viscosity degradation.

Melt Processing

Typical melt temperature: 270–285 °C.
Mold temperature: 20–40 °C.
Avoid prolonged residence time or overheating to prevent yellowing or IV loss.

Acetaldehyde Control

Maintain short residence time and avoid oxidation to preserve low AA levels.
Color/Transparency Control
Prevent contamination, dust, and degraded material to ensure a low b value and high L value.

Regrind Usage

Although regrind may be used, it can affect color tone, IV stability, and mechanical performance. Recommended ratio ≤ 10%.

Compatibility Check

For hot-fill, carbonated, or reheat stretch-blow applications, confirm suitability before use (these processes may require specialized grades such as YS-H01 or YS-C01).
