Product Characteristics of Yisheng PET Resin

1. High Transparency & Excellent Appearance

Yisheng PET resin is produced from high-purity raw materials using highly controlled polymerization technology, resulting in crystal-clear transparency, a low b-value, and superior surface gloss. It is especially suitable for applications requiring premium appearance and clarity.

2. Low Acetaldehyde Content

The resin has strictly controlled AA levels to minimize odor and taste impacts on filled beverages or food products. This makes it suitable for mineral water, juice, tea drinks, and flavored beverages.

3. Superior Processing Performance

Yisheng PET demonstrates stable melt flow behavior and good thermal stability. It performs well in injection molding, extrusion, and stretch blow molding, ensuring uniform preform production, high molding efficiency, and reliable performance on high-speed equipment.

4. Low Moisture & Good Dimensional Stability

The resin has low moisture absorption and a controlled carboxyl end-group content (–COOH), which enhances hydrolysis resistance, improves mechanical properties, and ensures dimensional stability of final products.

5. Low Impurities & High Cleanliness

With low ash content, minimal black spots, and low heavy-metal residuals, Yisheng PET resin reduces surface defects such as silver streaks, haze, and bubbles, contributing to excellent optical quality.
