Main Characteristics

Exceptional Transparency & Premium Appearance. Yisheng PET resin uses high-purity raw materials and precisely controlled polymerization technology to deliver outstanding optical clarity. The resin features a low b* value and high surface gloss, creating a crystal-clear, premium appearance. It is an ideal choice for applications that demand superior transparency and visual appeal.
Ultra-Low Acetaldehyde Content. Yisheng strictly controls acetaldehyde (AA) levels to minimize odor and taste transfer to packaged contents. This ensures excellent sensory performance and makes the resin well suited for mineral water, juices, tea-based beverages, and flavored drinks.
Excellent Processing Performance. The resin offers stable melt flow behavior and excellent thermal stability. It runs smoothly in injection molding, extrusion, and stretch blow molding processes, supporting consistent preform quality, high production efficiency, and reliable performance on high-speed production lines.
Low Moisture Absorption & Outstanding Dimensional Stability. With low moisture absorption and optimized carboxyl end-group (–COOH) control, Yisheng PET resin resists hydrolysis effectively while enhancing mechanical strength. These characteristics ensure excellent dimensional stability in finished products.
High Cleanliness & Low Impurity Levels. Yisheng PET resin maintains low ash content, minimal black specks, and extremely low heavy-metal residues. This high level of cleanliness reduces surface defects such as silver streaks, haze, and bubbles, resulting in superior optical quality and consistent product performance.
