PETG Resin WS-502 For Sheet

WS-502 has the characteristics of high transparency, low haze, good mechanical properties, and low processing temperature compared to ordinary polyester.

WS-502 is a high-performance PETG resin developed for PETG shrink sleeve labels, 3D printing filaments, sheets, films, bottles, and container applications.

As a transparent thermoplastic polyester material, WS-502 provides excellent optical clarity, impact resistance, flexibility, and stable shrink performance. Compared with conventional PVC and standard PET materials, it offers improved processing flexibility and lower molding temperature requirements.

This PETG resin is designed for applications requiring high transparency, durability, and easy processing, including packaging, labeling, medical containers, food packaging, daily-use products, and additive manufacturing materials.

WS-502 can be processed into various sheets, plates, bottles, and containers where high transparency, toughness, and molding efficiency are required.
