PETG Resin For 3D Printing Filaments

PETG Resin WS-502 — Technical Datasheet (Industrial Grade Polyester Resin)

1. Product Description

WS-502 is a high-performance PETG thermoplastic polyester resin designed for industrial processing applications including PETG shrink sleeve labels, 3D printing filament, sheets, plates, bottles, and molded containers.

It provides a balanced combination of high transparency, strong impact resistance, low processing temperature, and stable shrink performance, making it a practical replacement for PVC and conventional PET materials.

The material is suitable for industries requiring both optical clarity and mechanical toughness, especially in packaging, labeling, and additive manufacturing.

Typical application fields include:

Medical and pharmaceutical packaging
Food-grade containers and packaging
Daily-use consumer products
Industrial thermoformed sheets and molded parts
