Equipped with core instruments including gas chromatographs, intrinsic viscosity testers, calorimeters (DSC), and microscopes, our 24/7 operational systems accurately capture key parameters, providing a solid hardware foundation for PETG production and quality inspection.
We implement a fully closed-loop testing protocol covering raw material inspection, in-process polymerization monitoring, and finished film re-inspection. Rigorous checks at each stage ensure every batch meets specifications.
We enforce stringent control over PETG pellet quality by testing core parameters such as melting point, intrinsic viscosity, carboxyl end groups, and color values. This guarantees stability for subsequent melt processing and film extrusion.
Utilizing French-made SCANTECH thickness gauge for 24-hour online monitoring of heat-shrinkable film thickness, and complemented by German Mahr mechanical thickness gauges, high-precision water baths, tensile testers, and hazemeters, we perform real-time tracking of thickness, heat shrinkage, tensile strength, haze, and other critical indicators. This ensures superior film quality that meets high-end application requirements.
Adopting stringent industry benchmarks and customized internal testing specifications with exacting precision requirements, we ensure consistent, compliant performance across diverse application fields.
