The technical data sheet (TDS) of China Resources CR-8828 PET material from China Resources corporation, if there are differences, please refer to the official website of China Resources.
Stable Intrinsic Viscosity Range (0.85–0.89 dl/g): Ensures consistent melt fluidity during processing and minimizes uneven wall thickness in finished products.
Low Fines Content (≤ 100 ppm): Reduces fisheyes and black spots, making it suitable for applications requiring high cleanliness.
Superior Color Control (L ≥ 80, b ≤ 1): Delivers uniform product color, low yellowing tendency, and enhanced visual appeal.
Low Moisture Content (≤ 0.2%): Reduces pre-drying load and mitigates the risk of hydrolytic degradation during processing.
Good Chemical Resistance: Resists oils, grease, and most weak acids/alkalis, well-suited for food-contact packaging.
Carbonated Soft Drink (CSD) Bottles: Containers requiring high internal pressure resistance for carbonated soft drinks, sparkling water, and aerated beverages.
Large-Capacity Packaging Containers: 5-gallon water jugs, edible oil bottles, and bulk liquid packaging containers.
Hot-Fill & Food Containers: Condiment bottles, personal care product packaging, and thermoformed ISBM containers.
Blow-Molded Packaging Vessels: Large-capacity bottles and containers for daily chemical or non-food liquid products.
Q1: What are the recommended drying conditions before processing China Resources CR-8828 PET?
A: PET resin is highly hygroscopic, so pre-drying is strongly recommended before processing. The suggested drying temperature is 160–170 °C for 4–6 hours to control the moisture content within processing tolerances, preventing hydrolysis during extrusion/molding and avoiding mechanical property degradation.
Q2: What is the main difference between CR-8828 PET and standard water-bottle grade PET?
A: CR-8828 is a high-viscosity bottle-grade PET (I.V. of 0.85–0.89 dl/g). Compared with standard water-bottle grade PET (I.V. around 0.80 dl/g), it offers higher melt strength and stress-crack resistance, specifically engineered for carbonated beverage bottles and large-capacity containers to prevent bottle swelling and burst. Standard water-bottle grade PET is mainly used for still mineral water bottles.
Q3: Does China Resources CR-8828 PET comply with RoHS standards?
A: Yes, RoHS test reports are available for this grade. It complies with the restriction of hazardous substances mandated by the EU RoHS directive, making it suitable for packaging products exported to the EU market. Corresponding compliance certificates can be requested from your supplier upon purchase.
