Frequently Asked Questions (FAQs)
Q1: Is drying required for PVC S-700 before processing?
A1: Although PVC S-700 is a suspension resin and is relatively less sensitive to moisture, it is recommended to perform hot-air pre-drying at 60–80°C during humid seasons or if storage conditions are poor, to eliminate potential steam bubbles during high-temperature processing.
Q2: What is the difference between PVC S-700 and other PVC grades with different degrees of polymerization (e.g., S-1000)?
A2: PVC S-700 has a relatively lower degree of polymerization, offering better flowability, which makes it more suitable for extrusion molding processes that require high production efficiency. Higher polymerization grades like S-1000 typically exhibit greater mechanical strength and are suited for applications requiring high toughness.
Q3: Does this material comply with international environmental standards like RoHS and REACH?
A3: The production of Qilu Petrochemical PVC S-700 complies with national and industry environmental requirements. For customers exporting to the EU or other regions, it is recommended to contact the sales team directly to obtain the latest RoHS and REACH test reports to confirm that the batch meets the latest restricted substance regulations.
