Key Notes

1.  Processing & Welding Guidelines:

       Hot Air Welding: Temperature should be controlled between 250-350°C with even speed to ensure complete fusion of the welding rod and base material.

       High-Frequency (RF) Welding: Suitable for PVC containing polar plasticizers, resulting in strong and aesthetically pleasing seams.

       Bonding: Use PVC-specific adhesives (e.g., cyclohexanone solution or polyurethane glue). Surfaces must be cleaned and activated.

2.  Selection & Usage Recommendations:

       Outdoor or High-Temperature Environments:** Choose weather-resistant and heat-resistant formulations (with low-migration plasticizers) to prevent hardening, embrittlement, or plasticizer exudation.

       Contact with Food or Human Body:** Always select non-toxic formulations compliant with relevant regulations (e.g., medical grade, food grade).

       Dimensional Stability:** For products with strict dimensional requirements, fabric-backed composite sheets or low-shrinkage formulations are recommended.
