What are PVC S65 and S70?
PVC S65 and S70 are common references buyers use when comparing PVC resin grades. The right choice depends on the final application, processing method, equipment, additives and required product performance.
In industrial purchasing, the grade name alone is not enough. Buyers should review the datasheet, COA, producer, packaging, storage conditions, batch consistency and real delivery capability.
Why K-Value matters in PVC resin selection
K-Value helps buyers and production teams evaluate the processing behavior and likely application range of a PVC resin. The more sensitive the process is, the more important it becomes to compare datasheets and previous production experience.
Changing resin grade without testing may affect processability, additive demand, surface quality, flexibility, strength and production stability.
Choosing PVC resin for pipe, profile, cable and flexible products
Pipe, profile, sheet, cable, artificial leather and flexible PVC products may require different resin behavior. The S65 or S70 label should be considered together with formulation, stabilizers, plasticizers, fillers, processing temperature and equipment.
The best buying decision usually involves procurement, production and quality teams defining the application first, then comparing price, stock, documents and delivery conditions.
Documents to check before buying PVC resin
A professional PVC resin purchase should include a datasheet, COA, producer information, packaging details, batch information, storage guidance and transportation requirements. Missing documents increase production and quality risk.
For sensitive production, export or long-term contracts, sampling, production trials and quality approval should happen before large-volume purchasing.
RFQ checklist for buying PVC S65 or S70 in bulk
A useful RFQ should include quantity, target grade, preferred producer, destination, delivery timeline, packaging, invoice requirements, payment terms and required technical documents.
RGG CHEM uses the RFQ workflow for bulk PVC requirements so price, availability, logistics and documents can be reviewed together instead of sending a raw number without context.
