Product description
Saika PVC SG‑5 is a suspension PVC resin with K‑value around 67 designed for rigid and general‑purpose applications. It offers a balanced combination of processing stability, mechanical strength and surface quality in extrusion and injection processes.
The resin is suitable for UPVC pipe, fittings, profiles and sheets, as well as selected cable and compounding applications where stable viscosity and low gel count are required. Each batch is supplied with a certificate of analysis confirming key parameters such as K‑value, viscosity number, impurity level and volatile content.
Key advantages
- Standard SG‑5 K≈67 grade for a wide range of rigid PVC applications.
- Low volatile matter and moisture content to support stable extrusion and injection.
- Controlled impurity and grain distribution to help achieve clean surfaces and low gel levels.
- Consistent apparent density and flow for reliable mixing and conveying behaviour.
- Supplied with detailed COA and inspection report for each production batch.
Typical applications
- UPVC pipes and non‑pressure sewer pipes.
- Fittings and couplings for drainage and electrical conduit systems.
- Rigid profiles and technical sections.
- Sheets and boards for construction and packaging.
- Selected cable and compounding applications (depending on formulation design).
