Rigid PVC products for Construction, engineering, and other industrial applications require high mechanical strength, dimensional stability, impact resistance, and long-term durability. In general, SG-5 is suitable for most rigid products, while SG-7 and SG-8 are recommended for applications demanding higher levels of hardness and pressure resistance. Rigid products typically do not require plasticizers, however, a minor dosage of ESBO can be added to improve processability when desired.
Key applications in this segment include pipes, sheets, fittings, panels, profiles, flooring, roofing & wall cladding.
The following sections present recommendations on resin grades for key application areas, reflecting practical formulation insights and the performance criteria demanded by specific product requirements.
1.Pipes, Fittings & Engineering Components
water supply pipes, drainage pipes, electrical conduits & pipe fittings
Recommended PVC Resin: SG-5 (general), SG-7 (high-rigidity), SG-8 (extreme rigidity & pressure resistant)
2.Building Profiles & Structural Materials
door&window frames, fencing profiles, decking boards, railings & structural profiles
Recommended PVC Resin: SG-5 (general), SG-7 (high rigidity)
3.Panels, Boards & Decorative Materials
wall panels, ceiling panels, decorative boards, foam boards & rigid wall cladding
Recommended PVC Resin: SG-5 (general), SG-7 (high rigidity), SG-8 (extreme rigidity & pressure resistant)
4.Sheets & Roofing Materials
rigid sheets, transparent sheets, roofing & corrugated sheets
Recommended PVC Resin: SG-5
