The Paradigm Shift in Concrete Shuttering Engineering
Transitioning from consumable timber plywood to high-density polymer matrices: Lowering total construction expenditure while satisfying global decarbonization imperatives.
Polymer Micro-Foaming Science
Modern polymer shuttering boards utilize advanced Polyvinyl Chloride (PVC) and Polypropylene (PP) co-extrusion technology. By introducing nano-scale nucleating agents during melt processing, China factories form a high-density micro-cellular core shielded by ultra-smooth non-porous outer skins.
50+ Reuse Cycle Horizon
Unlike traditional film-faced plywood that swells, delaminates, and degrades after 3 to 5 reuses due to moisture absorption, structural PVC/PP plastic formwork panels achieve 30 to over 80 concrete pours without shape deformation or structural degradation.
Zero Release Agent Requirement
The chemical inertness and ultra-low surface energy of rigid PVC and hollow PP panels prevent wet concrete from bonding. Demolding requires no toxic oil-based release agents, leaving a glass-smooth mirror finish that eliminates secondary plastering costs.
China PVC Plastic Formwork Supply Ecosystem
Why procurement teams at global construction firms partner with specialized manufacturers located in Jiangsu’s industrial polymer hubs.
Shuyang Polymer Cluster Density
Located in Shuyang County, Suqian City, Jiangsu Province, Greenstar New Materials Shuyang Co., Ltd. operates within China’s premier composite and synthetic material cluster. This proximity grants instant access to premium virgin PVC resin, calcium-zinc stabilizers, and UV inhibitors, driving unmatched cost efficiencies and formula purity.
Advanced Extrusion Lines & 3,000㎡ R&D
Equipped with 8 automated twin-screw co-extrusion production lines and a dedicated 3,000㎡ R&D test laboratory, our facilities ensure strict dimensional tolerance control (±0.3mm), uniform rib structure in hollow PP panels, and optimized flexural modulus suited for heavy hydraulic concrete pressure.
Agile Supply Chain & 7–15 Day Dispatch
Strategic positioning near major eastern seaports (Lianyungang, Qingdao, Shanghai) enables continuous containerized dispatch within 7 to 15 business days. Direct factory sourcing removes intermediary margins and guarantees raw material traceability for international engineering procurement.

Integrated Formwork & Building Material Solutions
Tailored macro-solutions designed for construction conglomerates, commercial developers, and regional distributors.
High-Rise Monolithic Formwork Systems
For skyscraper cores, shear walls, and floor slabs, custom-cut PVC foam boards integrate seamlessly with aluminum frame climbing systems. Their consistent thickness tolerances ensure pristine concrete surface flatnesses meeting fair-faced architectural concrete (Exposed Concrete) standards.
Hydraulic & Marine Infrastructure Works
In bridge pier casting, drainage culverts, subway tunnels, and marine docks, traditional timber formwork quickly decays due to humidity and saltwater exposure. China PVC plastic shuttering panels offer complete corrosion resistance, acid-alkali immunity, and total waterproof performance.
Mixed-Container One-Stop Sourcing
Optimize container freight costs by bundling construction PP/PVC plastic formworks with internal floor finish products. As a multi-disciplinary manufacturer, Greenstar New Materials facilitates mixed loading of 18mm PP Hollow Formwork together with rigid SPC core flooring or LVT vinyl planks.
Localized Application Scenarios & Best Practice Guide
Operational instructions compiled by Greenstar field service engineers to ensure flawless execution on construction job sites worldwide.
Cutting & Sizing
Utilize carbide-tipped alloy saw blades (100–120 teeth) operating at high RPMs (above 3000 RPM). Ensure clean straight cuts without micro-burrs along panel edges.
Nail Spacing & Joist Layout
Space timber or steel purlins at 200mm–250mm intervals for 15mm/18mm floor slab panels, and 150mm–200mm for vertical shear wall shuttering to prevent deflection during pour.
Thermal Gap Reservation
Because synthetic polymers expand slightly in hot weather, leave a 1mm to 2mm expansion gap between adjacent board seams. Seal gaps with waterproof PVC tape or foam strips.
Stripping & Storage
Strip panels gently using wooden wedges rather than sharp iron crowbars. Stack stripped plastic boards horizontally on level pallets away from direct prolonged thermal distortion.

Frequently Asked Questions by Global Procurement Managers
In-depth technical answers curated by Greenstar’s engineering export department.
What is the fundamental engineering difference between PVC foam formwork and PP hollow formwork?
PP hollow formwork is extruded from polypropylene with an internal vertical rib lattice structure. It is significantly lighter (0.50–0.60 g/cm³), making it extremely easy for workers to handle manually on high-rise slab decks without cranes. It typically offers 30 to 60 reuses at a lower initial cost per sheet.
How do PVC and PP plastic formworks perform under extreme ambient temperatures?
Can PVC plastic formwork boards be nailed, sawed, and drilled using standard woodworking tools?
Why is no demolding oil or release agent required during concrete pouring?
What customization options are available for OEM / bulk export orders?
- Custom Dimensions: Standard sizes (1220x2440mm, 915x1830mm) plus custom lengths up to 6000mm.
- Thickness Options: 8mm, 10mm, 12mm, 14mm, 15mm, 18mm, and 20mm.
- Density Adjustment: Tailored core densities to balance board weight and flexural strength.
- Branding: Edge printing, backside laser engraving, and custom export pallet packaging.
What is Greenstar's typical delivery timeline and container loading capacity?
- 18mm PP Hollow Formwork: ~1,350 to 1,500 sheets (loose loaded / palletized).
- 18mm PVC Solid Formwork: ~600 to 700 sheets (due to weight limits).
Can we mix plastic formwork and indoor vinyl flooring (SPC/LVT) in the same shipping container?
