What is the difference between LVT and SPC flooring?

LVT (luxury vinyl tile) uses flexible PVC layers and is usually glue-down or click installed, offering a softer, quieter feel. SPC (stone plastic composite) has a rigid core made of limestone powder and PVC, which gives higher dimensional stability, full waterproof performance and a floating click-lock installation over most existing hard floors.

Do you provide samples before a bulk order?

Yes. Samples are available so buyers can check color, surface texture, thickness and click profile before confirming a bulk order. Contact our sales team with your target specification and destination.

What is your typical delivery time?

With eight production lines located near major ports, standard orders are typically dispatched within 7 to 15 days after order confirmation. Exact lead time depends on specification, customization and order volume.

How can I check the quality of PP hollow plastic formwork?

Compare panel weight per sheet for the same thickness, inspect surface flatness and rib structure, and ask for performance under heat and cold. Low-grade panels tend to warp or show wave-like deformation in summer and crack in winter. Our blog explains simple on-site tests.

Can you produce custom designs and private-label packaging?

Because we integrate product development, design and production, we can discuss custom decors, colors, thickness, sizes and packaging according to your market and order quantity.

Direct Factory Export Lines — Waterproof SPC Flooring, Luxury Vinyl Tiles (LVT), & High-Density PP Formwork Panels

1. Executive Analysis: China's Role in Global Waterproof SPC Flooring Manufacturing

As global building architecture accelerates toward high-durability, eco-friendly, and moisture-resistant surface solutions, Stone Plastic Composite (SPC) flooring has emerged as the definitive benchmark for modern commercial and residential interior spaces. Originating as an evolutionary breakthrough over traditional Luxury Vinyl Tiles (LVT) and laminate floorings, SPC combines natural limestone powder (Calcium Carbonate, CaCO3) with polyvinyl chloride (PVC) stabilizers under high-temperature extrusion parameters. The resulting rigid core matrix exhibits zero swelling, absolute dimensional stability, and complete immunity to water immersion.

Greenstar New Materials Shuyang Co., Ltd. stands at the forefront of this industrial transformation. Located in Suqian City, Jiangsu Province—one of China’s premier advanced materials manufacturing hubs—our enterprise operates a 3,000㎡ dedicated R&D testing core, 8 automated high-capacity extrusion and lamination lines, and integrated global supply chain logistics. With over 15 years of continuous engineering research, Greenstar has formulated over 100 chemical balance iterations to optimize flexural modulus, drop-impact toughness, and flame retardancy across global climate zones.

Key Engineering Fact (Information Gain): Unlike standard LVT flooring which relies on plasticized flexible PVC layers susceptible to thermal expansion and telegraphing, SPC rigid core features a dense crystalline structure (Density ≥ 2.0 g/cm³). This allows for floating click-lock installation directly over minor subfloor imperfections without telegraphic telegraphing or glue degradation.

2. Macro Industry Trends: The Shift Toward Waterproof Rigid Core Flooring

The global flooring industry is undergoing a structural realignment driven by strict environmental regulations, labor shortages, and evolving end-user expectations. Key macro market drivers include:

Rapid DIY Click Adoption

Rising installation labor costs in North America and Western Europe have driven demand toward floating click-lock systems (Unilin, Valinge 2G/5G). SPC flooring requires no adhesives, dramatically reducing labor time and site downtime.

Extreme Climate Resilience

Global climatic fluctuations require materials capable of withstanding extreme humidity and temperature deltas (-10°C to +60°C) without shrinking, cupping, or buckling—a key weakness of traditional wood laminates.

Zero-VOC & Phthalate-Free Standards

International environmental certifications (FloorScore, GREENGUARD Gold, REACH compliance) now dictate purchasing parameters. Premium Chinese exporters utilize 100% virgin PVC resins and non-heavy metal Ca-Zn heat stabilizers.

3. Technical Anatomy & Procurement Specifications Matrix

When specifying SPC flooring for large-scale enterprise contracts, commercial procurement managers must evaluate layer-by-layer technical parameters rather than superficial decorative optics alone.

Anatomical Layer	Material Composition	Standard Specification	Engineering Functionality
1. UV Surface Coating	Double Polyurethane + Ceramic Bead Additives	5 - 12 µm thickness	Prevents UV fading, provides stain/chemical resistance, and enhances micro-scratch defense.
2. Wear Layer	Transparent Rigid PVC Sheeting	0.3mm (12mil) to 0.7mm (28mil)	Determines Taber abrasion resistance (Group T rating); critical for commercial foot traffic.
3. High-Definition Decor Film	Rotogravure Printed PVC Film	3D High-Definition Wood/Marble Grain	Delivers hyper-realistic aesthetic textures matching natural timber, marble, or terrazzo.
4. Rigid SPC Core	Limestone (CaCO3) + Virgin PVC + Ca-Zn Stabilizer	4.0mm - 7.0mm (Density ≥ 2.0g/cm³)	Provides total waterproofing, structural rigidity, fire resistance (Class Bfl-s1), and click strength.
5. Acoustic Underlayment	Cross-Linked IXPE Foam / High-Density EVA	1.0mm - 2.0mm attached backing	Dampens impact sound transmission (Delta Lw 18-21dB) and enhances underfoot ergonomics.

4. Technological Roadmap & Thermal Stability Engineering

The most prevalent failure mode in inferior SPC products is post-installation warping, edge cupping, or lock-profile disengagement caused by unreleased internal stress during extrusion. Greenstar mitigates these risks through a triple-stage thermal annealing process:

STAGE 01

High-Precision Extrusion

Raw materials are blended at 180°C–210°C in twin-screw extruders. Automatic thickness gauges continuously scan across the web to maintain strict tolerance control within ±0.05mm.

STAGE 02

In-Line Thermal Stress Release

Immediately post-extrusion, SPC cores pass through a 40-meter tempering bath and thermal relaxation tunnel, removing residual molecular tension accumulated during roller calendering.

STAGE 03

Automated Click Profiling

Utilizing Homag and CUT-ALL high-speed diamond profiling machinery, click edges (Unilin/Valinge) are milled to exact geometric profiles, guaranteeing joint locking strength above >2.5 kN/m.

5. Integrated Commercial Solutions: Flooring & Construction Materials Synergy

Modern construction developers and wholesale importers frequently manage dual procurement workflows—interior decorative surfacing alongside structural formwork systems. Greenstar addresses this enterprise friction point by integrating manufacture of both Waterproof SPC/LVT Vinyl Flooring and Reusable PP Hollow Plastic Concrete Formwork Panels within unified export operations.

7. Comprehensive Enterprise FAQ & Technical Insights

In-depth responses to technical, procurement, and structural questions raised by international buyers.

What fundamental structural characteristics distinguish SPC flooring from conventional LVT?

LVT (Luxury Vinyl Tile) relies on multiple flexible PVC sheets laminated together, yielding a softer underfoot feel but requiring a perfectly flat subfloor and glue-down or light click installation. In contrast, SPC (Stone Plastic Composite) features a rigid solid core comprised of roughly 65% natural limestone powder (CaCO3) and 25% PVC resin. This dense structural core gives SPC superior impact resistance, complete 100% waterproof integrity, high tensile lock strength, and immunity to telegraphing over imperfect subfloors.

How does Greenstar guarantee dimensional stability under extreme ambient temperatures?

Dimensional stability is achieved by managing internal stress during extrusion and maintaining a calibrated CaCO3-to-PVC ratio. Greenstar subjects extruded SPC sheets to a continuous 40-meter thermal tempering bath followed by 24-hour controlled climate resting prior to click profiling. This guarantees linear expansion coefficients under ≤0.15% across operating temperatures from -10°C to +60°C (tested according to EN 434 / ISO 23999).

What sample evaluation support and custom OEM services are provided for distributors?

We provide express sample boxes containing customized plank thickness options (4.0mm, 5.0mm, 6.0mm), wear layer variants (0.3mm to 0.7mm), IXPE acoustic underlayment backings, and wood/marble film swatches. For volume distributors, we offer complete private-label OEM box printing, customized logo stamping, custom master carton design, and exclusive regional decor protection agreements.

How does PP Hollow Plastic Formwork performance compare to traditional Plywood formwork?

PP (Polypropylene) Hollow Plastic Formwork panels do not absorb water, eliminating swelling, warping, and delamination common in film-faced plywood. Greenstar PP formwork panels can be reused over 60 to 100 cycles depending on job site handling, dramatically reducing per-use concrete casting costs. Furthermore, smooth surface release eliminates the need for chemical release agents, yielding mirror-finish concrete surfaces ready for direct painting or plastering.

What is the standard order lead time and factory delivery workflow?

Standard 20ft/40ft full container load (FCL) orders are typically produced and dispatched within 7 to 15 days following deposit confirmation. Our dedicated export documentation team handles container loading inspection, customs declaration, Certificate of Origin generation, and bill of lading issuance to ensure seamless customs clearance at destination ports worldwide.
