Explore our primary range of specialized PVC roll materials, medical-grade components, and thermoplastic compounds engineered for international distribution.
Founded in 1996, Jiangsu Dahai Plastics Co., Ltd. has established itself as an elite, high-technology private enterprise specializing in the R&D, processing, and high-frequency calendering of custom PVC films, printing sheets, and advanced copolymer materials. Our industrial compound covers more than 120,000 square meters and generates an annual output surpassing 100,000 tons, driving domestic and export sales values over 1 billion RMB (approx. $180 Million USD).
Equipped with 20+ specialized, environment-aligned calender production lines and high-performance polymer extrusion machinery, we serve a global customer footprint across North America, South America, Europe, Southeast Asia, and Africa. By combining material chemistry innovation with stringent structural standards, we provide raw components that define reliability in heavy-duty commercial industries.
Inflatable structures operate under sustained internal pressure and dynamic external stresses. To guarantee structural longevity, our PVC formulations leverage advanced calender processing, precise plasticizer ratios, and optimized thermal bonding properties.
We combine high-K-value PVC resin (K-65 to K-70) with safety-certified plasticizers (DINP, DOTP, or bio-based plasticizers) to minimize volatile emission. This results in soft, high-flexibility film that retains elastomeric recall without chalking or micro-cracking over multi-year deployments.
The molecular design of our PVC inflatable sheet ensures an optimal dielectric dissipation factor. This allows rapid, clean high-frequency (HF) and hot-air welding, forming unified, leak-proof seams that withstand high air pressure and sheer stress thresholds.
Every roll integrates UV-absorbers, anti-oxidants, and optional anti-microbial additives. This protects the core polymer matrix against photo-degradation, biological decomposition in damp marine environments, and premature embrittlement from heat exposure.
The table below highlights the key physical metrics validated by our CNAS-accredited testing laboratories, demonstrating our compliance with global safety expectations:
| Property Parameter | Standard Reference Value | Testing Methodology | Industrial Relevance |
|---|---|---|---|
| Thickness Range | 0.08 mm to 2.50 mm (Customizable) | ISO 4593 / ASTM D374 | Enables applications from thin medical bags to heavy structural tarps. |
| Tensile Strength (Warp/Weft) | ≥ 18 MPa / ≥ 16 MPa (Film only) | ASTM D882 / ISO 527-3 | Ensures high resistance to bursts and tearing under rapid air inflation. |
| Cold-Crack Temperature | -25°C to -50°C (Arctic Grade) | ASTM D1790 | Allows outdoor deployment in severe winter climates without structural cracking. |
| UV Resistance | 1000+ Hours (Blue Wool Scale 7-8) | ISO 4892-2 Xenon Arc | Prevents discoloration and polymer cross-linking decay under solar radiation. |
| Flame Retardancy | B1 / NFPA 701 / California Title 19 | EN 13501-1 / ASTM E84 | Required for commercial event structures, bounce houses, and indoor inflatables. |
Our specialized PVC materials are modified to meet target specifications across distinct commercial, industrial, and clinical verticals.
PVC inflatable materials are not one-size-fits-all products; they must adapt dynamically to localized climates, regulations, and mechanical demands:
In regions such as the Middle East and Northern Australia, solar radiation speeds up photo-oxidation. We formulate these products with synergistic HALS (Hindered Amine Light Stabilizers) to prevent color fade, cross-linking, and micro-fissure leaking.
For applications like outdoor storage domes or inflatable emergency shelters in Northern Europe or Canada, standard PVC becomes brittle. Our arctic-grade formulations stay flexible at temperatures down to -50°C by utilizing low-temperature plasticizers.
In offshore structures, oil booms, and inflatable tenders, marine salinity and microbes cause bio-fouling and chemical stress. Our formulations integrate anti-microbial biocide agents that prevent fungal growth and protect the polymer seal integrity.
The global polymer industry is evolving toward sustainability and high-performance hybrid composites. Jiangsu Dahai Plastics Co., Ltd. is leading this shift with key developmental priorities:
As a leading Chinese manufacturer, Jiangsu Dahai Plastics Co., Ltd. offers significant production advantages, including raw material integration, stable pricing, and quick turnaround times:
Located in the heart of Jiangsu's petrochemical industrial zone, we maintain deep, stable contracts for raw PVC resins and plasticizer supplies. This protects our clients from market price swings and guarantees consistent material quality.
With 20+ automated production lines producing over 100,000 tons annually, we handle large volume orders with ease. Our standard lead times are 30-40% faster than smaller regional operations.
We are investing $140 million USD to build modern smart manufacturing lines for medical-grade materials. This project integrates automatic dosing, thickness monitoring, and real-time defect scanning to ensure highly consistent production runs.
Inflatable structures have transitioned from simple toys to crucial industrial systems. Modern applications include high-pressure pneumatic halls, environmental biogas containment domes, and emergency medical shelters. These heavy-duty applications demand materials that remain stable under pressure. Dahai Plastics works with engineering firms worldwide, supplying base PVC membranes that meet strict structural standards and remain gas-tight over long-term use.
Entering international markets requires strict compliance with chemical safety rules. Our in-house testing labs work closely with third-party verification agencies to ensure all products meet global chemical and environmental standards:
Our materials undergo testing to ensure they are free of restricted heavy metals and Substances of Very High Concern (SVHC), complying with European chemicals regulations.
For toy and recreational applications, our formulations are certified free of phthalate plasticizers and heavy metal residues, ensuring safe contact use.
Our medical films are produced under clean conditions to ensure chemical stability, biological safety, and strength, ideal for urine bags and enteral feeding pouches.
We believe that precise testing is key to ensuring consistent quality. Our testing laboratory is accredited by the China National Commission for Conformity Assessment (CNAS) and is equipped with advanced analytical instruments, including universal tensile testers, Agilent gas chromatography analyzers, electronic gloss meters, and environmental cold-tolerance chambers.
This allow us to verify the chemical makeup, mechanical strength, and environmental stability of our materials. Our technical teams also collaborate with leading universities to continuously research new formulas and improve the tear resistance and UV stability of our PVC products.
Our PVC film and raw materials are exported to over 10 countries and trusted by leading manufacturers worldwide.
Find answers to common questions about material selection, customization, and chemical compliance.
PVC (Polyvinyl Chloride) is preferred for inflatables because of its excellent compatibility with high-frequency welding, high tensile strength, chemical stability, and cost-effectiveness. When compounded with suitable plasticizers and stabilizers, it creates air-tight, durable structures that resist tears and environmental weathering.
We formulate our materials to meet specific safety standards like EN-71, ASTM F963, and RoHS. By using safe plasticizers like DINP, DOTP, or bio-based additives in our dedicated production lines, we ensure our toy and medical films are safe for sensitive applications.
Our standard MOQ for custom calendered PVC film runs is typically 2 to 3 tons per specification, depending on the requested thickness and color. For standard stock items, we can accommodate smaller trial orders. Please contact our sales department for details.
Standard PVC becomes brittle in very cold temperatures because of its glass transition characteristics. By adding specialized low-temperature plasticizers, we can adjust the material's properties so the film remains flexible and crack-resistant at temperatures down to -50°C.
Every production batch is tested in our CNAS-accredited laboratory. Standard checks include thickness verification, tensile strength, elongation limits, heat shrink rates, and color matching. We can also provide official analysis certificates (COA) for each shipment.
Standard manufacturing times are 15 to 21 days from order confirmation and deposit receipt. Shipping times vary by destination, ranging from 10-15 days for Southeast Asia to 30-40 days for Europe and North American ports. We handle all export packaging and customs documentation.
