About polymer examples
Where to Find Polymer Examples Suppliers?
Global supply of polymer examples is concentrated in China, with key manufacturing hubs in Zhejiang, Fujian, and Guangdong provinces. Yiwu and Ningbo in Zhejiang specialize in craft-grade polymer products such as modeling clays and decorative components, supported by dense networks of raw material suppliers and packaging providers. Xiamen in Fujian has emerged as a center for industrial thermoplastics, including POM, PP, and PPSU, leveraging regional expertise in plastic compounding and chemical processing.
These clusters enable integrated production cycles—from resin synthesis to finished goods—reducing lead times and logistics costs. Suppliers benefit from localized access to petrochemical feedstocks, pigment manufacturers, and extrusion equipment, allowing rapid prototyping and batch adjustments. Buyers can expect MOQs ranging from 1 kilogram for specialty chemicals to 25 kilograms for compounded plastics, with standard lead times of 7–15 days post-payment confirmation. The ecosystem supports both high-volume procurement and small-batch customization across diverse polymer types.
How to Choose Polymer Examples Suppliers?
Selecting reliable partners requires systematic evaluation across technical, operational, and transactional dimensions:
Material & Application Verification
Confirm the supplier’s core competencies align with your required polymer type—whether thermoplastic (e.g., PP, POM), thermoset (e.g., epoxy resins), or water-soluble polymers (e.g., polyacrylamide). Review product listings for consistency in specifications such as melt flow index, tensile strength, and thermal stability. For industrial applications, demand full datasheets and compatibility testing reports.
Production and Customization Capacity
Assess scalability through infrastructure indicators:
- Minimum monthly output capacity exceeding 10 metric tons for bulk orders
- In-house formulation capabilities for color, additive, or molecular weight modification
- Availability of free sampling (offered by 80% of verified suppliers) to validate material performance
Cross-reference customization claims with actual product variety—suppliers listing over 400 active SKUs typically have modular production systems suitable for OEM requests.
Quality Assurance and Compliance
Prioritize suppliers with documented quality management systems. While formal ISO 9001 certification is not universally listed, consistent on-time delivery rates above 90% and response times under 4 hours indicate operational discipline. For export-bound materials, verify compliance with REACH, RoHS, or FDA standards where applicable, particularly for food-safe or medical-grade polymers.
What Are the Best Polymer Examples Suppliers?
| Company Name | Main Products | Min. Order Quantity | Price Range (USD) | On-Time Delivery | Avg. Response | Reorder Rate | Online Revenue | Customization Options |
|---|---|---|---|---|---|---|---|---|
| Yiwu City Jintong Jewelry Factory | Clay Crafts (844), Resin Crafts (499) | 1–10 bags | $0.42–6.85 | 100% | ≤4h | <15% | US $2,000+ | Color, design, packaging |
| Ningbo Dongbo New Energy Co., Ltd. | Polyether, TPU, Polyester Polyol | 1,000 kg | $1.30–5.20 | 91% | ≤2h | 27% | US $340,000+ | Material blend, labeling, logo |
| Yiwu Liaoliao International Trade Co., Ltd. | Resin Crafts (1,127), Clay Crafts (194) | 1–3 bags | $1.44–11.55 | 88% | ≤24h | <15% | US $2,000+ | Size, color mix, shape |
| Realfine Chemical (wuxi) Co., Ltd. | Cationic Polyacrylamide, PDADMAC | 1 kg | $0.99–3.99 | 100% | ≤2h | <15% | US $360,000+ | Type, packaging, application tuning |
| Xiamen Keyuan Plastic Co., Ltd. | POM, PP, PC, ABS Raw Materials | 25–1,000 kg | $1.00–23.00 | 100% | ≤2h | 26% | US $130,000+ | Flame retardant, glass fiber, color |
Performance Analysis
Industrial-grade suppliers like Realfine Chemical and Xiamen Keyuan offer low MOQs (as little as 1 kg) and high responsiveness (≤2h), making them ideal for R&D and pilot production. Ningbo Dongbo and Xiamen Keyuan cater to large-scale manufacturing with bulk pricing and extensive material databases. Craft-focused suppliers such as Yiwu Jintong and Liaoliao provide ultra-low MOQs and design flexibility but serve niche markets with limited reorder frequency. Buyers seeking technical polymers should prioritize suppliers with documented material testing and formulation experience, while craft buyers benefit from visual product catalogs and sample availability.
FAQs
How to verify polymer supplier reliability?
Evaluate on-time delivery history (target ≥90%), response speed (≤24h preferred), and transaction volume. Request safety data sheets (SDS) and, where applicable, regulatory compliance documentation. Conduct video audits to confirm laboratory or production floor operations.
What is the typical sampling process for polymer materials?
Free samples are commonly offered for chemicals and raw plastics (up to 1 kg). Lead time for sample dispatch is typically 3–7 days. Buyers should cover shipping costs unless committing to a follow-up order. For custom formulations, expect a 7–10 day development period before sampling.
Can suppliers customize polymer properties?
Yes, many suppliers offer tailored solutions including color matching, UV resistance, flame retardancy, and viscosity adjustment. Realfine Chemical and Xiamen Keyuan explicitly list molecular-level modifications. Minimum order quantities for customized batches start at 500–1,000 kg depending on complexity.
What are standard payment and shipping terms?
Common payment methods include T/T and LC at sight. Shipping options vary: air freight for samples (3–7 days globally), sea freight for bulk orders (20–35 days). FOB terms are standard; CIF arrangements are available upon request. Ensure proper classification under HS codes 3901–3914 for customs clearance.
How to assess material quality before bulk ordering?
Always test samples for physical properties such as hardness, elongation at break, and thermal deformation temperature. For food-contact or eco-sensitive applications, require third-party lab reports verifying absence of phthalates, heavy metals, or non-biodegradable components.
