| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Moisture Content | Karl Fischer Titration | Quantifies water by coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Total Exchange Capacity | Acid-Base Titration | Measures functional group density via complete ion exchange followed by back-titration of displaced H+ or OH-. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular scattering pattern of laser light passing through a dispersed resin sample. |
| Bulk Density | Weight-Volume Method | Calculates mass per unit volume of freely poured dry resin using standardized cylinder and weighing. |
| Porosity | Mercury Intrusion Porosimetry | Measures pore volume and size distribution by quantifying mercury intrusion under controlled pressure. |
| Mechanical Strength | Crush Strength Test | Evaluates resistance to physical degradation by measuring force required to crush individual beads under compression. |
| Residual Solvents | Gas Chromatography (GC) | Separates and quantifies volatile organic residues using capillary column and flame ionization detection. |
| Heavy Metals | ICP-OES | Simultaneously quantifies trace metal impurities (e.g., Pb, Cd, Hg) after acid digestion and plasma excitation. |
| pH of Aqueous Extract | Potentiometric Measurement | Determines acidity/basicity of water leachate from swollen resin using calibrated pH electrode. |
| Ash Content | Gravimetric Analysis | Measures inorganic residue mass after high-temperature combustion (550-600 C) and cooling in desiccator. |
| Functional Group Content | Elemental Analysis (CHNS/O) | Quantifies nitrogen or sulfur content to infer amine, carboxyl, or other functional group loading. |
| Crosslinking Degree | Swelling Ratio Measurement | Estimates divinylbenzene content indirectly by measuring equilibrium swelling volume in specified solvent. |

1. How do you ensure product quality consistency?
We rely on a mature China-based manufacturing system and implement strict batch control and quality inspection for every shipment. Our production process complies with ISO 9001 standards, and a COA is provided for each batch to ensure consistent and reliable quality.
2. Do you offer competitive pricing for bulk orders?
Yes, as a China-based manufacturer and bulk supplier, we provide tiered pricing based on order volume. We support FOB and CIF quotations, as well as L/C payment terms for large transactions to meet international trade requirements.
3. Can you support large-volume or long-term supply?
We have stable production capacity and a well-established supply chain, enabling continuous bulk supply. We support ton-level and container-level orders, as well as long-term cooperation projects.
4. What is your typical lead time?
For in-stock products, shipment can be arranged within 1–3 days. For bulk packaging or customized orders, lead time depends on the specific quantity and production schedule.
5. What documents do you provide?
We can provide complete documentation upon request, including COA, SDS, TDS, and other compliance certificates, meeting industrial procurement and export requirements.
6. Can you customize product specifications or packaging?
Yes, we support customization of parameters such as purity, impurities, residual solvents, and heavy metals. We also offer various bulk packaging options, including 25kg bags, drums, and IBC tanks, suitable for industrial applications and transportation.
7. What shipping options do you support?
We support both FCL (Full Container Load) and LCL (Less than Container Load) shipments, and can flexibly arrange logistics solutions based on order size to meet bulk chemical export needs.
8. Do you provide technical or application support?
Yes, we provide basic application guidance and technical support based on industry experience to help customers optimize product usage.
9. How do you handle compliance and export regulations?
We are familiar with international trade and export regulations, ensuring all products comply with relevant requirements. We also provide complete documentation to support smooth customs clearance and global delivery.
