Document-Based Approval
Technical documents matter before material approval, not after problems appear
In Hollow Glass Microspheres sourcing, TDS, COA and MSDS should not be treated as separate paperwork. Together, they help confirm whether a grade can meet technical requirements, whether the delivered batch is consistent, and whether the material can be safely imported, stored, transported and used.
For the updated grade system, TDS files are available for HGM15, HGM20, HGM22HS, HGM25, HGM50, HGM60 and HGM60HS. MSDS files are currently provided for HGM15, HGM22HS, HGM25, HGM60HS and HGM60. COA should be requested by batch number when shipment or incoming inspection is required.
- TDS helps judge technical suitability before sample testing.
- COA verifies whether the delivered batch matches the required quality window.
- MSDS supports safety, handling, import, storage and compliance review.
- For document-specific reading, continue with the TDS Guide, COA Guide and MSDS Guide.
Document Roles
Three documents answer three different engineering questions
TDS, COA and MSDS are often requested together, but they do not solve the same problem. TDS supports grade screening, COA supports batch verification, and MSDS supports safety and compliance review.
TDS
Can this material meet my technical requirements?
TDS helps engineers evaluate whether true density, compressive strength, D50 particle size, thermal conductivity and process behavior can match the target application.
- HGM15 to HGM60HS grade comparison
- Sample testing preparation
- Density and strength screening
- Application recommendation review
COA
Can the supplier consistently deliver the same quality?
COA verifies the actual delivered batch. It should be requested by product grade and batch number before shipment approval, incoming inspection or repeated purchasing.
- Batch traceability
- True density confirmation
- Particle size verification
- Moisture and floating rate review
MSDS
Can the material be safely imported, stored and used?
MSDS supports safety, handling, PPE, storage, transportation and regulatory review. It reduces uncertainty before the material enters the supply chain.
- Hazard classification
- Handling and storage
- Transportation review
- Workplace safety support
Understanding TDS before sample testing
A Technical Data Sheet is not just a product introduction page. For Hollow Glass Microspheres, it is the first document engineers use to judge whether a grade is technically suitable before trial formulation, process testing or internal approval.
The updated TDS center now covers HGM15, HGM20, HGM22HS, HGM25, HGM50, HGM60 and HGM60HS. Read density, D50, compressive strength and application recommendations together instead of comparing one number alone.
| Parameter | Why Engineers Check It |
|---|---|
| True Density | Determines lightweighting efficiency and final system density reduction. Current available TDS grades range from 0.15 g/cm³ to 0.60 g/cm³. |
| Compressive Strength | Indicates whether microspheres can survive pumping, mixing, molding, extrusion or high-shear processing. Current available values range from 500 psi to 18000 psi. |
| Median Particle Size D50 | Affects surface finish, dispersion stability, viscosity behavior and processing compatibility. |
| Thermal Conductivity | Supports insulation, thermal barrier and heat-management design. The current TDS documents list 0.04–0.1 W/(m·k). |
| pH Value | Helps review compatibility with resin, coating, adhesive, slurry or elastomer systems. |
| Floating Rate | Reflects hollow sphere integrity and usable material quality. The current TDS documents list a floating rate above 99%. |
| Application Recommendations | Helps connect grade properties with coatings, adhesives, oil extraction, plastics, electronics, rubber, transportation and building materials. |

| HGM60HS | 0.60 g/cm³ | 23 μm | 18000 psi | Plastics, electronics, transportation and high-shear processing environments. | Download |
Note: TDS values are used for preliminary technical comparison. They should not replace incoming batch inspection, COA verification or application testing.
COA Verification
COA should be requested by grade, batch number and shipment lot
TDS shows the typical technical direction of a grade. COA shows the actual tested results of a specific production batch. For long-term purchasing, this distinction is critical.
The current Material System page focuses on the updated TDS and MSDS document package. If a project requires incoming inspection, shipment approval or supplier qualification, the corresponding COA should be requested according to the actual grade and batch number.
This avoids mixing old sample COA data with new shipment documents and keeps the document system cleaner for HGM15, HGM20, HGM22HS, HGM25, HGM50, HGM60 and HGM60HS.
What a batch COA should confirm
Use this checklist for shipment approval, supplier qualification and incoming inspection.
| COA Item | What It Confirms | Why It Matters |
|---|---|---|
| Product Grade | HGM15 / HGM20 / HGM22HS / HGM25 / HGM50 / HGM60 / HGM60HS | Confirms the delivered grade matches the approved material. |
| Batch Number | Actual production or shipment lot | Connects the material to production, inspection and delivery records. |
| True Density | Measured density of the batch | Affects lightweighting efficiency and final formulation density. |
| D50 Particle Size | Measured median particle size | Affects dispersion, surface quality and viscosity behavior. |
| Compressive Strength | Batch pressure resistance result | Supports process survival and high-shear application review. |
| Moisture Content | Batch moisture level | Helps prevent caking, bubbling, poor dispersion and storage risk. |
| Floating Rate | Hollow sphere integrity indicator | Supports lightweighting consistency and usable material quality. |
| Quality Approval | Inspection conclusion and approval | Supports delivery acceptance and supplier document control. |
MSDS Compliance
MSDS reduces safety, logistics and compliance uncertainty before shipment
For international buyers, MSDS is more than a safety attachment. It supports customs review, warehouse acceptance, transportation classification, workplace protection and supplier approval. The current MSDS download group includes HGM15, HGM22HS, HGM25, HGM60HS and HGM60.
What MSDS helps you review
- Product Identification Product name, recommended use as lightweight filler, supplier information and grade reference.
- Hazard Classification The current MSDS files state that the material is not classified as hazardous under GB3000-2013 and OSHA HCS.
- Composition Typical composition includes soda lime borosilicate glass and synthetic amorphous crystalline-free silica.
- First Aid Measures Guidance for inhalation, skin contact, eye contact and accidental ingestion.
- Handling & Storage Dust control, ventilation, sealed storage and moisture prevention.
- PPE Review Safety glasses, respiratory protection assessment and exposure control.
- Transport Information The current MSDS files support logistics review and state transport is not regulated per U.S. DOT, IATA or IMO.
- NFPA / HMIS Rating Helps workplace teams understand health, flammability and physical hazard levels.
How engineers use TDS, COA and MSDS together
A complete material approval process does not stop at downloading one file. TDS, COA and MSDS should be reviewed in sequence, then verified through laboratory evaluation, pilot production and commercial approval.
This workflow helps reduce wrong-grade selection, failed sample testing, delayed customs clearance and repeated supplier approval work.
Review TDS
Determine whether the material is theoretically suitable for density, strength, particle size and application requirements.
Request COA
Verify whether the supplied batch quality matches specification and previous approval records.
Review MSDS
Confirm safety, transportation, storage and regulatory compliance before import or warehouse acceptance.
Laboratory Evaluation
Test real material performance under resin, coating, slurry, plastic, elastomer or lightweight composite conditions.
Pilot Production
Verify manufacturing compatibility, dispersion behavior, breakage rate and batch stability.
Commercial Approval
Approve the material for long-term purchasing, quality control and supply chain documentation.

If you are reviewing HGM documents, start from the right logic
Different project stages need different documents first. The right sequence helps prevent repeated communication, wrong-grade sampling, delayed approval and document gaps before shipment. For the updated grade system, TDS supports grade comparison, COA should follow the actual batch, and MSDS supports safety and compliance review.
Common documentation mistakes
- Using old HGM18, HGM38 or HGM46HS document links when the current page should follow the updated grade system.
- Only checking true density on TDS and ignoring D50, compressive strength and processing survival.
- Using a fixed public COA as if it represents every future shipment batch.
- Requesting MSDS only after shipment or warehouse approval has already started.
- Comparing suppliers by TDS values only without reviewing batch COA records.
- Ignoring packaging, moisture prevention and handling conditions before trial production.
What these mistakes may cause
- Wrong grade selection and failed sample testing.
- Outdated document links on the Material System page.
- Batch mismatch during incoming inspection or shipment approval.
- Customs, logistics or warehouse acceptance delays.
- Repeated formulation adjustment and higher testing cost.
- Quality disputes caused by missing or mismatched batch evidence.
Packaging & Handling
Packaging, storage and handling should be reviewed before trial production
Packaging and handling information is part of document review because moisture, contamination, mechanical impact and excessive shear may affect the final performance of Hollow Glass Microspheres. The updated grade system uses different carton and bulk bag weights, so packaging should be checked together with TDS and shipment planning.
| Grade | Carton | Bulk Bag | Shelf Life |
|---|---|---|---|
| HGM15 | 22 lb / 10 kg | 176 lb / 80 kg | 24 months |
| HGM20 | 30.8 lb / 14 kg | 242 lb / 110 kg | 24 months |
| HGM22HS | 30.8 lb / 14 kg | 264 lb / 120 kg | 24 months |
| HGM25 | 39.6 lb / 18 kg | 308 lb / 140 kg | 24 months |
| HGM50 | 66 lb / 30 kg | 462 lb / 210 kg | 24 months |
| HGM60 | 79.2 lb / 36 kg | 660 lb / 300 kg | 24 months |
| HGM60HS | 79.2 lb / 36 kg | 660 lb / 300 kg | 24 months |
Storage & Handling Guidelines
