H Blowing Agent
The supplied H manual describes a blowing agent used principally in rubber, releasing gas on heating to form cells.

What this grade is designed to evaluate
The supplied H manual describes a blowing agent used principally in rubber, releasing gas on heating to form cells.
H and low-temperature H are separate records. The manual’s isolated plastic abbreviation “PVE” is unclear and has not been expanded into an application claim.
Application direction and selection conditions
H is described for natural and synthetic rubber. The manual also mentions PVC and selected plastics, requiring application-specific evaluation.
Provide the exact compound, cure system, actual material temperature, residence time and target cells. A material name alone is not sufficient to establish suitability. Finished-part performance must be verified on the customer’s formulation and equipment.
Values in the supplied model manual
Reference values below belong only to H. They are not a current batch certificate; methods, revision and acceptance limits need confirmation.
| Property | Manual reference | Status |
|---|---|---|
| Appearance | Pale yellow powder | Manual description |
| Decomposition temperature | ≥200 °C | Method/revision pending |
| Fineness | 6–10 μm | Size definition pending |
| Gas yield | 240 ± 10 ml/g | Test conditions pending |
| Packaging | 25 kg, lined carton or kraft bag | Confirm actual order |
Pending confirmation Current TDS/SDS/COA, test methods and batch acceptance criteria remain pending; do not transfer these values to another model.
Keep gas release aligned with the process
H and low-temperature H are separate records. The manual’s isolated plastic abbreviation “PVE” is unclear and has not been expanded into an application claim.
Record the formulation, cure/crosslinking system, dispersion, actual material temperature, pressure, residence time and cooling. No universal dose, reduction in odour, weight saving or mechanical-property guarantee is assigned to this grade.
Compare a baseline, a replacement and an optimised trial
- Current baseline: keep the existing compound, blowing agent, dosage and process; record the current result.
- Direct replacement: change only the candidate blowing agent to distinguish the grade effect.
- Optimised condition: review temperature, time, line speed, pressure or cooling within the customer’s permitted range.
- Alternative route: compare a second grade or a compound route where the evidence supports it.
Record density, cell distribution, shrinkage, colour, mechanical properties, odour and process stability. The customer’s finished-part specification determines acceptance.

- COA
- Results for the supplied batch, separate from general brochure values.
Pending confirmation Current model-specific TDS/SDS/COA and applicable original reports are not attached to this preview. No certificate or download button is fabricated.
Packaging, storage and handling
The supplied manual lists a 25 kg pack with an inner plastic liner, in a carton or kraft paper bag. Confirm the order’s pack format and destination requirements separately.
Its storage note calls for a cool, dry place away from sparks, fire and heat. Use the current grade-specific SDS for safety instructions, emergency measures and transport classification. The manual is not a replacement for that document.
Pending confirmation Shelf life, MOQ, dispatch time, pallet/loading plan and current transport classification require order-specific confirmation.
Questions for a model-specific trial
Can another grade use the same parameters?
No. Keep the model, manual, batch and test method together; run a controlled comparison for a replacement.
What should the trial compare?
Density, cells, surface, dimensions, mechanics, odour/chemical requirements and process stability against the current baseline.
