Calcium Sulfate Whiskers for Polymer and Rubber Trials
If you are evaluating calcium sulfate whiskers in rubber or polymers, confirm both the calcium-sulfate phase and the actual whisker form.
Relia's listed candidates need a grade-specific review of hydration, morphology and supplied condition.
- Identity
- CaSO4 form and hydration
- Shape
- Length, diameter and aspect ratio
- Result
- Dispersion and mechanical acceptance
From Your Requirement to a Defined Grade
Relia manufactures calcium sulfate materials in China through its own factories.
Our proposal should identify the actual calcium sulfate grade before discussing a whisker application. Give us the polymer or rubber system, processing conditions and required morphology. Phase and aspect-ratio evidence belong with the sample; a whisker-related title alone does not define either measurement.

The Whisker Identity
CSW-30H, CSW-30 and XM-CS300 are separate calcium-sulfate-whisker entries. Their titles and model codes help identify candidates, but they do not provide a complete length-to-diameter distribution or prove a reinforcing result. We connect phase, moisture condition and morphology to your intended compound before selecting a sample.

Whisker Grades with Separate Identities
| Review area | Listed data and acceptance basis | Use in your selection |
|---|---|---|
| CSW-30H · 6005 | The title uses an anhydrous designation and the entry lists more than 98% CaSO4. Confirm phase and moisture condition. | Connect the limit with storage, handling and your processing conditions. |
| CSW-30 · 5996 | A separate industrial whisker listing with more than 98% CaSO4. Do not infer identical morphology from similar assay. | Keep chemical identity, assay basis and the actual offered grade in the same specification. |
| XM-CS300 · 5972 | A rubber-focused anhydrous-designated entry. Request the actual length, diameter and surface information. | Use this item to define the candidate and the evidence needed for your application. |
| Compound evidence | Agree dispersion, processing and the mechanical or dimensional results needed for the intended polymer or rubber. | Use this item to define the candidate and the evidence needed for your application. |

Use these listed candidates to start a grade-specific discussion with us.
A Matrix-Specific Comparison
Compare the proposed whiskers in the actual compound, retaining the mixing and processing history. Review dispersion with the relevant mechanical and dimensional results. A high CaSO4 assay establishes a chemistry field; the whisker geometry and the compound trial establish whether the candidate fits your purpose.
Ordinary powder
Is not a whisker specification.
Photo appearance
Does not prove microscopic dimensions.
Universal claims
Need matrix-specific evidence.
Crystal Formation and Phase-Sensitive Finishing
Controlled crystallisation can produce elongated calcium sulfate particles, while phase, hydration and finishing conditions influence the resulting material. Later drying or processing can change the relevant state or shape. Use phase identification and morphology evidence for the proposed grade, then connect that evidence to the compound after its actual processing cycle.
Define the calcium sulfate
Phase and hydration state are part of the proposed material identity.
Form elongated crystals
Controlled crystallisation, including hydrothermal routes in published research, can produce whisker morphology.
Separate and finish
Finishing and handling must be considered with the phase, hydration and particle form being offered.
Check the processed material
Relate the supplied morphology to the compound after its actual preparation cycle.
- Phase
- Use evidence identifying the actual calcium-sulfate state.
- Morphology
- Retain length, diameter or aspect-ratio evidence appropriate to the grade.
- Use
- A whisker trial needs its own finished-compound acceptance rather than a generic powder equivalence.
Purchasing with a Defined Scope
Keep the accepted trial, filler sample and grade specification connected. We discuss repeat supply against the actual proposed material. Changes to phase, source or processing can then be reviewed on the same basis.
Continue Your Material Selection
If you need acicular wollastonite for a polymer composite, buy the particle shape as carefully as the chemistry.
If you make PP mouldings, a stiffer part is useful only if impact, shrinkage and warpage remain acceptable.
If you buy calcium carbonate for an industrial rubber compound, match the filler to the rubber, cure system and finished-part limits.
