PP / PA reinforcement grade
High-aspect-ratio wollastonite for PP and PA formulations. Specify retained morphology after extrusion, dispersion and the required balance of stiffness, impact and shrinkage.
PRODUCTS / APPLICATION-SPECIFIC WOLLASTONITE
A grade built around
your process.
Start with your application, then define the chemistry, particle distribution, morphology and treatment you need.
SIX GRADE SELECTION PROGRAMMES
Specify the application.
Then select the grade.
Choose a grade family and define the parameters that matter in your process. Particle distribution, morphology, chemistry and treatment are agreed for the selected material.
Low-iron, high-brightness coating grade
Define brightness, Fe₂O₃, full particle-size distribution and film appearance for your coating or binder system.
Low-oil-absorption industrial coating grade
Select against oil absorption, viscosity, dispersion and film-performance targets in the actual protective-coating formulation.
Acicular friction-material grade
Needle-shaped mineral for asbestos-free formulation programmes, with source-specific impurity evidence and friction-system qualification.
Fast-firing ceramic grade
Match chemistry, iron content and sizing to trials targeting a shorter cycle or lower firing temperature, while retaining fired-body quality.
Surface-modified grade
Specify silane or titanate treatment, resin compatibility and moisture limits. Confirm treatment chemistry and dispersion in the intended compound.
Grade-family names describe the intended application and selection targets. Exact values, treatment chemistry and acceptance limits are confirmed in the grade specification. BD200 is one documented reference example ↗
A CLOSER LOOK AT THE MATERIAL
From mineral source
to your selected grade.
Explore the raw mineral in these supplied photographs. The powder grade is selected separately to meet your application and processing requirements.
Natural surface detail
A closer view of the mineral before it is processed to the selected powder specification.
Raw material, in perspective
The measuring tape shows the scale of the photographed pieces; finished-powder sizing is defined in the grade specification.
Photographs illustrate material appearance. Grade-specific brightness, purity, particle size and aspect ratio are confirmed through the agreed specification and test reports.
BUILT AROUND YOUR PROCESS
Designed around
higher-value applications.
We supply application-specific materials for higher-value ceramic, composite, polymer and coating products. The starting point is your required performance, translated into a clear mineral specification.
CERAMIC BODIES · SANITARYWARE
Chemistry that works
with your firing process.
Discuss a wollastonite specification for your ceramic formulation, including chemistry, iron content and particle size. Confirm performance through trials using your own firing cycle.
