Application in papermaking, paint, rubber, pigment, etc.
Papermaking industryPyrophyllite in pulp can fill the interspace
between wood fibers, greatly increase paper density, improve paper
fastness, increase paper opacity, brightness and smoothness, reduce
moisture absorption and improve printing pigment absorbent.
Paint industryPyrophyllite powder is mainly used as mulch or filler
of paint and can provide paint with good suspension property,
durability and viscosity to avoid abrasion and falling off.
Rubber industryUsed as blending agent to smooth rubber surface,
improve abrasion resistance and strength. Fine pyrophyllite powder
is used as filler of rubber cable and loose powder to prevent
rubber products from cementation.
Application in coating
Since pyrophyllite has stable chemical properties and strong acid
resistance, the use of it in coating can offer a good suspension
property, durability, excellent luster and fastness. Compared with
other fillers, it can increase the unit coating area. It is widely
used, especially in new environmental protection coatings.
Application in pesticide manufacture
Pyrophyllite has low hardness, stable chemical properties, low
moisture, strong acid corrosion resistance and many other features.
So it is used as blending material of pesticide. Pyrophyllite
powder added in pesticide as poison carrier has poison and moisture
absorption function and is beneficial for long-term effective
maintenance. Besides, since the dosage is large (above 90%), it can
dilute the toxic concentration and reduce the harm to human body
The pyrophyllite powder we produce has high whiteness, uniform
granularity and stable quality. Our company is equipped with
advance production and detection facilities to ensure the reliable
Pyrophillite is a kind of hydrous aluminum silicate mineral, with melting point
of 1,700℃, white, platy radial aggregate. It is of gloss,
toughness, chemical stability, low thermal expansion, low thermal
conductivity, low electrical conductivity, high insulating ability,
high melting point and favorable corrosion resistance.
Pyrophillite Chemical Composition: Al2O3≥25~30%, SiO2≤55~70%, Fe2O3≤1.0%. Whiteness≥85%
I. Due to high melting point and low thermal expansion, Pyrophillite is used to reduce sintering temperature, decrease shrinkage and
cracking, resist thermal expansion or used as filler in ceramics
industry, such as ceramic tile, sanitary ware, dinnerware and
porcelain electrical supplies.
II. Due to high melting point, Pyrophillite is used in refractory materials, or used to add to glass fiber raw
material in the form of alumina and monox to promote flowing, or
used as filler in insulating firebrick, refractory material of
furnace and kiln, or mold wash.
III. Due to chemical stability, acid and alkali corrosion
resistance, high insulating quality, whiteness, absorbing property
and flowability, it is used as carrier or filler in insecticide,
specialized fertilizer, paint, rubber, paper making, dyestuff,
pharmacy, sugar processing, cosmetics and plastic products.
