ALTIFIL™ and ALTIPLUS™ products are versatile additives that can be used in manufacturing rubber products as a processing aid, functional filler, and dusting and mold release agent. The addition of a platy filler in rubber helps to reduce cost, lubricate molds, reduce the viscosity of the rubber compounds which helps in the processing of molded parts and tires, and prevents surfaces from adhering together during production. Several properties of pyrophyllite that affect the quality and smoothing of rubber are the platy structure, smoothness, greasiness and chemical inertness, which provides good permeability and weathering of the final product.

Applications include:


  • Hoses
  • Seals
  • Fire-resistant cables
  • Tires
  • Automotive parts
  • Industrial mechanical goods
  • Fire resistance and mechanical properties such as tear, and other mechanical rubber goods to improve processing


Pyrophyllite is a key component in commercial production of E-Glass fibers, which enables the elimination of sand in the batch and improves batch-to-melt conversion efficiency and lowers conversion energy.


Trinity offers a high brightness, high aspect ratio product that replaces talc as a reinforcing additive for strength.


Pyrophyllite’s presence in agriculture includes its use as an anti-caking agent and moisture barrier in feed pre-mixes, enhancing the flowability and effectiveness of agricultural products.


In ceramics, pyrophyllite is employed to manufacture high-temperature porcelain and whiteware, ensuring consistent and robust finished products in kiln firing processes.


Pyrophyllite’s versatility extends to the paint and coatings industry, where it acts as an extender and corrosion-resistant pigment, enhancing the performance of coatings and paints.
