IMERYS is a major supplier of high quality mineral additives to the plastics and film industries throughout the world.
The Imerys product portfolio is unequalled in its breadth and encompasses a full range of products from highly functional surface-treated additives to economical extenders. Strong technical understanding of our products and their polymer-based applications complements the natural value of the minerals we supply.
In various applications, Imerys calcium carbonates and kaolins can reduce cycle time, improve processability, and improve mechanical and rheological properties. Our products are used in PVC, polyethylene, polypropylene and unsaturated polyesters. Some Imerys products are well suited as antiblock or in plastic for electrical insulation. Others aid pore formation for breathable film and opaque BOPP.
In the PVCu pipe and window profile industries coated calcium carbonates to enhance physical performance and maintain good colour and gloss.
For Thermosets we can supply a range of high whiteness materials where colour is critical and low cost materials where filling / bulking is needed.
Imerys mica products provide benefits to plastic composites, by increasing tensile and flexural strength, tensile modulus, and heat deflection temperature and greatly reducing warpage and shrinkage. Barrier properties also are greatly improved.
All of our products are supported by a high standard of technical service, product development and research from a team of highly experienced scientists and specialists in the application of calcium carbonates and kaolins in the plastic and film industries. Please refer to these sections for examples of innovative products.
