FAQs

How much micronized rubber powder can I put in my formulation?
It depends on the application. Some applications can effectively use as little 5% in their formulations or up to 40% or more. Led by a team of experienced industry professionals and scientists, our Application & Development Center can help you determine the optimal amount to use in your formulation.
Where do you get your tires?
Our tires are collected, shredded, and then sent to us by one of the largest tire recyclers in the country.
What types of tires do you use?
Our core product line is derived from post consumer, end-of-life truck tires. Using this type of tire as feedstock offers us the ability to maintain consistency of the general composition of our rubber powders. We also use post-industrial rubber, such as pin vents and other tire-derived material.
What is the content of your product? Do you add anything to your rubber powders?
We add a minor amount of environmentally-friendly and safe processing aid, but that is it. Our product is mechanically processed meaning no other major chemicals added. Therefore, our customers receive a clean, metal and fiber free micronized rubber powder derived from the rubber material that they specify, giving them the inherit benefits of rubber for their end products. 
What types of rubber does your powder work with?
Currently, we work with whole tire rubber, tire tread buffings, and natural, nitrile, and butyl rubbers – and we are always open to looking at other types of rubber material.
How is your product similar/different to reclaim?
The difference between Lehigh’s micronized rubber powder and reclaim has to do mostly with the way it is treated during the manufacturing process. Reclaim rubber is, generally, chemically treated causing the properties of the base compound to degrade. Lehigh's rubber is mechanically treated, not chemically treated.
How do I formulate with micronized rubber powders?
Our micronized rubber powders are formulated into multiple applications, ranging from rubber compounds for a plethora of rubber goods to elastomeric and asphaltic coatings, olefin plastics, etc. Chemists and formulators in our Applications and Development Center are experienced in incorporation and formulation techniques for our rubber powders and are happy to assist you with any questions you may have. Go to the Contact Us section to get in touch with us.
Will using Lehigh’s Micronized Rubber Powders save me money?
Utilizing our rubber powders may indeed offer cost savings as it replaces other raw materials in your formulation. They also could provide your product with property enhancements and the ability to create a product that can be marketed as an environmentally-friendly alternative vs. your competition.
Is your product REACH compliant?
Our PolyDyne™ and MicroDyne™ products from whole tire rubber and buffing/peelings have been tested by two third party testing laboratories, TÜV SÜD and Akron Rubber Development Laboratory (ARDL), and are REACH compliant. 
Is your product safe?
Ground tire rubber has gone through extensive testing in the US and Europe by independent laboratories and government agencies regarding its health and safety. Ground tire rubber has been found to be safe in these specific application tests. A list of these tests and conclusions, including Lehigh Technologies’ third-party REACH/SVHC report, can be obtained by contacting your appropriate representative. 
How does using Lehigh’s Micronized Rubber Powders (MRPs) help protect the environment?
By incorporating MRPs into products, companies prevent waste from ending up in landfills, help preserve natural resources like oil (oil is used to make the products we replace), lower the amount of energy required to make the product, and lower greenhouse gases.
