Linde Canada, an affiliate of Linde North America has signed a long-term supply contract with a leading producer of crumb rubber in the US and Canada – Liberty Tyre and Rubber.
Linde Canada has agreed to supply liquid nitrogen on a long term basis for the cryo-grinding process at Liberty’s Brenner, Ontario rubber plant. The announcement has further galvanised the long-term liquid nitrogen supply agreement with Linde in the US, who has purely extended the remit to incorporate the Brenner operation.
Gene Allen, Head of the North East U.S. market, commented, “We are very proud that Liberty Tyre has shown confidence in Linde as its liquid nitrogen supplier. This agreement continues to build on our long-term, successful partnership with the company.”
The Brenner facility is a recent acquisition for Liberty Tyre. Jeff Kendall, CEO of Liberty Tyre, said, “Liberty Tyre was very pleased when we could extend our successful relationship with Linde from the U.S. to our new acquisition across the border in Canada. We look forward to working with Linde and identifying new opportunities in the future.”
The production process for making crumb rubber involves reducing the size of the tyre shred or chip. This is where cryogenic grinding is used as through the immersion of liquid nitrogen (-196˚C) tyre chips maybe frozen to reduce their size. The cooled rubber is then ground in an impact-type reduction device.
