Can we directly send all the unusable rubber to FKMR® for recycling?
Firstly, we will request the customer to provide 1 kg sample of scraps for testing. Our FKMR laboratory will assess whether it can be recycled. Once the evaluation is complete, we can proceed to the next step, which is the bulk recycling process.
Do we need to differentiate the rubber hardness for recycling?
Yes, only if the hardness is over 85 Shore-A, strict segregation is necessary in order to control the hardness of recycled materials effectively.
Do we need to separate the curing system into bisphenol and peroxide systems?
No, leave it all to FKMR Laboratory! The curing system of the recycled FKM would be bisphenol.
Do we need to differentiate colours?
Yes, Distinction is needed, with each batch primarily consisting of a single colour. Currently, black and brown are the primary colours.
Can rubber mixed with other rubbers, such as HNBR with EPDM, be recycled?
No, we only accept one type of rubber at a time without any mixture of other rubbers. If the initial assessment in the FKMR laboratory reveals any contamination with other rubbers, we won't be able to proceed with the next recycling steps.
How much quantity of the scrap do I need to convert it to recycled FKM?
Basically, our minimum recycling quantity is 1000 kg. We will recycle the entire amount in a 1:1 ratio, resulting in 1000 kg of recycled FKM.
What distinguishes FKMR's exclusive recycling technology from the traditional regrind method using FKM powder filler?
How does the FKMR® program recycle the fluoroelastomers? And how to recycle without regrinding?
FKMR® program uses it's latest technique to recycle fluoroelastomers, see the figure below for explanation.
