Fluoroelastomer Micropowder (FMP) is the product of the proprietary FRS process. It
differs greatly from the old fashioned "regrind" because it is chemically and
physically active, and participates in the polymer matrix.
The patented FRS process is a proprietary wet grinding process that ensures a uniform,
active particle.
Collection
FKM By-product (flash, scrap, sprues, runner system, and other fallout) is generated by
each heat of the molding process. Normally, the customer already has a system of
collecting this material, and transporting it to an area outside the molding area. In the
FRS process, this material must be collected, kept free of contamination, and subsequently
shipped to FRS for processing.
It is no more costly to collect this material for recycling than it is to collect it and
send it to the waste disposal area, but some employee training is needed to make sure the
material is properly identified, and is packaged so as to be preserved during shipping.
FRS will gladly help with the training process to ensure the preservation of the product
stream.
Inspection and Unloading
At the FRS site, the material is carefully inspected using a four-part identification
process, tested for material identification, and unloaded into the FRS manufacturing
process.
The inspection and unloading processes are part of FRS’ ISO9001:2000 certified
quality system. Records are retained on each shipment received, and corrective actions are
requested of each “supplier” in the event of a product quality issue.
Processing
The process is conducted at ambient temperature in a proprietary, highly controlled
manufacturing process that ensures product integrity.
Packaging and Inspection
Each lot of FRS-170 Fluoroelastomer Micropowder is packaged according to customer
specifications (the product is frequently pre-weighed to eliminate a step in the
customer’s process).
The material is thoroughly tested for identification, moisture level (less than 0.5%) and
particle size before shipping.
FRS has received ISO9001:2000 certification, and is committed to the continual improvement
of its quality system.
Fluoroelastomer Micropowder (FMP) is the output of the FRS Process. The highly controlled
FRS particles flow 100% through a 170-mesh screen, and contain active curative and polymer
crosslinking sites.
This particle morphology allows the material to form an intimate physical interaction with
the surrounding compound matrix, allowing use of up to 30 PHR of the FMP directly into the
original compound without significant deterioration of compound physical properties.
FMP is not the same as “regrind”, which is coarsely ground product from
old-fashioned processes.
