Reprolon Texas Purchasing & Grading Criteria for PTFE Scrap
Grade 1 Scrap
Grade 1 Scrap includes clean items fabricated from virgin granular PTFE molding powders, unmodified by pigments or fillers. Typical examples are: cores; cracked billets and preforms; rod, tube, and sheet ends; chucking stub; out-of-tolerance and obsolete parts; heavy tape punchings and trimmings; and exceptionally clean machine turnings uncontaminated by oil.
Grade 2 Scrap
Grade 2 Scrap includes items similar to Grade 1 Scrap; however, the products may be fabricated from partially or totally reprocessed PTFE, with some easily removable contamination allowable.
Grade 3 Scrap
Grade 3 Scrap includes etched, degraded virgin, or reprocessed PTFE. Items with deeply embedded contaminants such as rusty valve seats and gaskets, wire and cable jackets, oil contaminated machine turnings and the like.
Unusable Scrap
Unusable Scrap is extremely difficult to remove excessive amounts of oil and contaminants from some machine turnings and other types of scrap. Proper care of these contaminated products should be exercised during their collection and storage. Any overly contaminated scrap, particularly oily pieces, will greatly reduce its value and may downgrade the entire container as unusable. Freight charges on unusable scrap will be deducted from the value of the usable scrap.
