DISPERSED PIGMENTS DISPERSIONS FOR PTFE COLORING Dispersed pigments for coloring PTFE are created to add color to PTFE parts manufactured by the PTFE fine powder paste extrusion process. Extrusion of colored PTFE insulation is done by incorporation of dispersed pigments in these same lubricants. PTFE 2.

In this study, a variety of plastic substrates (30 unique polymer compounds), including poly(acrylonitrile-co-butadiene-co-styrene), poly(butylene terephthalate), poly(etherimide), various thermoplastic elastomers (TPEs), poly(carbonates), and poly(amides), were screened for susceptibility to microbial attack using American Society for Testing and Materials (ASTM) G21 (fungi susceptibility), Japanese Industrial Standard (JIS) Z2801, and modified ASTM E1428-15a (bacterial suscep- tibility) test standards. Without proper engineering controls, this would challenge the applicability for TPEs under normal thermal processing conditions for extrusion and molding. Control samples (top row) are shown for comparison to samples post-incubation and washing (bottom row) TABLE 1 Summary of ASTM G21 results for initial susceptibility screening of untreated resins/compounds Fungal growth Resin/compound 4 = Heavy growth (61%– 100% coverage, fail) TPE, 6 formulations 3 = Moderate growth (31%–60% coverage, fail) Poly(urethane), 2 formulations 2 = Light growth (11%– 30% coverage, fail) Nylon-6,10, PBT, poly(amide) elastomer, ABS, 3 formulations, reinforced Nylon, 2 formulations 1 = Trace growth (

Roy Plunkett accidentally created polytetrafluoroethylene (PTFE). Most fluoropolymers, other than PTFE and polyvinyl fluoride (PVF), can be melt processed using conventional thermoplastic extrusion or molding techniques. 1SPI, “History of Fluoropolymers” https://www.fluorotec.com/news/blog/the-history-of-ptfe/
