3M™ Dyneon™ PTFE Fine Powder TF 2021Z is recommended for the manufacture of unsintered thread sealing tapes, electrical tapes, joint sealings and tubings processed at lower to medium reduction ratios (RR).
Product grade with lower extrusion pressure than 3M™ Dyneon™ PTFE Fine Powder TF 2025Z. Therefore the applicable reduction ratio reaches a low to medium level (20 – 500:1). It can be highly stretched without breakage. 3M™ Dyneon™ PTFE Fine Powder TF 2021Z is the preferred grade for unsintered thread sealing tapes, electrical tapes for wrapped wire and cable insulations, expanded joint sealings and middle-sized tubings with relatively high green strength.
