3M™ Dyneon™ TFM™ 1705

Modified non-free-flowing suspension PTFE of the 2nd generation for compression moulding applications like diaphragms, shaped parts and skived films.

Special Features Meets ASTM D4894 Type III, Grade 1 classification, Produced by suspension polymerisation, Improved particle coalescence, Dense polymer structure with reduced void content, Low permeability.

• PTFE moulding powder with very small particle size is preferred for moulded parts requiring very good mechanical and electrical properties, a denser polymer structure, improved gel stability and flex life characteristics.
• 3M™ Dyneon™ TFM™ Modified PTFE Powder TFM 1705 is a non-free-flowing compression moulding powder for applications like shaped parts, large walled cylinders or blocks with reduced elephant foot, skived films of > 20 μm, linings in the chemical processing industry (CPI) and especially valve and pump diaphragms with improved flex life.
• Substantially lower deformation under load ("cold flow")
• Very good electrical and mechanical properties
• Improved gel stability
• Increased modulus of elasticity
• Good weldability
• Improved flex life characteristics
• Excellent chemical inertness
• Low friction behaviour
• Good flame retardance
• Exceptional temperature resistance
