What are the difference between PTFE and TFM 1600?
PTFE is also referred to as DuPont’s Teflon®, PTFE is a kindof thermoplastic fluoropolymer that consists of Carbon and Fluorine. This structure allows PTFE to be non-reactive to almost all chemicals and applied to severe chemical environments. PTFE is ideal for low cycle life applications.
3M™ Dyneon™ PTFE TFM1600 - TFM1600 is a modified version of PTFE that maintains the exceptional chemical and heat resistance properties of PTFE, but has a significantly lower melt viscosity. TFM™-1600 has a lower coefficient of friction that provides better creep resistance than PTFE.
TFM1600 Features:
Very good free-flowing properties
Improved particle coalescence
Dense polymer structure with reduced void content
Low permeability
Substantially lower deformation under load (“cold flow”)
Good electrical and mechanical properties
Increased modulus of elasticity
Good weldability
Excellent chemical inertness
Low friction behaviour
TFM 1600, is a kind of hot sealing material which used for industry valves. It is a modified PTFE that maintains the exceptional chemical and heat resistance properties of conventional PTFE, but has a lower melt viscosity. Offers the advantage of smoother surfaces, reduce deformation under load
