Quelle est la différence entre le PTFE et le 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

• Faible perméabilité 

• Substantially lower deformation under load (“cold flow”) 

• Good electrical and mechanical properties 

• Increased modulus of elasticity 

• Bonne soudabilité 

• Excellente inertie chimique 

• 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
