Factory Directly Supply Hot Sale Steel Lined PTFE/PFA/ETFE/ECTFE Straight Pipe For Chemicals

1. The surface energy is low. The advancing contact angle (θd) of PTFE is 118°, the receding contact angle (θr) is 91°, and the contact angle (θ) is 104°, which is the largest of all materials, the larger contact angle, the smaller the degree of wetting, that is, the worse the wettability, the adhesive does not sufficiently wet the PTFE, so that it does not adhere well to the PTFE;

​2. The crystallinity is large and the chemical stability is good. The swelling and dissolution of PTFE are more difficult than the non-crystalline polymer. When the adhesive is applied on the surface of PTFE, it is difficult to cause mutual diffusion and entanglement of polymer molecular chains, with a strong adhesion.
