PVDF PVDF Heat Shrink Tube Flow

Edit:Anji Jiahe Fluorourubber Made Products Co.,Ltd      Date:Apr 06, 2016

PVDF PVDF fluoro-plastics has the most strength and toughness, low coefficient of friction, corrosion resistance, ageing resistance, weather resistance, good resistance to radiation and so on. With polyvinylidene fluoride PVDF produces heat shrink tube with low temperature shrinkage, corrosion protection of soft, flame retardant, insulation feature. Widely used in all kinds of wire, solder, inductance of insulation protection, metal tube, Rod rust, corrosion, etc. PVDF PVDF heat shrinkable tubing process is as follows:

1, mixing: is a set formula of raw ingredients, and then use the mixer mixing produces polyvinylidene fluoride PVDF PVDF heat shrink tube need plastic pellets.

2, extrusion: PVDF particles into the mixer according to certain qualified pipe extrusion, extrusion of tube wall thickness, partial wall of polyvinylidene fluoride PVDF heat shrinkable tubing quality has a greater impact.

3, irradiation: PVDF pipes through the electron Accelerator for irradiation, pipe internal Crosslinking of polymer materials increased, becoming a net-like structure, are chemical bonds between chains and chain link, there is a strong interaction. Irradiation make joint process is hot shrink tube manufacturing in the most key of process, irradiation make joint degrees to right to manufacturing out qualified of hot shrink tube, irradiation make joint spent big, pipe on cannot expansion, industry commonly known as "as died has", make joint spent small, pipe also expansion not up, or cannot expansion to larger of multiples, easy split, and manufacturing and into of hot shrink tube of contraction force also enough, back shrink effect bad. For each product you want to develop an appropriate irradiation process parameters to produce qualified heat shrinkable tubing.

4, and expansion: irradiation make joint Hou of PVDF pipe, can with Preheat to high temperature with forces expansion of way, will pipe of caliber variable big, then quickly cooling to at room temperature, such expansion Hou pipe of shape also on stereotypes down has, this process main principle is, irradiation make joint Hou pipe of high points chain paragraph activity and temperature has great relationship, in must high temperature range within, chain paragraph activation, chain paragraph occurred stretch song, behavior of resistance is small, whole pipe on like a has elastic of network as, can was forces pulled big, So heated to this temperature range can be easily expanded up the tube. When the temperature rapidly, usually around room temperature, this activation will lose, chain extension curve resistance is large, retraction of internal stresses is not sufficient to overcome this resistance, so the State of nature, just keep after expansion.

5, packing: finished polyvinylidene fluoride PVDF heat-shrinkable tube after tube cutting and packaging printing can be sold.
