Structure – Substrate leh Thickness tihchak

Substrate hian framework angin hna a thawk a, a bulpui berah chuan bending resistance leh tear strength a tichiang a ni.

Pure PTFE film hian flexibility tha tak a nei a, mahse mechanical strength a nei tlem hle – stress repeated hnuaiah a tearing awlsam hle. Glass fiber reinforced PTFE hian tensile strength, tear resistance, leh creep resistance te nasa takin a ti tha a, dynamic bending scenario atan chuan duhthusam a ni.

Thickness pawh a pawimawh hle. 0.13mm hian dividing line hna a thawk a ni. Tape 0.13mm aia thim zawk te hi a flexible a, mahse a chakna a hniam a, compression leh stretching nawn leh hnuah microcrack siam a awlsam hle.

Thurawn : Dynamic equipment tam zawk tan chuan 0.18mm thickness leh glass fiber reinforcement hi standard choice a ni.

Continuous band sealer (minute khata cycle 30-60 vela thawk) ang chi high-cycle application-ah chuan heating element vel a tape bending radius hi design parameter pawimawh tak a ni. Bending radius 5mm aia tlem chuan local stress chu 15mm radius nena khaikhin chuan 300% aia tam a tipung a, crack initiation nasa takin a ti chak hle. Chutiang tight-radius application atan chuan glass fiber reinforced PTFE tape, woven construction nei (film-based tape ai chuan) hman hian flex life chu a let 5-10 in a tisang thei a ni. Tin, tape backside finish smoother zawk nei te hian bending laiin internal friction a siam tlem zawk a, hei hian hahna a ti tlem zual sauh bawk. Field data atanga a lan dan chuan 0.10mm pure PTFE film tape atanga 0.18mm glass fiber reinforced tape a inthlak chuan high-frequency sealing equipment ah kar 2 atanga thla 6 aia rei thlengin service life a ti rei thei a ni.

Adhesive dik tak chu thlang rawh

Adhesive hian tape chu hmanrua nen a thlunzawm a – hei hi dynamic service life tichhe thei thil pawimawh tak a ni. Silicone pressure-sensitive adhesive hi dynamic high-temperature environment atan chuan duhthlan tur tha ber a ni.

Engvangin nge silicone hian bending application atan hnehna a chang:

• Bending leh vibration repeated pawh crack awm lovin a tuar thei

• Hot leh cold cycle inthlak danglamnaah a insiamrem thei

• Flex cycle sang tam tak hnuah pawh adhesion a vawng reng

Aokai PTFE ’s in-house testing atanga a lan dan chuan silicone adhesive tape te hian bending cycle 10,000 hnuah an initial peel strength 90% aia tam an vawng reng a, acrylic-based tape te erawh chuan cycle 5,000 chhungin 50% thleng an hloh thung. Nitin darkar 16 chhunga hmanraw hman tan chuan he danglamna hi thla tam tak chhung service life extra a ni.

Reciprocating sealing bar-a hman PTFE tape (eg, vertical form fill seal machine) tan chuan adhesive hian ‘cold flow’ – pressure hnuaia zawi zawiin a inthlak danglam thei bawk. Silicone adhesives quality tha lo chu rei tak hman hnuah tape edge hnuai atangin a chhuak thei a, chu chuan product emaw sealing bar-ah adhesive residue a siam thei a ni. Thermosetting structure nei crosslink-density sang tak silicone adhesives te hian 250°C ah pawh dimensional stability an vawng reng thin. High-frequency bending application atana PTFE tape thlan hunah ‘shear adhesion failure temperature’ (SAFT) leh ‘holding power’ chungchanga data dil tur a ni – 260°C aia sang leh 200°C-a darkar 24 aia tam value chuan adhesive system nghet tak a nih thu a tarlang.
