Zawhna zawt rawh

Selection a nih hunah PTFE high-temperature cloth , a lei tam zawk chuan thickness leh coating quality lam an ngaihtuah ber. Mahse PTFE layer hnuaiah hian parameter pawimawh tak thup a awm a, chu chu warp leh weft density a ni . fiberglass substrate

Density hian yarn te chu engtiang chiahin nge tight taka an pack tih a sawifiah a ni. Engkim a nghawng vek – tensile strength, tear resistance, coating adhesion, flexibility, leh surface smoothness te a nghawng vek a ni. A dense lutuk a, puan chu a tear strength tha lo avangin a khauh ta a ni. Loose lutuk, leh pinholes te pawh dimensional stability chak lo tak nen a lang thei bawk.

Aokai PTFE hian production run sang tam takah fiberglass density a ti tha hle. He guide hian density hian key property a nghawng dan a sawifiah a, i application atana balance dik tak i thlan theih nan a pui bawk.

Mechanical chakna & Dimensional Stability a ni

1. Tensile chakna (Tensile) chakna

Density Level a ni	Tensile chakna a nei	Mechanism hmanga thil tih dan
Density sang zawk a awm	A tlangpuiin a sang zawk	Yarn tam zawk chuan unit zau zawngah load an share thin
A sang lutuk	Plateau emaw a tlahniam emaw thei	Intensified yarn crimp hian fiber hmanna a tihhniam a; puan a tikhauh

Practical note: Tensile strength sang ber mamawhna atana hman tur (eg, tension sang hnuaia conveyor belt zau tak siam) tan chuan density moderate-to-high neih tum ang che. Mahse extreme density hi pumpelh la, chu chuan dynamic load hnuaiah a hmaa hahna a thlen thin.

2. Mittui chakna – Inverted U-Curve

Tear strength hi density-in a nghawng dan indicator thiam ber a ni. PTFE coating hnuah polymer resin hian woven yarn te chu a hmunah a lock thin. Inzawmna hian inverted U-shaped curve a zui a :

Density Level a ni	Mittui chakna	Mechanism hmanga thil tih dan
Density hniam tak a ni	Rethei	Yarn inkar gap lian tak tak hian yarn a ti chhe zel a; yarns te chu a cluster thei lo
Density tlemte a awm	A tha ber (peak) 1.1.	Yarns te chu tearing stress hnuaiah tlem a slide a, a bunch khawm a, force insem turin
Density sang lutuk	Rethei (a tlahniam nasa hle) .	Yarns chu coating + tight weave hmanga fully immobilized; stress chu yarn hrang hrangah a innghat → brittle rupture

Key takeaway: Tear strength sang ber chu density sang ber ni lovin moderate density ah a thleng thei. Hei hi counterintuitive a ni fo thin.

Aokai PTFE hian fiberglass substrate a pe a, density chiang taka control theih a ni. Tear-critical application (eg, roller conveyor-a conveyor belt-a ding fo thin) atan chuan tear resistance tihpun nan density moderate (a tlangpuiin 18-20 ends/cm) kan rawt a ni.

3. Dimensional Stability & Anti-Warp hnathawh theihna

Density ziarang a ni	Dimensional Stability a ni	Nghawng
Warp/weft density inthlau tak a ni	A tha lutuk	Thermal shrinkage leh internal stress te chu a sir lehlamah a inmil tir a; temperature sang takah warping a veng thei
Density inthlauhna lian tak a awm	Rethei	Thermal shrinkage inmil lo → lumna hnuaia puan tihchhiatna nasa tak
Compact a ni a, a density sang hle	Tha fawr	Substrate hian yarn contraction a tikhawtlai a ni

Thurawn: Temperature sang tak, dimensional accuracy dik tak mamawh (eg, heat-sealing gaskets, laminating pads) atan chuan balanced, moderate-to-high density substrate thlang rawh.

Coating penetration, Adhesion & Surface te a ni

1. Permeability & Mechanical Anchoring chakna hmanga thil tih theihna

Density Level a ni	PTFE penetration a ni	Coating Adhesion a awm bawk
Density hniam tak a ni	Deep penetration – emulsion hi pores lian tak takah a luang chhuak thin	'rivet ang chi' mechanical interlock → bonding tha tak a siam
Density sang tak a ni	Hindered – resin hian fiber bundles a luh theih nan a bei nasa hle	'surface-coated yet inner-dry' structure → peel resistance tha lo awm thei

Trade-off: Low-density hian open meshes (chuti lo chuan pinholes a lo chhuak) fill turin coating pass tam zawk a mamawh a ni. High-density hian full penetration a awm theih nan optimized dipping parameters a mamawh a ni.

2. Surface Smoothness & Non-Stick hmanga hnathawh theihna

Density Level a ni	Surface Coating zawhah	Best For
Density sang tak a ni	Woven texture tha tak, smooth finish, premium non-stick, tihfai awlsam tak a ni	Demolding hmanna standard sang tak (eg, composite molding, ei tur chhuahna) .
Density hniam tak a ni	Weave indentation hrang hrang a la awm	Conveyor belt-ah chuan textured surface hian contact area a tihtlem a, boruak tang a chhuah tir a, workpiece a slip loh nan a hmang bawk

3. Voltage & Pinhole Ratio a tuar thei

Denser base cloth hian pores fin zawk, uniform zawk a nei a, pinhole-free surface neih theih nan coating thinner a ngai a – dielectric breakdown strength rintlak a nih theih nan.

A hman dan tur: Electrical insulation hmanna atan chuan high-density substrate hi a tha zawk.

Flexibility & Dynamic Fatigue laka inven theihna

Density Level a ni	Flexibility a awm thei	Flex Fatigue Nunna hi a ni	Best For
Warp/weft density hniam tak a awm	A tha hle – yarn te hi interlacing point-ah zalen takin an kal thin	Sei	Roller diameter te tak te-a inkhuh fo thin; component mumal lo tak takte tan custom demolding wrapping siam a ni
Density sang tak a ni	Rigid leh stiff tak a ni	Tawi	Static emaw low-flex emaw hmanga hman theih a ni

Flexing hnuaia high-density atana failure mechanism: Bending nawn leh hian yarn crossover point-ah friction leh extrusion nasa tak a thlen a, chu chuan coating cracking leh base fabric fracture a thlen thin.

Thurawn: Continuous high-speed flexing hnuaia hnathawk (eg, pulley te tak te-a conveyor belt, dynamic seal) tan chuan medium emaw low density emaw a tha zawk.
