PTFE High-Temperature Tape hmanga temperature & Viscosity tihziaawmna a ni

PTFE high-temperature tape siamtu professional Jiangsu Aokai New Materials chuan oven hman nawn leh hnua PTFE tape performance inthlak dan a sawifiah a.The attenuation of temperature resistance and holding viscosity mainly lies in the adhesive layer , rather than the PTFE substrate. PTFE substrate molecular structure hi a nghet hle a, 260°C hnuaiah pawh a upa thei lo. Chumi danglamna chu, silicone ang chi high-temperature adhesive layer te hian repeated heating hnuaiah thermo-oxidative aging an tawk a, hei hian a tawpah chuan PTFE high-temperature tape service life a tichiang a ni.

1. Temperature Resistance chungchanga Attenuation Law

Normal oven temperature (≤ 260°C) Adhesive hi a upa zawi zawi a, a nominal temperature resistance chu kum tin a tlahniam zel bawk. A rawngbawlna hun rei tak chu kum 1–3 vel a ni.

Slight over-temperature (260–300°C) Adhesive aging chu nasa takin a chak a, service life pawh kum engemaw zat atanga kar tlemte chauh ah nasa takin a tlahniam a ni.

Severe over-temperature (>300°C) Adhesive hi a nem a, a chhe a, carbonize pawh a nei rang a, chu chuan viscosity a hloh nghal a, hun rei lote chhungin a peel off nghal bawk.

Thermal cycling tih nawn fo hian a lum leh vawt chak lutuk hian thermal stress impact a siam a, chu chuan adhesive leh substrate inkarah micro-delamination a siam a, temperature resistance a hlawhchhamna a ti chak bawk.

2. Attenuation Law hmanga Viscosity vawn dan

Hnathawh dan pangngaia tlahniam zawi zawi Rated temperature range chhungah hian oven cycle a san chuan holding viscosity a tlahniam zauh zauh a, adhesive layer chu hun kal zelah a khauh a, a ti chhe vek bawk.

Over-temperature leh harsh conditions hnuaia Sharp attenuation Vawikhat a lum lutuk emaw, chemical media-a a awm emaw chuan, a lum hnuah bonding strength chu 50% aia tam a tlahniam thei.

Critical point of functional failure Tape chu a lan danah a awm reng a nih pawhin a non-stick leh gripping property te chu a hmain a chhiat thei a, a hun taka thlak a ngai a ni.

3. Performance Degradation ti chaktu thil pawimawh tak tak

Adhesive type Silicone pressure-sensitive adhesive hian 260°C thlenga temperature resistance a nei a, acrylic adhesive (120–150°C chauh) aiin a sang zawk hle.

Substrate structure Fiberglass-reinforced PTFE tape hian dimensional stability tha tak leh thermal creep resistance tha tak a pe a, pure PTFE film tape aiin service life a rei zawk hle.

Hnathawhna hmun Oven hnathawh laiin friction a awm a, chubakah solvent emaw flux emaw nena inhnaih chuan physical leh chemical degradation a tizual ang.

Material quality Tape quality hniam tak takte hian temperature resistance dik lo taka chhinchhiahna an nei fo thin a, an upa nghal vat a, oven cycle tlemte chauh an hman hnuah an chhe thin.

4. Degradation tihziaawmna tura hman dan tur rawtna

Temperature control khauh tak Hun rei tak chhunga hnathawh chhunzawm zel tur temperature chu 260°C hnuaiah dah la, temperature sang lutuka hnathawh loh tur.

Model thlan dan dik tak Silicone-based PTFE tape quality sang tak thlang la, SMT leh a ang chi process-ah cycle 500 chuang a tuar thei.

Standardized application Lamination hmain bonding surface chu absolute ethanol hmangin uluk takin silfai la, chutiang chuan uniform stress leh tight fitting a awm theih nan.

Process optimization Adhesive layer-a thermal stress chhiatna tih tlem nan a tul lo taka thermal shock frequency tihtlem.

A dahna dik Tape hman loh chu hmun sealed, thim, lum leh vawt takah dah la, adhesive chu a tar hma loh nan.

A hun taka thlak Coating peeling, surface carbonization, edge warping emaw non-stick performance hloh emaw a awm veleh thlak nghal a ngai a, chutiang chuan stable production a awm theih nan.
