Euismod collatio PBT vs. PPS ad film Capacitor Housings

I. Key proprietas differences

(I) Thermal resistentia

Pbt (Polybutylene TerePhthaase) : Melting Point ~ CCXXV ℃, limited longa-term usum infra CXX ℃.

PPS (Polyphenenene sulfide) : Melting punctum CCXC ℃, HD CCLX ℃, idoneam ad 180-220 ℃ continui servitium.

(II) Flamma retardancy

Pbt : Tardus, ardenti (UL94 HB).

PPS : Auto-exstinguunt (UL94 V, 0), Oxygeni Index XLIV%, ideal ad ignis-tutum applications.

(III) CUMATIUM Euismod

Pbt : High DECREMENTUM (1.5-2.2%), postulat post-fingunt sizing.

PPS : Minimum DECREMENTUM (0.2-0.8%), optimum dimensional stabilitatem.

(IV) Aqua effusio

Pbt : 0.07-0.09%, necessitates pre-siccatio.

PPS : 0.03%, minimal humiditas impulsum.

II. PBT characteres

Commoda :

Libratum mechanica vires humilis frictio et gerunt resistentia.

Bonum electrica velit (nisi summus frequency damnum).

Obsistens ad olea, alkalis et infirmi acida.

Limitations :

SCARIFATIO, sensitivo, pauper impulsum vires (requirit P. PBT).

Pauper hydrolysis resistentia.

III. PPS characteres

Commoda :

HORTUS MUSICUS : Stabilis at 200-240 ℃ longa-term.

Chemical inertness : Resistit maxime solvents (nisi fortes oxidizers).

Summus : 137MPA Tensile fortitudinem usque (GF-confirmat).

Flamma retardant : Meets Aerospace / Automotive Signa.

Limitations :

Intremini (modified Gradus sicut R-IV / G-VI sunt communia).

Excelsus sumptus (~ 2-3 × pbt).

IV. Applicationem missionibus

PBT :

Minimum sumptus electronics (iungo, virgas).

Automotive non-discrimine partes.

PPS :

High-temperatus capacitors, IC Trays.

Infestantibus eget environments.

Conclusio :
PPS excellit in altus-finem applications postulantes calor / flamma resistentia, dum PBT praebet sumptus-effective solutions ad generalem-ad usus. Material Electio pendeat a temperatus, budget et praecisione requisectis.
