耐水解性

Hydrolysis Resistance 

廣欣材料SPS與其它聚酯類樹脂以及PA類樹脂相比較，具有更加優(yōu)良的耐水分解性，其特性與PPS接近。 

with polyester-based resins and polyamide-based resins,  exhibits superior hydrolysis resistance, and boasts properties close to those of PPS. 

耐化學(xué)藥品性

Chemical Resistance 

廣欣材料SPS不易被各種的酸、堿所腐蝕，對于與汽車環(huán)境相關(guān)的油類，冷凍液等也具有優(yōu)良的耐腐蝕性

 is also highly resistant to penetration by various types of acid and alkali, and it also has excellent durability towards oils and antifreeze which are used for automobile. 

低比重

Low Specific Gravity 

廣欣材料SPS在工程塑料中屬于比重Zui小的種部類。與其它工程塑料相比較，在零件的輕量化和低成本化方面具有優(yōu)勢。 

 has one of the lowest specific gravities among all engineering stics. Compared with other engineering stics, it is advantageous in terms of reduction of parts in weight and cost. 

耐熱性

Heat Resistance 

長期耐熱溫度為130℃,熱變形溫度為250℃。而且廣欣材料SPS的熔點(diǎn)為270℃, 也不易吸潮，耐受焊錫焊接的能力就不言而喻，而且具有耐回爐焊接處理的能力。因此，在可望用作電氣電子零件的SMT類芯片IC零件和接插件材料的運(yùn)用上得到展開。 

The long-term heat resistance temperature is 130°C and the heat distortion temperature is 250°C.Furthermore, because  possesses a melting point of 270°C and moreover does not readily absorb moisture, it is not only for wave soldering but also reflow soldering in terms of heat resistance. Accordingly,  can be used for SMT chip parts and connectors 

電性能

Electrical Properties 

廣欣材料SPS的介電性能在工程塑料當(dāng)中，與氟素樹脂接近，具有極低的介電損耗和介電常數(shù)。而且，從低頻領(lǐng)域到高頻領(lǐng)域，在很寬的溫度領(lǐng)域都具有穩(wěn)定的介電性能，適合于用作高頻零件材料其運(yùn)用可以向高頻零件領(lǐng)域發(fā)展。 

Among engineering stics, 's dielectric properties are close to those of fluororesins in terms of dissipation factor and dielectric constant. Moreover, is suitable for high frequency components since it has stable electrical properties under wide range of frequency and temperature. 

尺寸穩(wěn)定性

Dimensional Stability 

廣欣材料SPS的成型部件具有在注塑樹脂的流動方向(MD)和垂直方向(TD)上的收縮率差很小的特點(diǎn)，與其它的GF增強(qiáng)結(jié)晶性樹脂相比較，具有良好的尺寸穩(wěn)定保持性能。 

 has small difference in mold shrinkage between flow direction of molten resin (MD) and transversal direction (TD), it exhibits good dimensional performances compared with other glass fiber reinforced crystalline resins 

優(yōu)良成型性

Processability 

廣欣材料SPS可以通過標(biāo)準(zhǔn)型號的注射成型機(jī)進(jìn)行加工成型。具有接近于LCP的高流動性。此外，因過熱歷史而引起較的變質(zhì)非常小劣化，也因容易粉碎，因此而具有優(yōu)良的回收再利用性能。 

can be molded on a standard specification injection molding machine, and it possesses high flow properties close to those of LCP. In addition, degredation due to thermal history is minimal, and  is easy to grind. For these reasons,  is easy to recycle.
