玻璃\矿物PPS 6165A6---Linear PPS and crosslinked PPS
Compared with the crosslinked PPS, the linear PPS represented bydurafide has the following characteristics.
High tensile and impact strength, excellent toughness.
It can be used in electronic field and fuel cell parts with highrequirements.
Excellent thermal stability, easy processing.
The welding seam has high strength and excellent secondaryprocessing performance such as thread and pressing.
High whiteness, dyeable.
Durafide is not only used in various electronic components suchas lamp holder, water pump, PCU (integrated power control unit) ofhybrid electric vehicle and electric vehicle, but also used infunctional components of office equipment, audio-visual equipment,etc. it also makes full use of the characteristics of materials inthe application of kitchen and bathroom components such as hybridfaucet and water heater.
Due to its excellent strength and heat resistance, durafide isexpected to be a substitute for metal.
玻璃\矿物PPS 6165A6--PPS成型条件:
1 预干燥
DURAFIDE®吸湿性较弱,但为了改善成型品外观并防止流涎,仍要进行140℃×3小时或120℃×5小时的预干燥。
为了防止干燥时产生搭桥(bridging)现象,建议根据等级的具体情况进行105℃×5小时的预干燥。
由于碳纤维吸湿性强,碳纤维增强等级(2130A1、7140A4等)尤其需要进行预干燥。
就自然色而言,为了获得更加稳定的色相,应使干燥条件保持统一。
2 注射成型机
为了防止滞留变色,应选用1次注射重量与成型机容量较为均衡的注射成型机。
可选用普通的开式喷嘴,但为了防止流涎有时也可使用截止阀。料筒和螺杆zui好选用耐摩擦而又耐腐蚀的材质。普通的标准料筒和螺杆有时会出现明显的腐蚀和摩擦,使用时应与成型机制造商充分协商。
3 成型条件
为了减少飞边,应调高机筒温度并降低注射压力。
