产品详细信息

透明琥珀色PEI 1000

优点

长期耐热性
由于玻璃化转变温度高达217°C，在高温下物理和机械性能具有优异的稳定性。相对热指数（RTI）高达180°C

刚度
在可用的替代品中，具有卓越的强度和非晶态热塑性塑料，可预测的刚度和强度高达200°C。未填充的透明等级在强度上与其他具有不透明填料的热塑性塑料相同
。填充等级具有极高的尺寸公差能力

环境应力和抗裂性
与大多数其他非晶态热塑性塑料不同，ULTEM树脂在暴露于汽车和飞机流体、脂肪族碳氢化合物、醇、酸和弱水溶液中时保持强度并抵抗应力开裂
。根据NBS烟雾演变测试，产生极低的烟雾，燃烧产物的毒性不超过木材

Benefits

LONG-TERM HEAT RESISTANCE
Excellent stability of physical and mechanical properties at elevated temperatures thanks to high glass transition temperature of 217 °C. Available with relative thermal indices (RTI) up to 180 °C

STRENGTH AND STIFFNESS
Outstanding strength and amorphous thermoplastic among the available alternatives, with predictable stiffness and strength up to 200 °C. Unfilled, transparent grades are equal in strength to other thermoplastics with opacifying fillers.

DIMENSIONAL STABILITY
Among the most dimensionally stable thermoplastics available, offering predictability over a wide temperature range. Filled grades offer exceptionally high-tolerance dimensional capabilities.

ENVIRONMENTAL STRESS & CRACKING RESISTANCE
Unlike most other amorphous thermoplastics, ULTEM resins retain strength and resist stress cracking when exposed to automotive and aircraft fluids, aliphatic hydrocarbons, alcohols, acids, and weak aqueous solutions.

FLAMMABILITY, SMOKE GENERATION AND TOXICITY
Inherent flame resistance without additives in most grades – exceptionally difficult to ignite, with a limiting oxygen index (LOI) of 47%, meeting UL94 V0 specifications in sections as thin as 0.41 mm. Generates extremely low smoke per the NBS smoke evolution test, with products of combustion no more toxic than those of wood.

PROCESSABILITY
Can be extruded, thermoformed, extrusion blow molded and injection molded, and flowability permits long flow lengths down to 0.2mm thick using conventional injection molding equipment.
