TR90NZ 眼镜架料 抗冲击PA12 Grilamid 良好韧性 工程工具 

Grilamid TR90 NZ 是一种抗冲击改性透明聚酰胺 12 （PA 12） 牌号。具有非常高的弯曲疲劳强度，即使在低温下也具有良好的韧性和良好的尺寸稳定性。即使在低温下也具有抗冲击性，具有良好的耐化学性、抗紫外线性、耐水解性和耐应力开裂性。与标准聚酰胺相比，吸湿性低，吸水率低，热变形温度高，易于加工。可以用透明和不透明的颜色着色。显示出可逆的热致透明度，即在从室温加热到约70°C的过程中，透明度不断降低，而在80°C时，材料是不透明的。适用于注塑成型和挤出成型加工。用于汽车应用，如燃料和压缩空气系统、内部和外部、电器和设备、连接器、液压和气动、移动电话和其他便携式设备、医疗设备、工程工具和眼镜架。符合 REACH、RoHS 和 WEEE。

Grilamid TR90 NZ is an impact modified, transparent polyamide 12 (PA 12) grade based on aliphatic and cycloaliphatic monomers. Possesses very high flexural fatigue strength, good toughness even at low temperatures and good dimensional stability. Provides impact resistance even at low temperatures, good resistance to chemicals, UV, hydrolysis and stress cracking. Offers low moisture absorption, low water absorption compared to standard polyamides, high heat distortion temperature and easy processability. Can be colored in transparent as well as opaque colors. Shows reversible thermotropic transparency i.e. transparency continuously decreases during heating from room temperature to about 70°C and at 80°C the material is opaque. Is suitable for processing by injection molding and extrusion. Used in automotive applications like fuel- and compressed air systems, interior & exterior, electrical appliances and equipment, connectors, hydraulics & pneumatics, mobile phones and other portable devices, medical devices, engineering tools and spectacle frames. Complies with REACH, RoHS and WEEE.
