TR90NZ 眼鏡架料 抗沖擊PA12 Grilamid 良好韌性 工程工具 

Grilamid TR90 NZ 是一種抗沖擊改性透明聚酰胺 12 （PA 12） 牌號(hào)。具有非常高的彎曲疲勞強(qiáng)度，即使在低溫下也具有良好的韌性和良好的尺寸穩(wěn)定性。即使在低溫下也具有抗沖擊性，具有良好的耐化學(xué)性、抗紫外線性、耐水解性和耐應(yīng)力開(kāi)裂性。與標(biāo)準(zhǔn)聚酰胺相比，吸濕性低，吸水率低，熱變形溫度高，易于加工。可以用透明和不透明的顏色著色。顯示出可逆的熱致透明度，即在從室溫加熱到約70°C的過(guò)程中，透明度不斷降低，而在80°C時(shí)，材料是不透明的。適用于注塑成型和擠出成型加工。用于汽車(chē)應(yīng)用，如燃料和壓縮空氣系統(tǒng)、內(nèi)部和外部、電器和設(shè)備、連接器、液壓和氣動(dòng)、移動(dòng)電話和其他便攜式設(shè)備、醫(yī)療設(shè)備、工程工具和眼鏡架。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.
