产品描述

TR90材质的眼镜与尼龙材料比较，TR-90材质的镜框具有如下特点：

1、重量轻：约少与板材框重量的一半，是尼龙材料的85%，减少鼻梁、耳朵负担，使佩戴更加轻便舒适。>125kg/m2弹性，以有效防止在运动中因撞击而对眼睛产生的伤害。

2、色彩鲜艳：比普通塑料框架色彩更鲜艳出色。

3、耐撞击：是尼龙材料的2倍以上，ISO180/IC：

4、耐高温：短时间内可耐350度的高温，ISO527:抗变形指数620kg/cm2。不易熔化和燃烧。镜架不易变形不易变色，使镜架佩戴更长久。

5、安全：无化学残留物释放，符合欧洲对食品级材料的要求。

TR90的材料比其他pc，cp等眼镜架材料要贵得多，而且制作工艺也比较严格，所以TR90眼镜架的价格要比其他的要贵好几倍。

TR90注塑工艺：

TR90成型加工要求说明：

1. 充分干燥到含水率小于0.1%非常重要，否则注塑挤出成型出来的制品就会发白（气白雾）、发黄、发泡、银文，脆裂，外表难看，机械性能变差，且原料损耗大；

2. 干燥：使用除湿干燥机（把潮湿的空气干燥后，再送如干燥机）用干燥的空气带走原料中的水分，这样成型的制品外观、性能合格；如果没有除湿干燥机，请选择天气晴朗、空气湿度小于50%时才生产；

3. 如果干燥充分、塑件还是发白，请提高料筒的注塑温度，使原料充分塑化；

判断：塑件一定要同原料的颜色、透明度一样，说明你的注塑工艺正确。

注塑工艺

1.干燥：80℃以下（不要超过80℃） 干燥4－8小时
