新能源汽车电池用热缩管的阻燃等级要求

 最近新能源汽车电池常用热缩管有两种,带胶双壁管单壁热缩管。要求材料高度阻燃,等级VW-1的热缩管,阻燃等级已经成为兴能源行业的硬性指标。
燃料电池汽车、混合动力汽车、氢能源动力汽车和太阳能汽车等新能源汽车都是依靠电池蓄电。电池作为主动力能源不可避免的会产生大量的热量,热缩管是否达到阻燃等级不仅影响了电池正常工作和寿命,对汽车安全性也会产生影响。
应满足以下三点:
1.VW-1测试标准实验规定试样保持垂直用试验用的喷灯(火焰高度125mm热功率500W)燃烧  15秒钟然后停止15秒钟反复5次。余火焰不可超过60秒钟。
2、试样不可烧损25%以上。
3、垫在底部的外科用棉不可被落下物引燃。

注意,这里一定是垂直燃烧,否则即视为不达标。
在能源制约、环境污染等大背景下,我国政府把发展新能源汽车作为解决能源及环境问题、实现可持续发展的重大举措,各汽车生产企业也将新能源汽车作为抢占未来汽车产业制高点的重要战略方向。我公司作为配套企业,亦不断推陈出新,满足各类质量要求。
我公司供应阻燃热缩套管,欢迎前来咨询。
