PU发泡滚轮是采用超微细连续式发泡孔径为5-10?的技术制造，其能瞬间吸收物体表面水分，同时滚轮表面保持干爽并有运送、挤压、除水、断水效果、优越的吸水 |
性、韧性、耐摩擦性高可成倍的延长滚轮使用寿命，滚轮不需特别给水，在无水状态下也不会变干硬，始终保持滚轮外型圆度和弹性。
Haotaixing ROLLER---PU FOAMING ROLLER
An advanced polyurethane roller with ideal characteristics, our pu
roller has excellent water absorption ability, abrasion resistance
（no shedding）,and chemical resistance. Compared to standard pva
rollers, it stays soft and pliable without the need for pre-soaking
and has a higher temperature resistance （120℃）, making it perfect
for placement before drying ovens. Use of our pu roller will
increase the quality of your products and your production capacity
by improving quality control and saving time and effort.
特性：FEATURE：
不干硬、耐高温120度、超吸水性、韧性强、耐磨擦、不掉屑。
1. It is not necessary to supply water to the roller .It will keep
its roundness and flexibility without the need to supply water.
应用范围：APPLICATIONS：
电路板、内层板、IC脚架、 镀金制程、不绣 钢板、 液晶显示器、半导体晶圆、 玻璃等….是业界生产高精密产品的独门利器！
