Black/grey DuroStone,Soldering sheet supplier In china

Description 

Durostone is a glass fiber compound which designed to satisfy different needs on painting of PCB ,and its a heavyduty glass fiber reinforced plastic which offers extreme strength and excellent electrical, thermal and chemical properties. Durostone is manufactured by using Polyester, Vinylester, Epoxid- and modified Epoxy resins combined with glass fibers.

It can keep it’s mechanical strength,smoothness and original color when continuously used under the temperature of 280°c (max. working temperature below 385 degree 10~20sec). It’s applicable in ROHS applicance production line under high temperature continuously.this can improve PCB quality during the wave soldering to prevent pollution of gold_finger or contract hole caused by human contact.

1)High mechanical strength

2)High temperature resistance( operating temperature up to 384 degree)

3)Good mechanical strength (low density)

4)Light weight

5)Low thermal conductivity
6) Less distortion

7)High mechanical strength.10)Long life

8)Superior dimensional stability.

9)Resistance to chemical corrosion

10)low water absorption

11)easy processing and excellent physical properties.
