Phenolic Laminated Bakelite/durostone sheet

I. Material  Introduction

Durostone is a heavy-duty glass fiber reinforced plastic which offers extreme strength and excellent electrical, thermal and chemical properties. It can keep its mechanical strength, smoothness and original color when continuously used under the temperature of 280°c(max. working temperature below 385 degree 10~20sec).In addition, durostone have the advantage of easily machining, high intensity and can be easily machining into special mechanical parts.

II.  Durostone  Characters:  

1. Normal working temperature at 325 °C, operating temperature up to 384 °C

2. Less distortion, low thermal conductivity

3. Superior dimensional stability, Long life

4. High temperature resistance
5. Resistance to chemical corrosion

6. High mechanical strength

7.Good machinability (low density)

III. Durostone  Applications

1. Support thin baseboard or soft substrate circuit board

2. Carry an irregular shape solder pallet

3. Use multi-pak panel design to improve production efficiency

4. Prevent the deformation of the solder pallet during high temperature reflow soldering process

5. Smoothly surface, good endurance, applicable for Teflon spray painting

6. Avoid gold finger contamination by human contact

7. Protect bottom side SMT components during the wave soldering process

8. Prevent the deformation of the baseboard during the wave soldering process

9. Standardized the width of the production lines, eliminate the width adjustment of the production line

10. Prevent baseboard being contaminated by the overflow of tin

I. Bakelite Introduction

Bakelite sheet is  the combination of hard and high density material and impregnated paper using phenolic resin or fiber glass cloth and pressed under heat and pressure. This industrial laminate normally consists of fiber paper,cotton fabric, chemical fiber yarn and fiber glass,etc. When specific heat and pressure are applied to these layers,a chemical recation combines the layers into a high-pressure thermosetting plastic.

 II. Bakelite  Strength :

1.Outstanding machanical properties and resistance to oil.

2. Great dielectric properties.

3. Prominent electrical properties.

III.Bakelite  Applications

1.Parts for chemical equipment and general machinery.

2.Base plate,support and guard panel for  electric genertor.

3.Insulating parts for transformer, inverter, electric motor,distribution box, fixture board material,clamp plate for molds,high and low voltage wiring closet,as well as packing machine.

4.Mechanical mold,fixture material for PCB(printed circuit board)and ICT (in-circuit test),as well as forming machine, drilling machine and base plate for grinding,etc.
