BluPad is a premium press pad material
engineered for optimum control of the lamination process. Developed and improved with many years of use, research and
testing, it is one of the leading press pad materials in the world. Many quality
and cost conscious manufacturers of copper clad laminates, decorative and
industrial laminates as well as PCB manufacturers are
optimizing their laminating process with BluPad.
Construction - BluPad is made of specially treated cotton textile
fibers with heat resistance properties far superior to
equalization - BluPad provides an excellent
balance of pressure and temperature characteristics which ensure proper resin
flow. The result is optimum board quality and thickness tolerance. Improved
surface smoothness and a highly consistent product is achieved load after
materials - Because BluPad is made of specially treated cotton
fibers, it maintains its' properties under higher temperature
and pressure conditions better than cellulose based papers can. Suitable for
pressing polyimides and other high Tg
laminates. Customers use it up to 240°C.
transfer - properties are similar to those of cellulose papers
such as Kraft paper of the same weight. If closely to the same weight is
obtained, no change in heat cycle is needed. Evaluate optimum number of plies
for your own press cycle.
manufacturing - For most applications, 3 or 4 pieces of .015"
thick BluPad 215 HT on the top and bottom of each press opening provide the
proper rate of rise and pressure diffusion.
Number of uses - varies from user to user
and application to application. Decorative
Laminators use it up to 90 times,
Copper Clad Laminators
up to 10 times,ML Board
manufactureres 5-8 times. You determine the
optimum level for your process. There is no notable change in rate-of-rise
during the first 8-10 pressings.
sticking to press plates - Unlike
many other press pads, BluPad
normally does not stick to press plates. No costly release sheet is needed with
BluPad unless it is openly exposed to high humidity
Vacuum press -
Other materials that are used as press pads
such as silicone, kraft paper or chipboard can contain oils, adhesives or other
chemicals that can be released in a vacuum press. These agents can contaminate
the finished product. Also, they accumulate in the vacuum pump and can cause a
Static electricity build up
- Unlike silicone and some other press pad materials, there is
no dirt attracting static electricity buildup.
Less dust - BluPad generates less dust that Kraft
and white cellulose papers. Silicone pads pick up resin dust and must be cleaned
Less inventory -
Because BluPad is used a number of times, less space is needed for inventory and
less paper needs to be recycled.
reduction - With multiple reuses of BluPad you save money, and you will make a better
product. Now that's money in the pocket.
