Sometimes it is difficult to disperse black pigments on polymers,
resulting in agglomerates or clumps of pigment particles. These can
make for places where cracking can occur when the plastic is
stressed. This could be worse in the area of the ultrasonic
staking, since the polymer is likely somewhat weakened by the
welding process.
It is probably more likely that the black pigments could be
increasing the thermal properties of the plastic, so that the
material is heating faster causing more degradation than the other
colored parts. It may be necessary to adjust the ultrasonic staking
conditions for black parts with slightly lower amplitude, less
energy input or shorter duration.
Finally, there can be problems with the way the color is added.
Assuming that they are adding a color concentrate at the molding
machine, if they are adding too much or maybe adding a concentrate
that has an incompatible carrier polymer, like polyethylene or
nylon, they may not fully blend in the plastic, creating
contaminated layers of material.

As a follow-up to Friday’s blog post, Tips: Top 10 Flowers for Wedding Bouquets , I thought it might be fun to look a little deeper into the world of the #1 pick, the Rose, and what makes it so special.
As many of you know, Roses come in a rainbow of colors, all of which are said to carry a particular meaning — red = love, yellow = friendship and so on. To help you find the right color that best complements your personalities and style, here is a rundown of the top 7 colors and what they mean.
Red
Typically the star of Valentine’s Day, the Red Rose is undeniably romantic. Although it’s most notably associated with love and passion, this crimson color also symbolizes beauty, courage and respect.

Because it’s such a show stopper
on its own, Red is best paired with neutrals such as white, ivory
or cream, or, for the adventurous as heart, even black. Spring,
summer, fall, winter — doesn’t matter. This sultry color works well
at weddings all year ’round!
Orange
The bright and refreshing nature of Orange Roses make them the color of choice for ‘wow’ weddings. Orange is a symbol of desire and enthusiasm.

I absolutely love Orange for fall
weddings. It really embodies the beauty that surrounds you that
time of year.
Peach
Peach colored Roses are so unique! With a bright orange center fading into a soft pink at the tips of the petals, this flower is undeniably elegant. Peach symbolizes appreciation, sincerity and gratitude.

Peach is a fairly versatile color
that you can either dress up or down, depending on the style or
look you’re going for. Great for beach weddings or outdoor
celebrations in the warmer spring or summer months.
Yellow
So vibrant, bright and cheery — yellow roses are sure to put a smile on all your guests’ faces! Yellow is the color of friendship, joy, delight and promises of a new beginning.

Yellow is a perfect accessory for
spring or summer weddings, and it works well accompanied by accents
of blue, green, pink or purple.
White
White has always been associated with elegance and classic charm, which makes it one of the most popular choices for weddings. White Roses are a symbol or purity, youthfulness and hope for the future.

White is another versatile,

colors you like. Pair it with blue for a winter wonderland wedding,
or with black or silver for a chic, contemporary feel.
Pink
Pink Roses range in color from blush pink to fuchsia and magenta, so if you’re a pink fan, chances are you’ll find the perfect hue for your special day. Pink means happiness, tenderness, appreciation and pure love.
