Miracle Materials
The stuff of Urban Legends? I have run across materials that people have invented, but are not widely known, for whatever reason. I will list them here, as I learn
of them. If you want to hear more about it, contact us, and we will get you whatever information is available. I do NOT warrant any of this information to be true, but generally, I am able to secure samples
of one kind or another. I found these to be interesting. Even more so if they can solve a problem for you. Write to me if YOU have a special material. Better yet, let me know if you have an
application. |

H igh Temperature
The story went like this: "A friend of mine needed a high temperature material for use in the casting industry for core molds, to take 800° F. My
friend, who is very good with silicones and urethanes, put mixed up some material and it worked. It was submitted to an oxy-acetylene torch, and did not
melt! This suggests that it was taking closer to 5,000 ° F than 800° F! That's not all. The finish was like a styrofoam cup, but firm, though you could dent it with your
fingernail. The next version was hard and black, and shiny. The inventor tells me that he can make it flexible as well, with substantially the same properties. For a
few bucks, he'll even make you a sample!
UPSIDE: Very high temperature resistance
DOWNSIDE:
The expense of getting the physicals tested has kept him from getting this information. We do not know it's other properties yet. |

So und Deadening
The inventor claims that he noticed that certain oil pans were make in two layers, with sound deadening material between them, which were then welded together. He determined to make a material that could be
sprayed on, which would perform as well or better than this, so the pan could be made in one piece without assembly. He did it. He tested it,
and the sound deadening effect was comparable. The cost was much lower.
UPSIDE:
Excellent sound deadening, using old principles in a spray form.
DOWNSIDE:
There appears to be no way to protect this. So why promote it? Any ideas?. |

Abras ion Resistance
It is a dusty additive for plastics like HDPE or PUR or UHMW, to increase the wear resistance considerably. While UHMW has great
wear resistance without additives, it is far better with it. HDPE acts like UHMW when it has this additive in it. There is some good test data on it. Try some! I'll get you a sample!
UPSIDE:
Very high abrasion resistance
DOWNSIDE: The material is still made in small batches. He needs some
applications requiring wear resistance, to prove it out. |

Incr edible Mechanical Strength .
It is a kind of fiberglass, except that it is molded from thermoplastic, like either recycled polyethylene or polypropylene. The terrific strength/stiffness comes from the glass reinforcement of up to 40% by
weight, with glass fibers up to 2 inches long! I have seen this process and it is amazing in it's simplicity. The inventor can mold parts reinforced
or unreinforced on aluminum tooling. Most parts are quite large, and not too deep, like picnic tables, or wheel barrows. He is IN business, molding now. 1500 big
parts per day. It is strong, cheap fiberglass!
UPSIDE: Very high tensil, flexural, compression strength, at a low price.
DOWNSIDE:
Large tools, even in aluminum are costly. Minimum run is around 1500 to 2000 pieces. Material can be decorated with in-mold graphics, but
cannot be easily painted because it is a polyolefin base. |
