What is Norsorex used for?

NORSOREX ® – the unique polymer Advanced recipes and compounding give materials with high wet grip, high abrasion resistance, high tear strength and low rolling resistance. A perfect combination for high performance wheels in the tire industry.

What is Polynorbornene used for?

Polynorbornene is used mainly in the rubber industry for anti-vibration (rail, building, industry), anti-impact (personal protective equipment, shoe parts, bumpers) and grip improvement (toy tires, racing tires, transmission systems, transports systems for copiers, feeders, etc.)

What is norsorex APX?

Norsorex® APX is a high molecular weight, pure hydrocarbon-based polynorbornene polymer (C7H10)x with a very large surface area and a high a affinity to all sorts of liquid hydrocarbons.

What is polynorbornene rubber?

Polynorbornenes or polynorbornylenes (PNRs) are unique commercial elastomers with high glass transition temperatures (> 310K)1, outstanding thermal stability, excellent optical transparency, high friction coefficient, and low dielectric constant. They are produced via ring opening polymerization of norbornene.

How do Happy Sad balls work?

The Happy/Sad balls demo is a basic and straightforward way to demonstrate elastic and inelastic collisions. The “happy” ball is firmer and results in an elastic collision with a surface, while the “sad” ball is squishier and results in an inelastic collision with a surface.

Is neoprene a bouncy?

In contrast, neoprene, which has a low cross-link density, has a reversible elongation of 500% and a glass transition tempera- ture (T,) of -42 OC. The T, is the temperature below whicb a flexible polymer becomes rigid, and therefore the neoprene ball will not bounce a t temperatures below -42 “C (6).

What is the difference between the happy and sad balls when they collide with the table?

The happy ball has a lower hysteresis so it will dissipate more energy in the collision with the table, causing it to bounce relatively high. The sad ball has a higher hysteresis so it will dissipate less energy in the collision with the table, causing it to barely bounce, if at all.

Why are bouncy balls so bouncy?

Store-bought bouncy balls are made of rubber, another material that is made up of polymers. When the bouncy ball is stretched, these polymer chains uncoil and straighten. When released, the chains coil back up again. This makes the material stretchy and bouncy.

What are bouncy balls called?

The ubiquitous bouncy ball, or “superball,” is an engaging child’s toy that has endured for more than 50 years.

What is the most bouncy ball?

Mega Bounce XTR
The Mega Bounce XTR is the bounciest ball of them all! Drop it onto a hard surface and it’ll bounce 85% of its original height (a basketball manages a measly 56%)! Throw it down as hard as you can and watch it soar way higher than a 2 story building…it really is MEGA!

What is the science behind making bouncy balls?

The Science of Bouncy Balls Making a bouncy ball is an example of a chemical reaction. This reaction happens between the Borax and glue. The Borax is the cross-linker for the glue’s polymer molecules. This creates chains of molecules that stay together when your child plays with the ball.

What is a crazy ball?

The crazy ball is made up of polyurathene (PUT) and polyvinyl chloride (PVC). The latter can be made as elastic as a rubber band or as rigid as a car tyre. The crazy ball is made up of soft but rigid PVC. <

Is the Norsorex powder insoluble in water?

NORSOREX® APX is a special polymer with very high affinity for hydrocarbons and, since it is hydrophobic, it is also insoluble in water. NORSOREX® APX can be used in free powder or pad form (sealed bags containing the powder).

What is the Tg of Norsorex hydrocarbon gel?

Norsorex® has a Tg of 37 °C that contributes to its remarkable damping properties in shock, vibration, and sound control applications. 24 Due to its low polarity and high molecular weight, Norsorex® can absorb up to 10 times its dry weight in hydrocarbons, forming a gel that maintains reasonable mechanical properties.

Which is the best way to use Norsorex APX?

1. Application Method: NORSOREX® APX is a special polymer with very high affinity for hydrocarbons and, since it is hydrophobic, it is also insoluble in water. NORSOREX® APX can be used in free powder or pad form (sealed bags containing the powder).

How is Norsorex used in oil spill cleanup?

Due to its low polarity and high molecular weight, Norsorex® can absorb up to 10 times its dry weight in hydrocarbons, forming a gel that maintains reasonable mechanical properties. Accordingly, it has found some application for oil spill cleanup.
