Relatively short polymer chains form crystals more readily than long chains, because the long chains tend to be more tangled. High crystallinity generally means a stronger material, but low molecular

In the molten phase, crystalline polymers closely resemble amorphous polymers. However, the real difference between the two exhibits itself during cooling. As crystalline polymers cool, small areas of

Crystallinity is one of the great divisions of the complete family of plastics. Crystalline olymers(those with a significant degree of crystallization) behave very differently than amorphous polymers(

Injection molding shrinkage is one of the properties when the material temperature drips. The rate of molding shrankage is needed in determining the final workpiece dimensions. The value indicates the

The two most important manufacturing methods with TPEs are extrusion and injection molding. Comperssion molding is seldom, if ever, used.

There are six generic classes of commercial TPEs. Styrenic block copolymers Polylefin blends Elastomeric alloys(TPE-v or TPV) Thermoplastic polyurethanes Thermoplastic copolyester Thermoplastic polyam

TPE materials have the potential to be recyclable since they can be molded, extruded and reused like plastics, but they have typical elastic properties of rubbers which are not recyclable owing to the

In order to qualify as a thermoplastic elastomer, a material must have these three essential characteristics.

​Thermoplastic elastomers(TPE), sometimes referred to as thermoplastic rubbers, are a unique class of engineering materials combining the look, feel and elasticity of conventional themoset rubber with
