Unique Properties

Heat Resistance

TPX has a high melting point in the range from 220°C to 240°C and a high vicat softening temperature. Hence, it can be used for high temperature application. However, as heat distortion temperature of TPX is almost same as that of polypropylene, the application under high-stress environment needs to be carefully considered.

Applications: Food Containers, Release Film for FPC, Rubber Houses, Release Paper foe Synthetic Leather, Animal Cage, LED Mold

Releasability and Non-compatibility

The surface tension of TPX (24mN/m) is very low and this value is the secondary lowest as compared to fluorine polymers. Hereby, TPX shows excellent releasability against various materials in hardening process of thermosetting resins (urethane, epoxy etc.) Furthermore, since TPX shows incompatibility against thermoplastic resins (PET, PP etc.) it is used to create a porous structure in PET or membranes.

Applications: Food Containers, Release Film for FPC, Rubber Houses, Release Paper foe Synthetic Leather, Resin Modification, LED Mold

Releasability and Non-compatibility

With the superiority of releaseability, TPX can hardly to be stained with food. The antifouling property is also a strong point of TPX.

The chart above shows the contrast among normal PP and TPX on food stain antifouling property. It is clear that compared to other materials, the containers made from TPX is hardly stained.

Transparency

Although TPX is a crystalline polymer, it exhibits excellent transparency (Haze:<5%) and light transmittance. Especially TPX is used for optical analysis cells because of the higher UV transmittance as compared to glass and other transparent polymers.

Applications: Food Containers, Animal Cage, Experimental Apparatuses

Chemical Resistance

Because of its stable C-C bonds, TPX has better chemical resistance as compared to polycarbonate and acrylic polymer. TPX basically shows excellent chemical resistance particularly against acids, alkalis and alcohol. For this reason, TPX is used in various applications which require chemical resistance, such as cosmetic container caps and tubes, experimental apparatus and analytical cells.

Applications: Experimental Apparatuses

Gas Permeability

TPX has a characteristic of excellent gas permeability derived from its molecular structure. Hence, TPX is widely used for gas permeative applications such as gas separation membranes.

Applications: Hollow Fiber

Low Dielectric Property

Since TPX has a non-polar structure; its dielectric property is almost same as fluorine polymers. It should be noted that dielectric property of TPX is hardly affected by frequency and TPX can be injection-molded unlike PTFE. TPX shows stable dielectric property in the wide range of frequency.

Low Density

The density of TPX is the lowest (830 kg/m3) among thermoplastic polymers, and its specific volume is larger than that of other transparent polymers. For this reason, it is possible to reduce the weight of injection-molded articles by using TPX or also TPX compounds.

Applications: Food Containers, Animal Cage

Steam Resistance

TPX shows a very low water absorbance and therefore the dimension of a TPX product is hardly affected by water absorbance. Furthermore, since TPX does not hydrolyze in boiling water, it can be used for experimental apparatus and animal cages which require the steam sterilization.

Applications: Hollow Fiber, Experimental Apparatuses, Animal Cage

Food Sanitation

Hygienic approved TPX grades (JPN standards, FDA and EU regulations) are also available. And with its excellent heat resistance property, TPX is often used for food wraps and microwave oven table ware.

Compliance

Low Refractive Index

The refractive index of TPX is 1.463nD20, lower than fluorine polymers.
