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

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.
