Product Benefits

What makes TPX Polymethylpentene a truly stand-out material has to be its long list of outstanding properties which make it ideal across a range of applications including:

High Melting PointHigh Melting Point

High Melting Point

With a melting point ranging from 220 to 240°C, TPX boasts excellent thermal stability. This characteristic makes it suitable for items that require steam sterilization, as it retains its structural integrity even under extreme heat conditions.  

Low Surface Tension and Excellent Peeling CharacteristicsLow Surface Tension and Excellent Peeling Characteristics

Low Surface Tension and Excellent Peeling Characteristics

TPX possesses a low surface tension of just 24mN/m, which contributes to its unique peeling characteristics. These properties make it particularly well-suited for release materials in various applications, such as labels, tapes and protective films.  

High Gas PermeabilityHigh Gas Permeability

High Gas Permeability

Its high gas permeability makes TPX ideal for applications that require efficient gas exchange with its permeability ensures optimal performance in these applications.

Low Water Absorption RateLow Water Absorption Rate

Low Water Absorption Rate 

With a low water absorption rate, TPX maintains its stability and performance even in the presence of moisture. This quality is especially important in applications where resistance to water or humidity is required.

Good Chemical Resistance Good Chemical Resistance

Good Chemical Resistance

It demonstrates remarkable resistance to acids, alkalis and alcohol. This quality makes it highly suitable for manufacturing a range of container types, experimental apparatus and analytical cells that may come into contact with different substances. 

Lowest Density Among Thermoplastic PolymersLowest Density Among Thermoplastic Polymers

Lowest Density Among Thermoplastic Polymers

TPX stands out as one of the lightest thermoplastic polymers available, with a density of only 0.83 g/cm3. This lightweight characteristic not only contributes to ease of handling but also makes TPX an environmentally friendly choice. 

High Transparency and Low Refractive IndexHigh Transparency and Low Refractive Index

High Transparency and Low Refractive Index

Thanks to its high transparency and a haze level of less than 5%, TPX offers exceptional optical properties. Its low refractive index puts it on par with traditional materials like glass or acrylic, making it an excellent alternative in applications where transparency is essential.
