TPX is a crystalline polyolefin made from 4-methylpentene-1, produced by Mitsui Chemicals’ special technology of molecular design and catalyst. TPX MX002O is a low modulus, low density, heat resistant polymethylpentene that offers an exceptional combination of properties:

• Excellent transparency equivalent to glass and acrylic (94% light transmittance)

• Lowest density among thermoplastic polymers – only 0.834 g/cm³

• Superior releasability – easy release from molds

• High gas permeability – suitable for gas separation and breathable applications

• Good chemical resistance – durable against acids, alkalis, and alcohol

TPX MX002O is certified for food packaging materials by United States Code of Federal Regulations Title 21 (FDA) and Japan Hygienic Olefin and Styrene Plastics Association (JHOSPA).

Recommended for injection molding, T-Die casting extrusion, direct blow molding, and extrusion by profile, mandrel, pipe and fiber spinning.

Key Features of TPX MX002O

Typical Applications for TPX MX002O

Material Advantages

TPX MX002O is a high-performance transparent resin that delivers:

• High Gas Permeability – Exhibits high gas permeability, making it suitable for applications requiring breathability or gas exchange, such as hollow fiber membranes

• Lightest Thermoplastic – With a density of only 0.834 g/cm³, TPX MX002O significantly reduces part weight compared to PC, PMMA, or glass

• Exceptional Clarity – 94% light transmittance rivals PMMA while offering superior heat resistance and chemical resistance

• Superior Releasability – Low surface tension simplifies mold release and reduces cleaning downtime

• Excellent Chemical Resistance – Strong against acids, alkalis, and alcohol; low water absorption (<0.01%) ensures dimensional stability

• FDA Compliance – Approved for food contact, enabling use in food packaging and food processing applications

• Design Flexibility – Can be processed by injection molding, T-Die casting extrusion, blow molding, and fiber spinning

• Excellent Electrical Insulation – High volume resistivity (>10¹⁶ Ω·cm) and low dielectric constant (2.12-2.15)

• Proven Reliability – Manufactured by Mitsui Chemicals, the world’s sole producer of TPX resins

• Environmental Friendliness – Halogen-free polymer with low density that reduces transportation environmental load

Processing Guidelines

Critical Processing Warnings:

• Drying: TPX MX002O is not hygroscopic and typically does not require drying. If moisture is a concern, dry at 80-100°C for 2-3 hours.

• Recommended Processing: Suitable for injection molding, T-Die casting extrusion, direct blow molding, and extrusion by profile, mandrel, pipe and fiber spinning.

• Gate Design: Pin gate is the most suitable for TPX molds due to excellent flowability. Avoid large gates that can cause residual stress and gate cracks.

• Cooling: Sufficient and well-balanced cooling channels are essential due to TPX’s crystalline nature and larger shrinkage compared to amorphous polymers.

• Surface Finish: Highly polished mold surface is recommended for excellent transparency.

• Shrinkage: Mold design should account for higher shrinkage (MD: 1.6%, TD: 1.3%). Off-center gates are recommended to prevent warpage.

• Regrind: Regrind can be used up to 20-30% with virgin material, provided it is clean and properly dried.
