Typical Applications for TPX MX002

Material Advantages

TPX MX002 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 and gas separation applications

• Lightest Thermoplastic – With a density of only 0.833 g/cm³, TPX MX002 significantly reduces part weight compared to PC, PMMA, or glass

• Exceptional Clarity – 93% 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 film extrusion, extrusion coating, blow molding, fiber extrusion, and injection molding

• Excellent Electrical Insulation – High volume resistivity (>10¹⁶ Ω·cm) and dielectric strength (65 kV/mm)

• 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

Typical Properties

Important Notes on Typical Data:

• Values listed are typical and sourced from Mitsui Chemicals official data sheets. They do not constitute binding product specification.

• Batch-to-batch deviations may exist. For critical applications, validate performance with batch-specific COA certificate.

• Final performance depends on processing conditions, mold design, and part geometry.

• Mitsui Chemicals official TDS shall serve as definitive technical reference. Request the latest official TDS from our sales team.

Processing Guidelines

Critical Processing Warnings:

• Drying: TPX MX002 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 film extrusion, extrusion coating, blow molding, fiber extrusion, and injection molding.

• 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: 1.5%, TD: 1.1%). 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.
