TPX is a crystalline polyolefin made from 4-methylpentene-1, produced by Mitsui Chemicals’ special technology of molecular design and catalyst. TPX DX324 is a high rigidity, transparent polymethylpentene that offers an exceptional combination of properties:

• Excellent transparency – clear and colorless

• High rigidity – rigid and dimensionally stable

• Superior releasability – easy release from molds

• Low density – one of the lightest polymer materials among thermoplastics (0.833 g/cm³)

• Heat resistance – suitable for high-temperature applications

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

TPX DX324 is suitable for injection molding and extrusion processing, with applications ranging from FPC release films to rubber hose mandrels and LED molds. The material is also certified for food contact applications and is halogen-free, making it an environmentally-friendly choice.

Key Features of TPX DX324

• High Rigidity – Rigid material with good dimensional stability; rigidity exceeds polypropylene above 100°C and exceeds PC above 150°C

• Lowest Specific Gravity Among Plastics – Density of only 0.833 g/cm³ – significantly lighter than PC, PMMA, or glass

• Superior Optical Clarity – Clear and colorless transparent appearance; light transmittance does not change with processing conditions or product thickness

• High Heat Resistance – Melting point of 227°C; Vicat softening point of 162°C

• Excellent Release Properties – Superior releasability with low surface tension (24 mN/m); prevents sticking and contamination

• Good Chemical Resistance – Good durability against acids, alkalis, and alcohol

• Excellent Electrical Properties – Low dielectric properties; electrical insulation performance better than polypropylene

• FDA Compliant – Compliant with FDA guidelines

• Halogen-Free – Environmentally-friendly material

• Versatile Processing – Suitable for injection molding and extrusion

Typical Applications for TPX DX324

Material Advantages

TPX DX324 is a high-performance transparent resin that delivers:

• High Rigidity – Rigidity exceeds polypropylene above 100°C and exceeds PC above 150°C, making it suitable for load-bearing applications at elevated temperatures

• Lightest Thermoplastic – With a density of only 0.833 g/cm³, TPX DX324 significantly reduces part weight compared to PC, PMMA, or glass

• Exceptional Clarity – Transparency equivalent to glass and acrylic; light transmittance remains consistent regardless of processing conditions or product thickness

• Superior Releasability – Low surface tension (24 mN/m) simplifies mold release and reduces cleaning downtime

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

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

• Design Flexibility – Can be processed by injection molding and extrusion

• Excellent Electrical Insulation – Electrical insulation performance better than polypropylene

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

Typical Properties

Important Notes on Typical Data:

• Values listed are typical and sourced from Mitsui Chemicals official data sheets and PlaBase database. 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 DX324 is not highly hygroscopic but drying at 65-70°C for 4-6 hours is recommended if moisture is a concern.

• Melt Temperature: Recommended melt temperature range is 230-270°C. Lower processing temperatures and shorter residence times (<5 minutes) provide better physical properties.

• 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. 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.
