TPX™

TPX™ manufactured by Mitsui Chemicals, Inc. and distributed by Mitsui Plastics is a specialty polyolefin resin (Polymethylpentene, PMP) renowned for its unique combination of transparency, chemical & heat resistance, and exceptional releasability.  As the lowest density thermoplastic, TPX™ enables significant weight reduction in finished products, making it ideal for demanding applications across industries.

TPX™ offers glass-like clarity, a high melting point, outstanding chemical and steam resistance. Its surface tension is extremely low, providing superior peeling and release properties.

• Exceptional transparency and clarity – comparable to glass or acrylic​​
• High heat resistance, suitable for steam and autoclave sterilization, microwave applications​​
• Superior releasability and low surface tension for easy peeling and release films​​
• Lightweight – one of the lightest weight thermoplastics for commercial use​​
• Excellent chemical resistance, including strong hydrolysis resistance​​
• Outstanding electrical insulating properties​​
• Minimal water absorption, ensuring dimensional stability​​
• Versatile processing: injection molding, blow molding, extrusion​​
• Certified for food contact in US, EU, China and Japan​​
• Ideal for medical, industrial, and packaging applications​​
• Does not require drying before use
• Non-Stick resulting from Low Surface Tension
