A semi-crystalline polyester that provides a unique set of properties that bridge the gap between consumer packaging and heavy-duty industrial components.
While the world recognizes PET as the standard for beverage packaging, we specialize in its application as a high-performance engineering thermoplastic. When your project demands a material with exceptional dimensional stability, superior chemical resistance, and a high strength-to-weight ratio, PET is the definitive solution.
- Exceptional Barrier Properties: PET offers one of the best barriers against oxygen, water, and carbon dioxide, making it indispensable for applications requiring high purity or long-term chemical containment.
- High Rigidity and Strength: In its engineering (crystalline) form, PET exhibits remarkable stiffness and tensile strength, rivaling more expensive resins in load-bearing applications.
- Low Moisture Absorption: Unlike Nylon, PET’s mechanical properties remain stable in humid environments. This ensures that your parts maintain their "out-of-the-mold" tolerances regardless of atmospheric conditions.
- Sustainability Leadership: PET is the most recycled plastic globally. For clients looking to meet ESG (Environmental, Social, and Governance) goals, Manterra can help integrate high-quality recycled PET (rPET) or bio-based PET into your production cycle without compromising part integrity.
Mastering PET in an injection molding environment requires a sophisticated understanding of polymer morphology. Whether you require an amorphous part for optical clarity or a crystalline part for structural rigidity, Manterra provides the technical oversight to ensure the material performs to its theoretical limits.
- Automotive: Structural components, wiper arm housings, headlamp reflectors, and sensors that must withstand exposure to fuels and road salts.
- Electrical & Electronics: High-voltage connectors, bobbins, smart meter housings, and solenoid components requiring excellent dielectric strength.
- Industrial & Fluid Handling: Chemically resistant pump housings, valve components, and liquid-tight enclosures for harsh industrial chemicals.
- Consumer Goods: High-durability food storage systems, cosmetic packaging, and structural frames for appliances that require a high-gloss, scratch-resistant finish.
