Core Product Lines
BIOPLAST Starch-Based Compounds
Biotec’s BIOPLAST product line comprises thermoplastic starch (TPS) compounds derived from potato starch and other plant-based sources. These compounds offer:
- Biodegradability: Certified compostable to EN 13432
- Renewable content: High percentage of bio-based carbon
- Versatility: Multiple grades for different processing methods
- Cost-effectiveness: Competitive pricing compared to other bioplastics
BIOPLAST compounds are used in applications such as bags, films, packaging, and disposable tableware.
PLA Compounds
Biotec develops customized PLA (polylactic acid) compounds with enhanced properties for specific applications. The company’s PLA compounds feature:
- Improved impact resistance: Modified PLA for applications requiring higher toughness
- Enhanced heat stability: Heat-resistant PLA compounds for hot-fill applications
- Optimized processing: Formulations tailored for injection molding, extrusion, and thermoforming
- Blends: PLA blended with other biopolyesters for improved performance
Bio-Based Polyester Compounds
Biotec produces compounds based on various bio-based polyesters, including PBAT, PBS, and bio-based polyamides. These materials offer a range of properties from flexible films to rigid engineering applications.
Technology and Manufacturing
Compounding Expertise
Biotec’s core competency is the compounding of bioplastics — the process of blending base polymers with additives, fillers, and reinforcements to achieve desired properties. The company’s compounding capabilities include:
- Twin-screw extrusion: High-quality compounding with precise temperature and shear control
- Multi-component blending: Combining multiple polymers and additives in a single process
- Reactive extrusion: Chemical modification during compounding to enhance compatibility
- Quality control: Comprehensive testing of mechanical, thermal, and rheological properties
Custom Formulation Development
Biotec works as a development partner for customers seeking customized bioplastic compounds. The company’s R&D team develops formulations based on specific requirements for:
- Mechanical properties (strength, flexibility, impact resistance)
- Processing parameters (melt flow, processing temperature, cycle time)
- End-of-life options (compostability, biodegradability, recyclability)
- Regulatory compliance (food contact, medical, pharmaceutical)
