Research & Development
Polimarky’s success was made possible by the resilience and curiosity of highly skilled, creative people. We currently hold four patented solutions for processes in recycling, thermoplastic polymer compounding, and materials themselves, ensuring the safety, quality, and purposefulness of our products.
Our products apply widely in many different industries
We design the products consciously, thinking about their lifecycle long after we deliver them to the customers. Our team’s top priority is to ensure the longevity and quality of our products, as they benefit the end-users and our planet. We track our feedstock origins and supplier’s practices.
Testing services
Our state-of-the-art, well-equipped laboratories can help you in many ways. We do not only use them to test our products, but also provide testing services. Click below to see our capabilities.
We offer comprehensive technological support at every stage of the product life cycle – from raw material verification, through the design of proprietary formulations, to comprehensive testing of finished products. Our laboratory conducts tests based on internationally standardized testing methods.
1. Mechanical and Strength Properties
- Tensile test: stretching a plastic specimen at a constant speed until it breaks in order to measure its resistance and behavior under applied force ISO 527-1, 2
- Flexural test: ISO 178
- Impact strength:
- Charpy method – ISO 179
- Izod method – ISO 180
- Hardness of plastics: measurement on the Shore scale (types A and D) – PN-EN ISO 868
2. Rheology and Polymer Processing
- Flow properties of plastics: melt mass-flow rate (MFR) and melt volume-flow rate (MVR) – ISO 1133
- Moisture content: moisture content in granules (moisture analyzer method)
3. Thermal and Physicochemical Properties
