Product Description: Thermoplastic material of 100% biological origin, produced from annually renewable plant resources, GMO-free. Designed for injection molding applications. Under natural conditions, it is fully biodegradable and compostable. Processing conditions: The material is designed for injection molding. The product has hygroscopic properties, so it is supplied in airtight packaging that should be unsealed immediately before use. It is not required to dry the product before processing. However, it is advisable to protect the granules from moisture at any stage of processing, as well as during storage in unsealed packages. Processing parameters: Feed zone temperature below 30°C Plasticizing zone temperature in the range of 160-200°C Mold temperature below 30°C The material is not compatible with plastics, so cleaning of the injection system is required to avoid microplastic contamination. Do not overheat the material above 200o C. It is advisable to prevent prolonged stagnation of the material in the cylinder, otherwise thermal degradation may occur, which will lead to production instability and deterioration of product properties. Character/Color: The product is in the form of beige-colored granules. Only carry out staining based on the staining concentrates provided by the manufacturer. Storage: Store granules in airtight containers in a dry and cool place away from direct sunlight and any external heat sources. The package must be tightly closed until the material is used and resealed after use to avoid water contamination. If the granules are soggy, it is recommended to dry them before use for at least 3 h, at 60°C. Packaging: Barrier: 25 kg bag, 1000 kg big-bag, 1000 kg octobin Typical properties Unit Nominal value* Test method Physical Density g/cm3 1.30 PN-EN ISO 1183-1 MFR (190°C, 2.16 kg) g/10 min 32 PN-EN ISO 1133 MVR (190°C, 2.16 kg) cm3 /10 min 27 Mechanical Tensile strength MPa 41 PN-EN ISO 527 Elongation at break % 2 Modulus of elasticity at tension GPa 1,8 Bending strength MPa 50 PN-EN ISO 178 Modulus of elasticity at bending GPa 2,6 Charpy notched impact strength kJ/m2 9 PN-EN ISO 179-1 Izod notched impact strength kJ/m2 9 PN-EN ISO 180 Thermal : Softening temperature according to Vicat, method A/10 N °C 65 PN-EN ISO 306 HDT – deflection temperature under load, method B (0.45 MPa) °C 55 PN-EN ISO 75-2 * Typical nominal values are given for information only and should not be considered as specifications.
