Biodegradable thermoplastic material designed for injection molding applications
* to order biogranucat we invite you to contact us by phone or email 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 200°C. It is advisable to prevent long-term stagnation of the material in the cylinder, otherwise thermal degradation may occur, which will lead to production instability and deterioration of the properties of the products. Character/Color The product is in the form of beige-colored granules. Only carry out staining based on staining concentrates supplied 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 waterlogging. 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
