{"id":12,"count":6,"description":"<strong>Polyolefins (polypropylene PP, polyethylene PE)<\/strong> \u2014 the largest class of thermoplastics by volume. Material Wizard supplies virgin and recycled polyolefin compounds for packaging, technical products and series production.\r\n\r\nPP vs PE \u2014 key differences\r\n\r\n<strong>Polypropylene (PP)<\/strong> \u2014 density 0.90-0.91 g\/cm\u00b3, melting temperature 160-170 \u00b0C, stiffer than PE, better flex resistance, suitable for parts with hinges (living hinges). Withstands 100-110 \u00b0C in continuous service.\r\n<strong>Polyethylene (PE)<\/strong> \u2014 density 0.915-0.965 g\/cm\u00b3, melting temperature 110-135 \u00b0C, softer and more impact-resistant. Continuous service up to 60-80 \u00b0C. Better low-temperature resistance.\r\n\r\n\r\nHomopolymer \/ Block copolymer \/ Random\r\n<strong>PP homopolymer<\/strong> \u2014 maximum stiffness and melting temperature. Suitable for rigid housings, thin-walled parts, packaging.\r\n<strong>PP block copolymer<\/strong> \u2014 additionally contains ethylene blocks that improve impact resistance at low temperatures. The standard for industrial containers and automotive parts.\r\n<strong>PP random copolymer<\/strong> \u2014 statistically distributed ethylene units. High transparency, flexibility, better organoleptic properties. The standard for transparent packaging, medical products and food containers.\r\n\r\nPolyethylene density and MI\r\n\r\n<strong>HDPE (High Density)<\/strong> \u2014 0.941-0.965 g\/cm\u00b3. Rigid, chemically resistant; for pipes, canisters, technical products.\r\n<strong>LDPE (Low Density)<\/strong> \u2014 0.915-0.935 g\/cm\u00b3. Soft, flexible; for films, bags, insulation.\r\n<strong>LLDPE (Linear Low Density)<\/strong> \u2014 linear LDPE with better mechanical properties. The standard for stretch film and packaging.\r\n\r\n<strong>Melt Flow Index (MFI)<\/strong> characterizes melt flowability: low MFI (0.5-2) \u2014 for extrusion and blow molding; medium (5-15) \u2014 for injection molding of large parts; high (20-40) \u2014 for molding small parts and for stretch films.\r\n\r\nRecycled PP\/PE \u2014 cost-effective solutions\r\nMaterial Wizard offers <strong>certified recycled polyolefins<\/strong> with controlled particle size distribution, impurity removal and stabilization. This means <strong>a price 30-50 % below virgin material<\/strong> while retaining 80-95 % of the properties, depending on the application.\r\n<strong>Applications of recycled PP\/PE:<\/strong>\r\n\r\nTechnical products where food-contact certification is not required \u2014 canisters, crates, pallets.\r\nConstruction materials \u2014 pipes (non-potable water), roofing elements, sewerage.\r\nAgricultural packaging, storage containers.\r\nGeomembranes, drainage systems.\r\nFurniture fittings, technical components.\r\n\r\n\r\nComposite solutions for PP\/PE\r\n\r\n<strong>PP GF30<\/strong> \u2014 polypropylene with 30 % glass fiber. Flexural modulus 5-7 GPa, HDT 140-150 \u00b0C. An alternative to PA GF30 in relatively dry applications.\r\n<strong>PP-T (talc)<\/strong> \u2014 mineral-filled PP for stiffness and dimensional stability.\r\n<strong>PE-X (cross-linked)<\/strong> \u2014 for hot-water supply lines and heating systems.\r\n\r\n\r\nCompatibilizers for PP\/PE blends\r\nWhen PP and PE or their recyclates are blended, mechanical compatibility decreases. <strong>Compatibilizers<\/strong> based on MAH-functionalized PP\/PE restore adhesion between the phases and bring properties back to 80-95 % of the virgin-material level.\r\n\r\nHow to choose a polyolefin for your product\r\nMaterial Wizard will help you select the optimal PP\/PE compound: copolymer type, MFI, filler content, additions of UV stabilizers, antistatic agents and flame retardants.
