PDF-Granulate for injection moulding and extrusion

Mouldable like plastic Robust like wood Consistently homogenised Complies with the German standards for toys and food products Contains no formaldehyde chlorine or phenol odourless RecyclableNatural. Its low density high transparency and high gloss sidewall strength at high temperature and greater freedom from environmental stress cracking make polypropylene the material of choice for hollow packaging Polypropylene is mainly used in cosmetics de Polymer Processing. Plastic Products. Plastics can be shaped into a wide variety of products: . Molded parts. Extruded sections. Films. Sheets. Insulation coatings on electrical wires. Fibers for textiles .
