Plastic raw materials for Modified Plastic
-
The mechanical properties of plastic products, including rigidity, flame resistance, impact strength, and toughness, can be considerably improved by the addition of a variety of reinforcing additives, including talc powder, flame retardants, and functional masterbatches, during product production. Modified plastic components can even achieve the same strength levels as steel, while still maintaining their advantages of being lightweight, colorful, and simple to mold. This makes them ideal for large-scale applications in industries like automotive parts and home appliance manufacturing.
When compared to unfilled polymers, the creep resistance of polymers that include talc powder is substantially higher. Polymers filled with talc, especially those containing high aspect ratio talc, have been shown to exhibit superior mechanical performance, according to extensive research. The performance hierarchy follows this order: high aspect ratio talc powder ＞ medium aspect ratio talc powder ＞ talc and calcium carbonate blend ＞ calcium carbonate ＞ unfilled polypropylene. These materials are significantly stronger and more stable compared to unfilled and calcium carbonate-filled polypropylene.
Our industrial-grade talcum powder is a filler powder commonly used in plastics, resins, paints, and ceramics. Featuring a whiteness range of 70-100% and particle sizes between 2.5μm and 15μm, this talc stands out for its excellent dispersibility. It’s widely applied in various industries such as rubber, composite materials, household appliances, automotive parts, and even honeycomb ceramics.
Many polymers can be improved in terms of flame resistance and smoke suppression by adding halogen-free flame retardants during the modification process. The processing temperature is more important for their thermal stability than for halogenated flame retardants. When the temperature is too high, the flame retardant may degrade, and when it's too low, the plasticization won't be enough, which might compromise the product's functionality.
Magnesium hydroxide, also known as brucite (Mg(OH)₂), is a non-halogen flame retardant and smoke suppressant used in industries such as plastics, rubber, polyurethane (PU), fibers, and coatings. Derived from minerals like magnesite and dolomite, our magnesium hydroxide undergoes an advanced process of purification, fine grinding, and surface treatment to ensure high whiteness, fine particle size, and efficient flame retardancy.
By incorporating functional masterbatches into the production process, manufacturers can effectively improve the surface rigidity of plastics, significantly enhance the heat resistance of PP products, and improve surface gloss, acid, alkali, and heat resistance. These masterbatches are essential raw materials for engineering plastics, sheets, pallets, high-grade automotive parts, bumpers, heat-resistant appliance casings, and sanitary ware.
PP filler masterbatch is produced using PP as the carrier resin, combined with dispersing agents and special additives, followed by surface activation and extrusion. This masterbatch enhances the rigidity and heat resistance of PP products, improving surface smoothness and gloss.
