NFD high specific gravity plastics are filled with a certain proportion of heavy mineral fillers or metal powders into thermoplastics. This material still has the plasticity of plastics and some properties can meet the requirements of metals. It has the texture of metals. High specific gravity plastics features: high density, easy processing, metal texture, X-ray shielding, etc, in automotive manufacturing, electronic and electrical fields, the use of high specific gravity plastics instead of lead products can achieve green environmental protection of materials. Low specific gravity plastics mainly achieve the goal of reducing the specific gravity of plastics by adding light fillers. Lightweight fillers include: hollow glass beads, phenolic beads, cork powder and other materials. NFD has successfully developed a number of high and low specific gravity plastics according to customer requirements, with rich development experience.NFD has successfully developed a variety of high and low specific gravity plastics according to customer requirements, and has extensive development experience.

The high specific gravity mixed filler is composed of 40%-96% mineral and metal powder. It still has the ability of plastic processing and moulding. The maximum density of this kind of material can reach 15g/cm3. Lightweight density material use calcium carbonate (2.6g/cm3), barium sulfate (4.5g/cm3), talcum powder (2.6g/cm3) and other minerals to replace fillers such as aluminium and ceramics. Medium and heavy specific gravity materials usually use metal fillers such as steel, aluminium and tungsten, which have thermal conductivity and electromagnetic shielding ability. In order to prepare high specific gravity materials, good fluidity matrix resin is needed. According to the good fluidity of PP, PA, PBT, TPU, SEBS, PPS,etc resins, NFD has developed a variety of high specific gravity materials.

With the increase of fillers in plastics, the mechanical properties of high specific gravity plastics decrease gradually, and the processing fluidity of materials decreases.

Effect of NFD Filler Addition on Mechanical Properties of High Specific Gravity Composites:

Glass bead is a kind of micro glass sphere of inorganic non-metallic material. It has the characteristics of light weight, electrical insulation, thermal stability, sound insulation, high temperature resistance, wear resistance, easy dispersion and low thermal conductivity, etc. Glass beads are light in weight and large in volume. When used as fillers, they can greatly reduce the density of resin materials, reduce costs, have excellent filling performance in material processing, and have stable size and no warping. The products have outstanding sound insulation, heat insulation and thermal insulation properties.

Application characteristics of NFD glass bead filled composites:

1. Low cost.

2. Increase the toughness and strength of plastics while maintaining the rigidity of plastics themselves.

3. Increase the softening temperature and flame retardant effect of micro-card.

4. Good electrical insulation.

5. Increase material processing fluidity.

6. Low shrinkage and good dimensional stability.

7. Excellent corrosion resistance, heat insulation and sound insulation.
