Silicon Nitride Ceramics:
Whether you use PVC, PE, PS or other foam materials, our Silicon Nitride Ceramic Disc are engineered to optimize the foaming process, resulting in high-quality foam with superior structural integrity. From Black Silicon Nitride Ceramic Disc that provide enhanced heat resistance to ceramic structural discs that ensure uniform foaming, our diverse products meet the needs of a variety of foaming applications.
The process of adding appropriate foaming agents to foaming materials (PVC, PE, PS, etc.) to produce microporous structure in plastics. Almost all thermosetting and thermoplastic plastics can be made into foam. According to the cell structure, it is divided into open-cell foam (most of the pores are connected to each other) and closed-cell foam (most of the pores are separated from each other). This is mainly due to the manufacturing method (divided into chemical foaming, physical foaming) And mechanical foaming). The development of plastics technology is changing with each passing day. The development of new materials for new applications, the improvement of performance for existing material markets, and the improvement of performance for special applications can be described as several important directions for new material development and application innovation. NEC has newly developed a plant-based bioplastic whose thermal conductivity is comparable to stainless steel. The company mixes carbon fibers with a length of several millimeters and a diameter of 0.01 mm and special binders into polylactic acid resin made from corn to produce a new type of bioplastic with high thermal conductivity. If 10% carbon fiber is mixed, the thermal conductivity of bioplastics is comparable to stainless steel; when 30% carbon fiber is added, the thermal conductivity of bioplastics is twice that of stainless steel, and the density is only 1/5 of stainless steel. In addition to good thermal conductivity, this kind of bioplastic has the advantages of light weight, easy molding, and low environmental pollution. It can be used to produce thin and light computers, mobile phones and other electronic products. The University of Southampton in the UK and the Darmstadt Plastics Research Institute in Germany have jointly developed a color-changing plastic film. This kind of film combines natural optical effects with artificial optical effects, and is actually a new way to accurately change colors of objects. This color-changing plastic film is a plastic opal film, which is composed of plastic pellets stacked in a three-dimensional space. The plastic pellets also contain tiny carbon nanoparticles, so the light is not only between the plastic pellets and the surrounding material. Reflects at the edge area between the plastic balls, and also reflects on the surface of the carbon nano-particles filled between the plastic balls. This greatly deepens the color of the film. As long as the volume of the plastic pellets is controlled, light materials that only scatter certain spectral frequencies can be produced.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
