Plastic media is used in tumbling, other finishing, and Sand blasting machine procedures. Plastic blast medium enables for the removal of paints or organic coatings without abrading the underlying metal substrate. Plastic grit is used to clean surfaces, remove powder coatings, and abrade gel coats and printed circuit boards (PCBs). Product specs include material kind, hardness measurement, and mesh type. Plastic media and abrasives may comprise a variety of plastic compounds, but common options include polyester, urea, melamine, and acrylic. Specialized plastic abrasives are also available. Hardness is often tested using the Mohs and/or Barcol scales. There are various common mesh types for each type of plastic abrasive media or abrasive substance.
Plastic media is a type of blasting media that is made of various types of plastic materials, such as acrylic, polyester, urea, and melamine. Plastic media blasting is a popular alternative to traditional sandblasting because it is less abrasive and less likely to damage the surface being cleaned or prepared.
Plastic Blasting Media
Plastic blasting media is a versatile abrasive that can be utilized in a wide range of applications. It is a lightweight, angular-shaped media that is widely used to remove paint or other coatings from sensitive substrates such as aluminum or composites.
Plastic media blasting is a quick, cost-effective, and safe approach to removing coatings from virtually any surface. The technique is theoretically similar to sandblasting. At low blasting pressures of 14-40 psi, however, much softer reusable plastic particles are used instead of hard silica sand. At these pressures, the plastic medium can remove coatings without hurting the underlying substrates, which can be comprised of aluminum, fiberglass, or even plastic.
Composing Materials to meet the needs of diverse automotive finishes and substrates, and we offer a wide choice of plastic abrasive blasting media at affordable prices in India, and also provide glass beads, steel shots, aluminum oxide, garnet sand, quartz sand, silicon carbide, and copper slag. Individual plastic granules are arranged asymmetrically and have sharp, angular edges on their surfaces. During use, an efficient cutting, shearing, and lifting motion occur. Because of the unique physical qualities of plastic media, the build-up is eliminated without etching, marring, warping, or otherwise damaging sensitive surfaces, preserving critical surface integrity.
Plastic Media Features
Here are some common features of plastic media:
- Shape and size: Plastic abrasive blasting media can come in a variety of shapes and sizes, depending on the application. Some common shapes include cylinders, cones, stars, triangles, and pyramids. The size of the media can range from as small as 0.5mm to as large as 20mm, depending on the application.
- Density: Plastic media can be made with different densities, which can affect how aggressively it removes material. Lower-density media is generally more gentle and is used for polishing or deburring delicate parts, while higher-density media is used for more aggressive cleaning and surface preparation.
- Abrasive properties: Some plastic media is abrasive, meaning it can remove material from the surface of the workpiece. Other plastic media in India is non-abrasive and is used for cleaning or polishing without removing material.
- Durability: Plastic media in India can be made with different levels of durability, depending on the application. Some abrasive media is designed to be used only once, while other media can be reused multiple times before it needs to be replaced.
- Chemical resistance: Plastic abrasive blasting media can be made with different chemical properties to make it resistant to various chemicals, such as acids, alkalis, or solvents. This is important for applications where the media will be used in harsh chemical environments.
- Compatibility: Plastic abrasive media should be compatible with the material being processed and the equipment being used. For example, some plastic media can cause damage to softer metals like aluminum, while other media is designed specifically for use with these materials.
