Polyester Blasting Media

Introduction of Polyester Blasting Media

Polyester blasting media is a soft abrasive that may be employed to deflash electrical components without causing deterioration to light parts & blast composites, plastics, & fiberglass. Plastic blast media is unrestricted from Shot Blaster in a multitude of assortments & hardness levels, such as Acrylic, Melamine, Clear-Cut, & Urea. For paint stripping & blasting composites, plastics, & fiberglass, utilize polyester blasting media & plastic blasting media, which are soft abrasive grits. To deflash electrical elements without causing impairment to delicate parts, polyester blasting is also employed. Plastic media certainly the softest is polyester. The United States Army, Navy, & Air Force have approved the usage of polyester blasting media, which satisfies Mil-Spec MIL-P-85891A standards. Electronics & paint or coatings are two industries. We are one of the best polyester blasting media Manufacturer in India.

Types of Polyester Blasting Media

Media types for plastic media blasting. The plastic media industry has transformed tremendously in recent years. When the US military began operating plastic media blasting, it authorized simply three types of plastic media, all thermosets: Polyester Type I, Type II, Urea formaldehyde; & Type III, Melamine formaldehyde.

Type I Polyester Blasting Media

Type I, Polyester is the softest plastic media type & is employed only of the most delicate substrates. The first plastic abrasive developed was unfilled polyester. plastic abrasives utilized in abrasive blasting machine operation were still identified & utilized accepting their existing physical characteristics and properties. In order to acclimate these abrasives to separate applications, particle size & additional process parameters were adjusted. Polyester living fairly feeble was considered a very delicate abrasive & was widely utilized in electronics for cleaning printed circuit boards, & in some aerospace applications for thermal spray coatings removal from composites & thin-skinned materials. However, on modern coatings, polyester was not considered to be fast enough for large production depaint operations, which lead to the development of the second material.

Type II Polyester Blasting Media

Polyester blasting abrasive media Type II, which is urea formaldehyde. While polyester raw material had come from the button industry, urea formaldehyde was traditionally employed in the electronics industry for light switches & wall plate covers. These materials fell within the family of thermosets, which are plastics which cannot be reheated & reformed. Type II, urea, became an industry workhorse, being highly productive & durable. It was reinforced with alpha cellulose fiber & could release thermal spray coatings at a heightened rate of speed. Type II was broadly employed on aircraft evolving the media of alternative for depainting the entire fleet of F-4 Phantom fighters & CH-47 Chinook helicopters. During that period of time, Republic Airlines also stripped a number of commercial aircraft before their acquisition by Northwest. During these early days, the processes were very operator sensitive with thin margins of error and required a high degree of control of process parameters.

Today, Type II polyester blasting abrasive media  are primarily used for engine overhaul, component cleaning, landing gear, wheel and brake, AGE equipment and other durable components of the aerospace industry. Outside of aerospace, it is used in manufacturing processes, cleaning castings, molds, sand blasting machine operation, and other hardened aluminum or steel components. In some instances, it is used for profiling softer substrates such as graphite epoxy. The third abrasive media to come along was melamine formaldehyde, which primarily comes from the non-breakable dinnerware industry. 

Type III Polyester Blasting Media

Polyester blasting abrasive media was harder than the Type II & had a hardness of 4.0 on the MOHS scale. This material has principally been utilized for removing tenacious thermal spray powder coatings & cleaning harder coatings or contaminants from durable surfaces. Melamine in fine sizes is also extensively utilized in the integrated circuit industry for deflashing.

Type IV Polyester Blasting Media

Type IV, phenol formaldehyde, did not prove popular with users & the next material developed was a high molecular weight cast acrylic. Type V acrylic had a hardness of 3.0 but had a reduced density of 1.2 combined with durable cutting edges & reusability.

Type V Polyester Blasting Media

Type V. For thin aluminum components, acrylic has been shown to be the most often used plastic abrasive media. Compared to Type II, it is less aggressive and has lower elimination rates. It is quite long-lasting and might be a decent option if you simply want to remove the topcoat, even though it won't remove many primers.

Type VI Polyester Blasting Media

Type VI. While considerably harsher on coatings than Type I, poly all yl glycol carbonate is quite safe on the majority of substrates. Especially when applied to composites, it has good removal rates. A composite product with an unsatisfactory thermal spray wire coating used to be trashed since there was no secure method for removing it. Because it avoids using the costly portion, a removal rate of only 1/2 square foot per minute is deemed cheap. Higher than one square foot removal rates per minute are not out of the ordinary, particularly for coatings thinner than five mils.
