Flame Retardants
Flame retardants are an essential component of many of the materials we all use in our daily lives. They inhibit or slow down the spread of a fire and their presence could mean the difference between a containable fire and the loss of a home or life. Amspec is proud to play a part in your safety by supplying flame retardant materials appropriate for various industries and applications. Amspec specializes in flame retardants that use chemical reactions in the gas phase to interrupt fires. Brominated compounds undergo thermal degradation in the flame releasing hydrogen bromide which in turn reacts with reactive radicals. The resulting compounds are much less reactive and as a result the fire slows down. Antimony trioxide often works in synergy with halogenated flame retardants. Amspec supplies materials that are used in furniture, mattresses, fabrics, plastics, circuit boards and wiring. If you would like to find out more about the flame retardants we have to offer please reference the list on the left hand side of your screen. Click on any product to see its technical datasheet which includes information on chemical and physical properties as well as appropriate applications.
Antimony Trioxide
Antimony trioxide, also known as antimony oxide or Sb2O3, is the most widely produced compound of elemental antimony. The nations that produce the most antimony trioxide are China, South Africa, Bolivia, Russia, Tajikistan, and Kyrgyzstan. Typical applications for antimony trioxide include flame retardant synergist for use in plastics, rubber, paints, paper, textiles, and electronics; polyethylene terephthalate polymerization catalyst; a clarifying agent for glass; an opacifier for porcelain and enamel; and a white pigment for paint. When used as a flame retardant, antimony trioxide is often used in combination with halogenated compounds. Antimony trioxide is used as a synergist to enhance the activity of the halogenated flame retardant. In the absence of antimony trioxide about twice as much halogenated compound would be needed to reach the same level of flame retardancy. Four grades of antimony trioxide Amspec is proud to offer four grades of antimony trioxide. Amspec KR grade antimony trioxide is suitable for almost all standard flame retardant and additive applications. Amspec LTS grade antimony trioxide is similar in purity to Amspec KR, but is specifically for applications where you need the tinting strength of the antimony trioxide to be minimized. This low tinting strength grade means you can use…

Additives for Explosives
Amspec has been a leader in the production of antimony oxide derivatives for decades. One of the product lines that Amspec has developed is water gel crosslinkers for explosives and energetic slurry systems. A typical water gel explosive consists of a water solution of nitrates blended with guar gum and a crosslinker and then mixed with solid oxidizers and packaged with a fuel source. Potassium Pyroantimonate or SBP-170 is the best choice for the crosslinker of packaged water gel or slurries systems explosives. The crosslinker must delay gelation so that solids can be easily dispersed and the slurry can be packed but then rapidly and completely gel after packing. The crosslinker must also be easily dispersed into the system. The choice of crosslinker can affect many properties of the explosive. Using an antimony based crosslinker has been proven to improve stability and consistency of the explosive slurry, thermo chemical energy efficiency, safety degree in high velocity impact tests, velocity of detonation, and water resistance. For more information about our explosive crosslinkers please click on the links to the left. If you have any additional questions please call (302) 392-1702.

Metal Anodes
Metal anodes are pieces of metals that are used in electrochemical processes like electroplating or corrosion protection. Many different metals are used such as aluminum, zinc, magnesium, titanium, tin, cadmium, lead, copper, or various alloys such as bronze and brass. Different metals are chosen as anodes for various reasons. For example, some metals are more ductile than others are while some have superior strength. There are two types of metal anodes. Sacrificial anodes are used for corrosion protection. These anodes are chosen because the metal of the anode is more easily corroded than what you are trying to protect. Electrons that are removed from the sacrificial anode are transferred to the protected metal so that it becomes a cathode. The extra electrons allow reduction to occur on the surface of the protected metal rather than corrosion. Plating anodes are used mainly for plating and electroplating applications. Plating is done for several reasons including for aesthetic reasons, for corrosion protection, to harden, to improve paint or coating adhesion, for radiation shielding, or many others. Electroplating is a special process for plating that uses electrical current to facilitate the coating process. Amspec offers various metal anodes in several different shapes and sizes.…
Aluminum Anodes
Aluminum is a lightweight metal with good strength, ductility, and corrosion resistance. Aluminum anodes are often used as sacrificial anodes for many marine applications. The reasoning behind this is that aluminum is reactive enough to act as the sacrificial anode, but not as reactive as other metals like magnesium that can corrode so fast that there can be dangerous consequences to the hull of the boat. In addition, aluminum alloys are environmentally friendly, unlike zinc, which is considered a pollutant. Aluminum anodes can also be used in water heaters. We have aluminum anodes available in almost any shape or size. Please inquire about your specific requirements.
Magnesium Anodes
Magnesium anodes have good corrosion resistance, moderate strength, low density, and good ductility. They are often used as sacrificial anodes in home water heaters. One magnesium anode should last around six years, which is why most water heaters have a six year warranty. The anode is there to protect the small amount of exposed steel in the water tank and prevent leaks. Magnesium sacrificial anodes are also used in marine applications. Magnesium anodes are available upon request. Please contact use with your size and shape requirements.
Tin Anodes
Tin anodes are used most often in plating and electroplating situations. You can use tin anodes to plate both ferrous and non-ferrous surfaces. The food processing industry uses many pieces of equipment plated with tin because it is non-toxic and corrosion resistant. Tin is an extremely ductile metal so it is can be formed easily into a variety of shapes once it coats the surface of another material. Tin can be used as a sacrificial anode, but not for steel. It is only appropriate to protect copper, nickel or other non-ferrous metals. It is used most widely as a sacrificial anode in the electronics industry. Amspec has both hanging and basket tin anodes available in a variety of shapes and sizes. Please inquire about your specific requirements.
Zinc Anodes
Zinc anodes are commonly used as sacrificial anodes to prevent the corrosion of iron surfaces. You will find zinc sacrificial anodes used in marine and naval applications and well as for pipelines. Zinc anodes are also used to prevent the corrosion of canals in major waterways. Zinc anodes can also be used for plating applications. We can supply zinc anodes in almost any shape or size. Please inquire about your specific requirements.
