Because the combustion behavior of flame retardant materials in fire is very complex, any single combustion test method cannot fully describe the combustion properties of a flame retardant material. Alfa Chemistry is committed to using a variety of flame retardant testing and analysis methods to help customers meet the challenges of flammability analysis of flame retardant materials.
Here, Alfa Chemistry offers comprehensive and systematic analytical testing methods to choose from. Our analytical capabilities include but are not limited to research on the preparation and properties of flame retardants, flame retardant materials and flame retardant treatment technologies, flame retardant mechanisms and evaluation of flame retardant effects.
Horizontal Burning Test
The horizontal burning method refers to a test method in which one end of a material sample is clamped horizontally, the free end is exposed to the flame of a specified gas, and the linear burning rate is measured to evaluate the combustion performance.
Vertical Burning Test
Vertical burning refers to the test method for measuring the time and burning state of the flame burning and flameless burning of the sample in the way that the sample of the specified size and shape clamped at the upper end is in a vertical position and the free end is exposed to the specified gas flame.
Limiting Oxygen Index Test
The limiting oxygen index test is to measure the minimum oxygen concentration required to just maintain the combustion of the polymer sample after fully mixing oxygen and nitrogen in a certain proportion. The higher the limiting oxygen index (LOI) value, the higher the incombustibility.
Cone Calorimetry Test
With the rapid development of flame retardant science and technology, cone calorimetry test is the most representative new test method. Cone calorimeter is mainly used to study the action mechanism of flame retardants, compare different flame retardant behaviors of materials, evaluate the combustion performance of materials, and conduct fire simulation research.
Smoke Density Test
The material burns in the smoke box to generate smoke, and the solid dust in the smoke reflects the light passing through the smoke box, resulting in the loss of luminous flux. The smoke density is evaluated by measuring the change in luminous flux, thereby determining the degree to which the material may release smoke under the conditions of combustion and decomposition.
Microcalorimeters, also known as pyrolytic combustion flow calorimeters (PCFC), typically determine basic chemical heat values within seconds to predict the fire performance of materials. PCFC test is suitable for studying the mechanism of action of flame retardants, comparing the different flame retardant properties of flame retardants used in materials, and evaluating the combustion performance of materials.
Glow Wire Test
Safety is very important in electrical and electronic equipment. The glow wire test is used to determine the flame retardant properties of electronic products, and its purpose is to test the stability of the material during operation. Alfa Chemistry offers glow wire testing services to help you analyze the flammability of polymeric materials and explore their potential in electronic applications.
