Q&A of EPS

The Introduction of Fire Retardant EPS FSA

Correct definition retardant grade EPS is actually a self-extinguishing material, ie the material in case of fire when burning will be thawed quickly, but left the fire source that is self-extinguish.
A Flame Retardant Grade EPS applications involving a few concepts:
1.Concepts oxygen index LOI means limiting oxygen index, the maximum oxygen concentration is obtained under test conditions, usually means that the higher the oxygen index retardant material good. Flame Retardant EPS limiting oxygen index test mode to do in GB / T10801.1-2002 in the states: the sample size 150mm × 12.5mm × 12.5mm, the sample aged 28 days, the oxygen index of not less than 30% (oxygen in the air content of 21%), so the oxygen index concept must GB / T2406-93 (analysis) and GB / T10801.1-2002 (determined by) associated with two national standards.
2. Burning grading concept originated GB8624-1997 (flammability of building materials classification methods), is divided into two categories: non-flammable type material (A grade) and combustible materials (Class B). Also according to the degree of Class B flammable subdivided into B1 / B2 / B3. B1 level judged to meet the three indicators: the oxygen index ≥32 (GB / T2406); the average burn time ≤30S, average burning highly ≤250MM (GB / T8333); smoke density rating (SDR) ≤75 (GB / T8627 ). B2 level judged to meet the two indicators: the oxygen index ≥26 (GB / T2406); the average burn time ≤90S, average burning range ≤50mm (GB / T8332).
The application of Expanded Polystyrene Foam:
1.EPS electronic packaging products: Expanded Polystyrene Foam packaging products is currently the lightest packaging material, a lightweight, shock absorption, low slip, cost, easy packaging and other features, is the quality of protective packaging materials. Widely used in home appliances, electronics, machinery, handicrafts, pharmaceuticals and other products packaging industry.
2.EPS tank foam insulation products: EPS foam insulation box products have fresh, insulation resistance, storage and other features. Widely used in aquatic products, fruits, vegetables and packaging, storage and transportation equipment industry.
3.EPS foam insulation board products: Expanded Polystyrene Foam insulation board is a new low thermal conductivity, thermal insulation material, low cost, thermal insulation, sound insulation, moisture, light, energy, construction and convenient, widely used in construction, decoration, warm, greenhouse, cold storage, stage sets and other projects.
