Flame Retardant Grade – F – Building Material Thermal Insulation

F-flame retardant grade has passed the United States Safety Testing Laboratory (UL) certification, document certification number E360952. F-flame retardant grade in the processing process to avoid mixing non-flame retardant substances, especially pay attention to must not be mixed with ordinary EPS, these improper processing methods will reduce the flame retardant performance.

Product introduction
F-flame retardant grade has passed the United States Safety Testing Laboratory (UL) certification, document certification number E360952. F-flame retardant grade in the processing process to avoid mixing non-flame retardant substances, especially pay attention to must not be mixed with ordinary EPS, these improper processing methods will reduce the flame retardant performance. The national standards for F-flame retardant grade are: adiabatic molded polystyrene foam (GB/T10801.1-2002); Classification of combustion performance of building Materials and products (GB8624-2012). In order to obtain B2 flame retardant performance, give the formed product a certain aging time to let the residual blowing agent escape from the foam plastic body, the aging period is mainly based on the foaming agent content, apparent density, product size and other conditions, in the state of good ventilation, on the board products, recommend the following empirical data:

15KG/M³  : 20mm thick, at least one week aging period 20mm thick, at least two weeks aging period
30 KG/M³ : 50mm thick, at least two weeks of aging 50mm thick, at least three weeks of aging

Product characteristics
1, good flame retardant performance;
2. Fast pre-delivery speed;
3. Uniform particle size of raw materials, good fluidity of foamed beads;
4, wide operating range, suitable for all kinds of automatic and manual plate making machines;
5, foam bead cell fine and uniform, product appearance smooth and smooth;
6, good dimensional stability, good adhesion, good toughness, high strength;
7, recommend a foaming rate of 35-75 times;
8, suitable for B2 standard building materials.
