Product Overview
Description
EPS(Expandable Polystyrene) is a lightweight, rigid, plastic foam insulation material produced from solid particles of polystyrene. Expandsion is achieved by virtue of small amounts of pentane gas dissolved into the polystyrene base material during production.The gas expands under the action of heat, applied as steam, to form perfectly clesed cells of EPS.
How do we classfiy EPS Material?
Regular Grades - High Expansion, Medium Grade, Fast Cycling, Colorful beads
Flame Retardant - High Ratio Flame Retardant, Low Pentane Flame Retardant.
Fast cycling grade EPS confers excellent processing and product properties Consistent raw beads and good fluidity of foamed bead. No harmful odors in pre-expansion and moulding Short maturing time Characteristically rapid cooling in automatic molding machines and better performance with vacuum system Uniform cell size, beautiful and flat surface appearance Good integration inside, high resistance Use in contact with food Recommended 40-60 expansion ratio.
Recommended Processing ConditionMaterial Selection Select proper bead diameters according to the required shape and density of the final product. Large articles in medium and low density (less than 16g/l) require D-104 or D-103. Continuous pre-expanders require D-104 or D-105 while batch pre-expanders require D-105/D-106/D-107. Pre-expansion Steam Pressure: 0.15Mpa-0.30Mpa Pre-expansion Temperature: 96-108℃ Conditioning Time: 4-24 Hours Moulding Steam Pressure of Stationary Mould: 0.7-1.2kgf/cm² Steam Pressure of Moving Mould: 0.7-1.2kgf/cm²
Health and SafetyFast cycling grade totally meets food contact safe requirements as is less than 0.2%wt/wt. The total content of aromatic hydrocarbon impurities are far lower than the one in similar competitive products. During storage, transportation and processing, low levels of pentane blowing agent will be present, which will have an explosive range in air between 1.1-6.0%. The raw material and products must therefore be well ventilated and kept far away from sources of ignition including static electricity. Flame retardant EPS grades confer excellent processing and product properties Consistent raw bead and good fluidity of foamed bead Rapid expansion Relatively low density in second-time expansion. Excellent flame retardation with the US UL Product Security Certification. Wide range of operation and suitable for various block machines, automatic machines and manual presses. Fine cell, beautiful and flat appearance. Low shrinkage rate of block in molding. Recommended 40-70 expansion ratio to increase as per several-time expansion.
