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 Proceeeing Condition

●Material Selection

Select proper bead diamaters according to the required shape and density of the final product. Large articles in medium and low density (less than 16g/I) require 302XS or 301XS. Continuous pre-expanders require 302XS or 303XS while batch pre-expanders require 303XS/ 401XS / 501XS.

●Pre-expansion

Steam Pressure: 0.15MPa-0.30MPa

Pre-expansion Temperuture: 96-108℃

Condition Time: 4-24 Hours

●Moulding

Steam Pressure of Stationary Mould: 0.7-1.2kgf/cm2

Steam Pressure of Moving Mould: 0.75-1.2kgf/cm2

Health and Safety

●Fast cycling grade totally meets food cintact safe requirements as is less than 0.2% wt/wt. The total comtent of aromatic hydrocorbon impurities are far lower than the one in similar competitive products.

●During storage, transportion and processing, low levels of pentance blowing agent will be present, which will have an explosive range in air between 1.1-6.0%. The raw material and products must therefor be well ventilated and kept far away from sourse of ignition including static electricity.
