Gypsum Plaster Icosahedron

Process:
Molded using 2 pieces of foam milled into the icosahedron split in half. Each half milled into one of the foam pieces, then the 2 halves are faced and clamped together (milled part to the inside) then slow drying plaster is poured into a hole that has been carved vertically in the middle of the mold. left to dry for an hour.

POLYSTYRENE CRYSTAL

FORMULA/ CHEMICAL COMPOSITION

MATERIAL DESCRIPTION

All polystyrenes have excellent process ability and a low heat capacity value leading to process energy reduction. With its high stiffness and low density, all articles made from polystyrene have excellent strength-to-weight ratio offering many environmental benefits, such a reduction of weight, nonrenewable resource savings, transportation costs and carbon footprint.

EXTRACTION PROCESS

Methanol extraction out of polystyrene at 100 ‘C and requires 6 hours

BASIC PROPERTIES

COMPRESSIVE STRENGTH (N/M2) 10-60 PSI 69.000- 413.000

TENSILE STRENGTH (N/M2) 46 x10^6 – 60×10^6

STIFFNESS (N/M2) 3000 x10^6 – 3600 x10^6

DENSITY (KG/M3) 16 – 640

CARBON FOOTPRINT (AVERAGE, KGCO2E/KG) 1.87

RECYCLABLE YES
