ALPHA-PLAST PUR foam. the consistent further development of the earlier ones Degaplast PUR rigid foams. ALPHA-PLAST has fine pores. with delayed reaction and therefore with a longer processing time. ALPHA PLAST Workpieces are characterized by the lowest shrinkage and a high heat resistance. ALPHA-PLAST 700 is a high-strength rigid foam with a density of 700 kg/ m³ and a foaming factor of 1.6. Ideal for orthopedic shoe lasts. ALPHA-PLAST 300 is a light rigid foam with a density of 300 kg/m³ and a foaming factor of 3.7. ALPHA-PLAST 200 is the lightest hard foam from the ALPHA-PLAST line. He has a density of approx. 200 kg/m³ and a packing factor of 5.5. He suits also suitable for embedding butt sleeves. The ALPHA-PLAST - A components are pink. the workpieces from it also become rosé. ALPHA-PLAST-B. is used as the B-component for all ALPHA-PLAST settings used.
