ALCHEMIX PU 3587 is a two component polyurethane foam system, that when mixed gives a medium density soft, elastomeric foam. The foam is self skinning, durable and has excellent physical properties. Typical free rise density is between 140 - 180 kgm, however the foam can be over packed in the mould to give higher densities of up to 500 kgm. The final hardness of the foam can be adjusted by small adjustments to the mixing ratio. The product is ideal for applications requiring a tough, durable foam, such as the manufacture of archery targets.
