Description
PU 3410
ALCHEMIX PU 3410 is a soft flexible polyurethane system of 40 shore A, it has a low viscosity and is used for mould making or prototype parts requiring highly elastomeric properties.  
PU 342
ALCHEMIX PU342 is a two component soft and flexible polyurethane system for mould making or prototype parts requiring elastomeric properties. Very low viscosity.
PU 3425
ALCHEMIX PU3425 is a hard but flexible PU for moulding parts where semi rigidity is required.
PU 3426
ALCHEMIX PU 3426 is a tough flexible polyurethane system of 57 – 63 Shore A, designed specifically for offshore applications requiring good tensile strength and chemical resistance. The system exhibits a rapid development of properties while retaining a relatively long useable life.
PU 343
ALCHEMIX PU 343 is a semi flexible polyurethane system of 87 – 92 Shore A, used for mould making or prototype parts requiring semi rigidity.
PU 3435
ALCHEMIX PU 3435 is a tough elastomeric polyurethane system designed specifically for offshore uses requiring high tensile strength and chemical resistance. The system exhibits rapid development of properties while retaining a relatively long usable life
PU 3436
ALCHEMIX PU 3436 is a tough, elastomeric polyurethane system specifically formulated for use as a shock absorber in off shore applications. ALCHEMIX PU 3436 is exceptionally hydrophobic and will cure in damp conditions or when completely submerged in water.
PU 3436F
ALCHEMIX PU 3436F is a tough, elastomeric polyurethane system specifically formulated for use as a shock absorber in off shore applications. ALCHEMIX PU 3436F is exceptionally hydrophobic and will cure in damp conditions or when completely submerged in water.
PU 3501
ALCHEMIX PU 3501 is a flexible polyurethane moulding system with excellent tear strength and high elongation. ALCHEMIX PU 3501 is formulated for a broad field of applications where a high degree of flexibility and strength is required.
PU 3523
ALCHEMIX PU 3523 is a tough, durable, polyurethane elastomer of 50 Shore A, used for mould making or prototype parts requiring high tear strength and excellent abrasion resistance.
