Description
PU 342
PU 342 is a flexible polyurethane system of 55-60 shore A, used for mould making or prototype parts requiring semi rigidity.
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 3434F
ALCHEMIX PU 3434F is a tough flexible polyurethane system of 78 – 83 Shore A, designed specifically for offshore applications requiring good tensile strength and chemical resistance. The system has a fast cure and exhibits a rapid development of properties.  
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 3438
ALCHEMIX PU 3438 is a tough, elastomeric polyurethane system specifically formulated for use as a shock absorber in off shore applications. ALCHEMIX PU 3438 is exceptionally hydrophobic and will cure in damp conditions or when completely submerged in water. ALCHEMIX PU 3438 has a renewable raw material content of 47%. The product is available in high visibility orange or unpigmented (ALCHEMIX PU 3438 Natural).
PU 3438F
ALCHEMIX PU 3438F is a tough, elastomeric polyurethane system specifically formulated for use as a shock absorber in off shore applications. ALCHEMIX PU 3438F is exceptionally hydrophobic and will cure in damp conditions or when completely submerged in water. ALCHEMIX PU 3438F has a renewable raw material content of 47%. The product is available in high visibility orange or unpigmented (ALCHEMIX PU 3438F Natural).
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 3543
ALCHEMIX PU 3543 is a tough, durable, polyurethane elastomer of 30 Shore A, used for mould making or prototype parts requiring high tear strength and excellent abrasion resistance.  
PU 3544
ALCHEMIX PU 3544 is a tough, durable, polyurethane elastomer of 40 Shore A, used for mould making or prototype parts requiring high tear strength and excellent abrasion resistance.
